Audio is not working for me. Anyone else?

DROID RAZR MAXX CM 11 JBX KERNEL

#My personal review:

  • Had to reflash rom for prevent issues
  • Audio working fine
  • Cam working fine
  • Battery Life seems good (cannot say yet, but looks good)
If you face any weird issues (like non working audio), try reflashing your rom (dirty flash rom+ gapps + kernel + whatever you use).
In case this doesn't work, try a full wipe (backup apps + data, callslist, sms/mms, wifi networks and bookmarks before with TiBu) or you should consider using another rom.

Haven't much time to play around with JBX but I flashed it on top of SlimKat 3.2 and Liquid Smooth v3.0 and didn't face any issues whatsoever. With JBX OC 400/1300 I got 11978 comparing to 9156 on 300/1200 with stock kernel.
But, I haven't noticed any difference running JBX on 300/1000 and 400/1300 in real usage, everything is fast and snappy on both frequencies (same goes for stock 300/1200).
Looks like if the rom is good, you don't need any performance tweaks at all, except maybe finding the perfect setting for a good battery life.

hi,

i've been lurking around this forum for a long time and and i wanna say thanks to dtail! I'm still using the latest kernel build for 4.2, and I don't wanna move to Slimkat because, in my experience, Antutu scored much lower, the experience was twitchy and battery drained easily in one day with seldom any use.

@dtail1, i know youve been busy and i fully appreciate your hard work, but you've mentioned before that you'll update the other android versions (no lower than 4.2) with the latest builds of JBX, is that still probably gonna happen or is it out of sight now? Else I'll have to go back to Slimkat and hope the kinks i had before will not be there now :)

At least once a day I get the dead screen, only hardware button backlights turn on issue. I have to reboot and wipe cache and dalvik each time it happens. Any suggestions on how to fix this it happens on every ROM I use. Running 2-22 build with SlimKat 3.6 on a xt912. Thanks a lot!

    2. Issues

    1.1 How can I change the smartreflex minimum/maximum voltage

    What is Smartreflex?
    SR is compareable with an CPU governor but not for scaling frequencies but for voltages. That means SR has a fixed range of voltage (min/max) and calculates the optimal voltage for each CPU frequency. In example on light use of the CPU it scales down to lower voltage - on heavy use it can sclae to higher voltage. This is an efficient system to save power! Compared to EMIF which uses the hardcoded voltages it saves more power because it's variable. EMIF cannot vary between the values.

    This interface has a hardcoded range of 830mV min to 1450mV max. Usually there is no need to adjust these values but irt can be usefull in example when using high overclocked frequencies above 1,5ghz! Usually SR cannot handle frequencies above 1,5ghz and I have hardcoded the maximum range of 1,45mV which should allow SR to handle it. In prior times the users had to turn off SR when OCing above 1,5ghz which causes the CPU to eat more power. But you can try around and report your results.

    CAUTION: Don't raise the maximum SR voltage too high! It can burn your board = no phone anymore! I recommend to not use higher values than 1490mV! As already mentioned: THe default value should be enough!

    ANd also: USUALLY THERE IS NO NEED TO CHANGE ANYTHING ON SR! IF YOU DON'T KNOW WHAT YOU'RE DOING, PLEASE LEAVE IT ALONE!


    Ok, now let's see how to do this:


    Turn ON/OFF SR

    1. Open Trickster Mod
    2. Head to the "Specific section"
    3. Scroll down to "Smartreflex"
    4. You can toggle ON/OFF SR for each component (IVA, CORE, MPU)

    Usually I recommend to keep SR ON because it saves power! But in some cases when overclocking the CPU (MPU) the device could freeze - whether you OCed too much or SR couldn't handle the frequency! In this case you can try to raise the vmax value of SR a little bit (CAREFULLY!) and try again. If it sitll freezes and you're sure that you didn't OC too much, turn SR OFF at least for MPU!



    Maximum Voltage

    Currently there is no app which supports the feature of adjusting the SR vmax value, because I wrote this feature some days ago.

    But in the next Trickster Mod version this option will be supported!


    example:

    # To read the current vmax value. Replace XXX with one of the following:

    sc_core - for core max sr voltage
    sr_iva - for iva max sr voltage
    sr_mpu - for mpu max sr voltage (mpu is most related for CPU scaling)

    cat /sys/kernel/debug/smartreflex/XXX/vmax

    # You will get an output, e.g. for mpu = 1450000 (1450mV)

    # To set a new value, do the following command (replace XXX with a value like above - BE CAREFUL! USUALLY THE DEFAULT VALUE ENOUGH AND YOU CAN LEAVE IT UNTOUCHED!)

    echo XXX > /sys/kernel/debug/smartreflex/XXX/vmax


    Minimum Voltage

    It's easy because Trickster Mod supports it!

    1. Open Trickster Mod
    2. Head to the "Specific section"
    3. Scroll down to "Smartreflex"
    4. Below each SR component (IVA, CORE, MPU) there is displayed a value (usually 830 default) which means this is the lowest scalable voltage for this component. You can try to decrease this value for the case you want to UV a bit more - or raise it a bit for the case you think that the set range is too low and causes freezes on your device.







    1.2 How do I use Live OC (Live OVerclock)?

    This feature allows you to overclock the CPU in realtime. It works with a multiplier value set by the user. The default multplier value is "100", which means: No OC! If you want to raise the OC frerquency, just raise this value step by step.

    FOr my device the maximum working OC value is "111" which means the maximum frequency is running at 1498mhz!

    NOTE: Keep in mind that you tunr Smartreflex OFF for higher freqs than 1500mhz - or raise the maximum SR voltage range for "MPU" a little bit and test if it works.


    Ok, how to use Live oC in action:

    Open Trickster Mod App and swipe to the tab "Specific". There you will find something like this:

    Code:
    MPU OC         [100]

    DON'T TOUCH THE "CORE OC" SECTION, IT WILL CAUSE FREEZES!

    Now slowly increase the value "100" to something higher, e.g. "105". Tap the hook in the right upper corner to confirm. To see your new set of frequencies you can now whether close and restart Trickster Mod or just use any monitoring app like Cool Tool which will show your frequencies in real time. That's it!


    CAUTION: You can damage your phone forever!!!! This feature allows you to set very high frequencies (also up to 2,0ghz...) - That DOESN'T mean that your phone can run these frequencies!


    If your phone freezes or crashes you have probably set too high OC - or your voltage is too low.


    1.3 How do I use Custom Voltage (EMIF)?

    NOTE: This only adjusts the fixed voltage! When you have Smartreflex ON it can still vary! You have to see the bigger picture: This voltage value sets the "middle point" for voltages. Smartreflex is still able to increase or decrease the voltage. When Smartreflex is OFF the CPU will stay on this voltage you set here and probably eats also more power.

    How does EMIF works together with Smartreflex:

    Code:
            -------
            | CPU |
            -------
                |
     ------------------          ------------------
     |Voltage 1015 mV | ---->| SMARTREFLEX ON| = 1015mV +/- "vmax"/"vmin"                                      
     ------------------          -------------------
               |
     --------------------
     |SMARTREFLEX OFF| ----> 1015mV FIXED! No changes!
      -------------------

    Thi smeans if you change the voltage for a scaling step (OPP) while SR is ON, SR will adjust the voltage from this value, means: mV-Value +/- SR vmin/vmax. WHen SR is OFF it will stay on this mV as a fixed value.


    How to adjust the voltage?

    Well, this feature can be used with all generic apps which are supporting voltage settings. But we are prepared well, you can adjust voltages also with the "Trickster Mod App".

    When you open the app, head to the tab "Specific" and below the "Live OC Section" you will find your voltage table, which looks like this:

    Code:
                             <-->
    
    1200                  [1398]
    1000                  [1388]
    900                    [1371]
    ...
    ..
    ..

    Now just tap the arrows in the right upper above the first voltage value and just type or tap (per direction) a value, e.g. "-25". To apply it, confirm by tapping the hook in the right upper corner of your screen. That's it, your new voltage values are now set and applied. And also mind here: If your phone freezes you porbably have set it too low.

    CAUTION: NEVER SET HIGHER VOLTAGE THAN 1490mv here!!!!! Or you might damage your phone FOREVER!
    This voltage is not the same like Smartreflex! But it's still voltage! Just be carefull!!






    1.4 How can I use GPU OC and GPU Governor?


    GPU Overclock doesn't work like Live OC! You cannot really set custom frequencies for the GPU, but you can select and set the maximum frequency from a hardcoded range!

    For the GPU there are the following available frequencies:

    1. 154mhz (FIXED!)
    2. 307mhz
    3. 384mhz
    4. 416mhz

    The minimum frequency of 154 is FIXED! This means you cannot change it because the GPU needs a minimum speed to run with. But the kernel allows you to select the maximum speed. This can be usefull for playing games and also for saving power . In example when not playing games you don't need the GPU to run at 416mhz! Set it to 307mhz in this case and save power.

    When you open Trcikster Mod and head to the "specific section tab", you will find "GPU MAX FREQUENCY" and it's currently set maximum frequency. Tap on it to select your preferred one:

    - 154 Mhz
    - 307 MHz
    - 384 MHz

    That's it. The new setting will be your new maximum GPU frequency.


    Below there's another option called "GPU Governor". Just tap on it and select your prefered one.

    NOTE: If you want to track current GPU frequencies and watch governor's behavior, just switch to Trickster's "Informations" - Tab and watch the frequencies clock.




    1.5 How can I use Gamma Control?


    What is gamma? The gamma setting sets the color range for the screen. You can compare it to the contrast. We all know that the touchscreen eats most of the power compaerd to all other components in a smartphone! A lower brightness causes less power consumption and a lower gamma or contrast range alos helps a little bit to save power.

    In this kernel you can choose from a range of "5 - 10" while "5" is very bright while "10" is very dark. The default setting is "5" BUT CAUTION: Trickster Mod will display a range of "0" to "10" and the default setting will be shown as "0". This is caused by the fact that this feature was ported from the Gnex device where you can choose from a higher range. The only sideeffect is that the values "0" - "5" won't show any difference.



    How to set the gamma value?

    Well, once again open Trickster Mod and swipe to the tab on the right end. Just select your preferred value by using the slider.


    Alternately you can use sysfs by terminal or adb:

    OMAP Gamma interface:

    echo i > /sys/devices/platform/omapdss/manager0/gamma

    Replace i with 0-10 of your choice.






    1.6 What is "Battery Friend and how to use it?


    Battery Friend is a simple toggle (ON/OFF) which sets your device into a battery friendly mode without the need to play with all settings in Trickster Mod /sysfs until you find a good setting. In fact it does the job for you.

    What does it affect?



    NOTE: Doesn't lock anyx frequencies anymore!


    • locks dynamic Fsync enabled
    • locks Fsync disabled
    • Doesn't allow any OC (Live OC will not have any effect, Core OC is not allowed in this kernel)
    • Increases the dirty ratio interval to 90% (starts working at this value)
    • Enables Dynamic Hotplug: This doesn't allow hotplugging during device is active - and it will always turn CPU1 OFF during suspend! It also prevents from conflicts when user uses a hotplug governor (which isn't a good idea though) - but hotplug governors are causing higher battery drain!
    • Dynamic Page-writeback always enabled


    How to toggle Battery Friend:

    For now the only way is via terminal, adb shell or root explorer (text editor)

    For terminal and adb:

    Code:
    echo 1 > sys/kernel/battery_friend/battery_friend_active     /* Enable  */
    echo 0 > sys/kernel/battery_friend/battery_friend_active     /* Disable */

    For Root Explorer
    1. Open Root Explorer
    2. Navigate to sys/kernel/battery_friend/
    3. Open "battery_friend_active" with Text Editor
    4. Change "0" to "1" and safe the file to enable
    5. Change "1" to "0" and safe the file to disable



    1.7 Suspend Governor Control (CURRENTLY DISABLED)

    Suspend Governor Control is a kernel module written by me. You can use it to set your preferred Screen-Off-governor.
    For now it's only supported by sysfs (Trickster Mod will support all my current and upcoming features as soon as it gets updated with its new UI mode!


    How to set suspend governor

    Open a terminal or use adb shell

    Code:
    su
    echo "x" > /sys/kernel/suspend_gov/suspend_gov

    Replace x with one of these values:

    0 = Ondemand
    1 = Ktoonservative
    2 = Conservative
    3 = OndemandX


    NOTE: No matter what governor you use for suspend mode, if Battery Friend is enabled the second core will be turned off during suspend!



    1.8 IVA Overclock

    What is IVA OC?

    IVA OPPs are controlling the CPU load for sound events. It could be useful (in some cases) when you get sound related laggs. Just set the maximum frequency to highspeed. This will allow more CPU power for sound events but also will cause higher battery consumption.


    How to use IVA OC?

    If you want to check the current IVA frequency. Just type in Terminal or ADB:

    Code:
    cat /sys/devices/system/cpu/cpu0/cpufreq/iva_clock

    You will get an output like this:

    Code:
    132 Mhz


    2. You can whether enable IVA highspeed: 130 - 430 Mhz ["1"] or enable IVA normal speed: 130 - 332 Mhz ["0"]


    320 Mhz max: echo "0" > sys/devices/system/cpu/cpu0/cpufreq/iva_freq_oc
    430 Mhz max: echo "1" > sys/devices/system/cpu/cpu0/cpufreq/iva_freq_oc




    1.9 DPLL Cascading

    DPLL: Davis–Putnam–Logemann–Loveland (DPLL) algorithm

    To get more info about this please see wiki
    But to sum it up shortly: It helps to use/stream media (music) in a low power mode.


    NOTE: DPLL Cascading will be available to be switched easily via Trickster Mod App soon!



    How to switch DPLL?

    DPLL is ENABLED by default!


    Open Trickster Mod -> Speicific Tab --> DPLL (soon)


    sysfs:


    Turn off:


    Code:
    echo 0 > /sys/kernel/dpll/dpll_active



    Turn on:


    Code:
    echo 1 > /sys/kernel/dpll/dpll_active




    1.10 HDMI toggle

    Some users are facing a RAZR-sepcific problem: HDMI cable is detected, even though there is no cable plugged!
    Therefor I included a toggle to switch HDMI wether ON or OFF. Additinally there's an init.d script included within the AROMA Installer you can select during the installation of JBX-Kernel.

    To enable/disable HDMI on-the-fy:

    sysfs:


    Turn off:


    Code:
    echo 0 > /sys/kernel/hdmi/hdmi_active



    Turn on:


    Code:
    echo 1 > /sys/kernel/hdmi/hdmi_active




    1.11 Intelli-Plug

    For intelli-plug hotplugging is now only allowed when the device enters sleep.

    To enable hotplugging universally just change the value of the following entry whether to 1 (on) or 0 (off):


    Code:
    sys/module/intelli-plug/parameters/int_hotplug




    1.12 Dynamic Fsync VS. Asynchronous Fsync

    * HTC's Asynchronous Fsync and Dynamic Fsync:

    Asynchronous fsync (called "afsync" or "async fsync") from HTC is ported into this kernel. By default it's enabled and dynamic fsync is disabled (and as well it isn't needed anymore). But just to test a little bit around to see which one of both features is the better one - for battery & performance. But currently Tricktser Mod doesn't support a toggle for afsync, so I had to find another way to use Trckster. Finally I did it like this:

    The dynamic fsync toggle in Trickster Mod is now serving both functions - the dynamic fsync AND the asynchronous fsync! How? By default Dynamic Fsync is disabled, and Afsync is enabled. If you now enable Dynamic fsync using the toggle, Afsync will be automatically disabled, so both functions are not conflicting each other - and this way we have a working toggle for both of them.


    2. If anyone has the following issues:



    Issue

    Media Process FC
    No SD-Card in File Explorer
    My CPU Settings (frequencies, etc) won't be saved (it sets itself back to Kernel default after screen off)
    My phone freezes/reboots always when I try to set options in Trickster Mod
    The device is lagging very hard
    Solution

    Media FC: Open App settings, head to "Download Manager" and "Media Storage" and hit the "delete data" button. Reboot. Now it shouldn't give any FCs anymore and after a little bit of waiting it will find all Media (Pictures, Videos, etc..)

    No SD-Card: Reboot into recovery, go to "Mounts & Storage", tick "mount int" or "mount ext".

    USB: Make sure the screen is ON while plugging the cable in.

    CPU Settings: This is a bug which cannot be solved at the moment. Temporary solution: In Trickster Mod just activate the "Frequency Lock" and your settings will persist.

    Trickster Mod:: Open App settings, Trickster Mod and select "uninstal updates". Now it should work.

    Crashes, Freezes, lagging, something doesn't work, etc

    There are too many reasons which could cause crashes! So here is a checklist for you to look for. Check each point and try the following workaround:

    - Your rom has CPU tweaks (e.g. Kernel modules, init.d folder, etc)
    - You have set custom CPU settings (e.g. custom frequencies with apps like No-Frills CPU Control, Set-CPU, Antutu, etc...)
    - You have undervolted too low
    - You have overclocked too high
    - You have applied higher "Core OC" value in Trickster Mod App
    - You are running any other kernel tweaks which are regarding to the CPU and/or performance (e.g. Kernel modules by Whirleyes eventually set by init.d, etc..)
    - After setting some settings (e.g. in Trickster Mod) your device doesn't boot anymore
    - adb doesn't work / shows only "device offline"
    - You are facing hard lagging

    If any point here matches your setting, please revert from it:

    - Remove any CPU init.d script from /System/etc/init.d
    - Uninstall any CPU controling app (e.g. Set-CPU, No-Frills, etc..)
    - Remove all extra kernel modules from system/lib/modules (e.g. cpu_control.ko, cpufreq_smartass2.ko, etc..)
    - Unset any custom settings from any other kernel / CPU - tweaking app which is NOT Trickster Mod
    - Maybe your governor causes issues. Hotplug is know for bugs at the moment...I'm going to fix it..
    - NEVER set your CPU Settings (e.g. in Trickster Mod App) on boot!!!! - before you aren't sure that your settings are safe!!!

    - You may flash the kernel again after reverting related settings

    - to make adb work / show device online, download latest SDK platform-tools and confirm access on device (4.2 security feature of Android)

    - Don't use any task killers, memory killers, seeder apps! They may conflict with the kernel/Rom settings.


    If none of these suggestions work for you your rom may be incompatible. Please report it here that I can add the rom to the list of imcompatible roms


    If you have any issue, please read this:

    First check:


    - is it really a kernel issue?
    - did I see this bug with the roms original kernel?
    - what are the people in the rom thread saying?
    - what are the people in the kernel thread saying?
    - can I find this issue on a bug list?
    - how about my settings? Is it my fault it crashed?
    - can I find something useful in the kernel FAQ?
    - Is it maybe a well known issue and can be solved
    withing seconds? Just like wifical.sh?
    - Where to repeat that issue? Rom or kernel?

    I know it's sometimes difficult to track the issues, and we can't know for sure if it's caused by the rom or by the kernel, but if you try at least to get some information you might find an answer sometimes. If you are able to understand logs, you may report whatever you find.
    All this helps to keep the threads more clear. Thank you.

    I would just like to pause and acknowledge the great progress that has been made and ask for a moment of thanks for the hard working developers. In just a few months we went from officially being dropped from CM support, to being reinvigorated, launching a successful test build of android 4.4 and finally renabling CM 11 nightlies for all OMAP4 motos. It wasn't easy but we got it done. And now we have a fairly stable ROM and for the first time in awhile working 1080p video recording and playback. I couldnt be more proud of the work we've done and I just want everyone to realize how much work and effort has gone into it. Many people gloss over what works and doesn't work. But the untold stories are the hours of code review and testing that we go unpaid for using our spare time to bring these great updates to our devices long after official support has ended. I am proud to be a part of that and see the RAZR line live on and you can bet I will still be here pushing for Android 5.0 ;)

    Nice to get some understanding for our work. I totally agree! Most people don't realize how MUCH work it is to develop - whatever it is. I know about people like Hashcode, alteredlikeness, ravikiran, rgocal, and many many more... How they spend not only hours but whole days and nights, radical heavy development just until the stuff gets functional. And also how we sometimes chat a whole night, share knowledge and work together. E.g. Hashcode who has a family and though spends weeks for our device, and he's always helpful and answering all my questions and check my code for fixing if I ask him. Even though he stated to drop OMAPs, what he didn't yet actually! THX!
    We all sometimes spend more time for Android than for our families and our jobs in real life! And we don't take money - but support is always well appreciated!

    Also big thanks to others like Artur, vathazka and more who are serving the community very well and spend their time for us!

    It world be nice to see more people collaborating with us and learn about development. If you ask me, I'd like to see more people starting to learn about kernel development :D
    If there were someone familiar with kernel, I'd like to continue what Hash already started: updating the kernel to 3.0.88!

    Thanks to all devs, modders, themers, testers, and the whole community!

    Now there comes a lot of great stuff for you guys!

    - kexec stock patch
    - cdma patch (kexec stock)
    - gsm patch (kexec stock)
    - Miui V5 (Kexec)
    - Catalyst v3 (kexec)
    - more....

    You probably ask yourself "why, from where, wtf??" :D

    Well, today we managed it to boot catalyst 3 on kexec! And I finished a patch for cdma/gsm. All users, no matter what stock kernel they run, can now run all stock based Roms (and of course cdma ans gsm Roms will work for both).
    There is an almost finished Miuiv5 build ported by me to RAZR.
    The best project Catalyst 3 will be released soon too.... Enjoy the upcoming weeks ;)


    Edit: forgot to mention that JBX-KERNEL will be available for stock Roms soon!

    Good news!

    I just received the RAZR MAXX from Crumplet - MANY thanks, mate!!

    Now I am going to start uipdating kernel sources and other stuff up to Android 5.x, then after a few days I think there will be a new JBX version available for latest roms. ;)
