Audio [MOD][2016.02.15] - HK - BS - JBL / Aroma Switcher 5.0.3 / ADSP v62.2.2

Features:
- Flash the Harman/Kardon function of the Harman/Kardon Sprint M8 to stock GSM, VZW, and Sprint phones
- Flash the BoomSound function back to all phones, make the Sprint H/K Phone a BoomSound phone (theoretically working, untested).
- Flash the JBL Audio function of the Butterfly 2 to stock GSM and Sprint phones (much like H/K, mostly a cosmetic difference)
- Each function being selectable in a neat Aroma UI, flashable via recovery.

Requirements:
- S-OFF is mandatory - do NOT try to flash the ADSP to S-ON Phones - the risks are unexplored. Damage might be inflicted!
- S-ON and S-OFF Harman/Kardon Phones can use this mod too to restore their HK functionality on ROM's that only come with BoomSound like e.g. ViperOneM8!
- Recovery to flash: needs to be a current TWRP! NO Philz, NO CWM please!
- HTC Marshmallow Sense ROM! No AOSP, AOKP, Cyanogen, GPE or whatever Senseless...

Changelog:

Tested on: see post #2!

Known issues:

• On 5.0.x: With ViperOneM8, there is a sporadic Settings-FC when enabling Bluetooth for the first time after changing to Harman/Kardon

Some release notes:
- People on Lollipop ROM's please refer to 4.3.1 Version! 5.0.x is Marshmallow only!
- Harman/Kardon ADSP 6.2.2 seems to be serving BoomSound just as well, again. So, you actually only need to swap to HK ADSP once, and leave that one in, even when going back to BoomSound.
- The new 5.0.x switcher works with Marshmallow files for GSM and Sprint. On VZW it works with ported MM ROM's, but not with older LP ROM's.

Additional Info for interested people
The logic of the File setup can be seen here: https://docs.google.com/spreadsheets/d/1xxXC00mpjq8cBgZUz0jOLx20qrC5W4JY0ZrbbBmG81M/pubhtml It has been updated to reflect the current 5.0.0 (Mod) version.

A little disclaimer:

Download:
Marshmallow version 5.0.3 (or check DevDB download tab)
Lollipop Version 4.3.1 is here or check downloads tab of DevDB.

Optional Kernel: (Marshmallow only)
This will take care of any issues with High BitRate Flac audio files that don't play properly.
This is a stock Harman Kardon kernel which uses the AnyKernel method of install, so it won't touch your current ramdisk.

Viper4Android Aroma Installer

Ok, so I have seen users wanting to utilize this HK/BS/JBL Audio Mod, as well as Viper4Android.
I completely understand why, as they both have their advantages and together they can produce some great audio.
So to help with compatibility issues, I have redone a Viper4Android Aroma Installer, that I had put together previously.
In the V4A installer, I have included options for compatibility with the Mods in our HK/BS/JBL audio mod posted in this thread.


Viper 4 Android

Aroma Installer for HTC M8
UI Options:
- Default UI
- Dark Material UI
- Lite Material UI
Compatibility Options:
- For use with Harman Kardon
- For use with Boomsound
- For use with JBL Audio
______________________________

DOWNLOAD:
ViPER4Android_FX_v2.4.0.1_Aroma-Installer_santod040_v3.05

To install this V4A Aroma Installer:

• First you should flash your HK/BS/JBL option of choice, from the installer in the OP.
• Then flash the V4A Aroma installer, which I've linked below and choose your current Audio choice in aroma during the install. (HK/BS/JBL)

This will give you optimal audio configurations, for use together with the Mod in the OP.
Without having to delete, remove, or compromise any of the audio libraries that should go along with your existing audio.
Some of the other solutions out there, delete important audio configs, or chop them up in ways which are not in line with the stock HTC audio configurations.
This will give you the best of both worlds, when used along with the Switcher in the OP.

Notice to everyone:

I would like this thread to be kept short and simple. It only serves the purpose of "uncluttering" the original HK Audio Mod thread and should help get this Aroma based mod some proper discussion without me feeling constantly like i actually hijacked another thread.

I will ask other members to refrain from discussing audio quality in here as best as you can, because that is pretty pointless with this mod. The files are mostly set and not much we can further find out about the composition of the Harman/Kardon functionality. Modifications to sound-relevant files are NOT done here. All HTC standard files.

What i want to discuss:
- Scripts (Aroma/Shell)
- File composition (did you really find that one file i missed or are you audio hallucinating)
- Other aspects of the mod.


HOW TO WORK WITH DEV DB
In order to have this clean and tidy, XDA had the brilliant idea to introduce the "Dev DB" feature. That is the black bar at the top - it has several headers.

Disucussion - this main thread. It is not for Off-Topic, obviously, but it has a broader spectrum.
Screenshots - i will not be using that!
Downloads - thinking of putting all downloads there
Feature Requests - feel free to drop feature requests here, yet be aware there is not very much to be added.
Bug reports - in future, please drop PROPER bug reports there ("It doesn't work" doesn't count as one!) Logfile, getvar all output, ROM version, recovery version.

In order to achieve this handling, i might be reporting a fair number of posts, so please don't feel offended, just accept that i might not want every discussion in here.
Tapatalk Users: please be aware that some or all of those Dev DB features might not be available for you. I believe this is, for now, only accessible through the web interface.

First, some basics . . .
This is what BoomSound looks like in Settings:

The adsp version can be found in the bootloader (HBOOT). The current BoomSound adsp information can be found below:

This is what Harman Kardon looks like in Settings:

The current Harman Kardon Edition adsp information can be found below:


NOTE: The adsp version can also be found in /firmware/adsp in the file adspver.cfg. See below:


So, what is this HD Audio support in the kernel everyone's talking about?
In kernel source, the HD Audio flag can be found in sound/soc/msm/Kconfig. According to the Kconfig for the "HD_AUDIO" flag:
This additional codec support, along with the HK files allow 24-bit, 192KHz FLAC file playback with the stock HTC Music app.

Most (if not all) custom kernels have this flag enabled. My kernel is just here as an option for people that want a close-to-stock alternative with it included, without all of the extra "bells and whistles" that the other custom kernels feature.

Current Version: BeyondStockᵀᴹ M8 Kernel v3.2.1

Features:

• HTC system write protection disabled
• Dirty file record disabled
• kexec-hardboot for MultiROM support
• HD audio support
• NTFS RW support
• F2FS support (added with v3.2.0)
• Ondemand governor set as default
• Compiled with Linaro 4.9 Toolchain (optimized for cortex-a15)

Kernel Source (github)

Is my recovery really that important? Why can't I just use PhilZ, CWM, etc. instead of TWRP?

Well first of all, TWRP is the most actively developed of the custom recoveries, with the most robust features. PhilZ and ClockworkMod are no longer being maintained. I also know for a fact that TWRP for the M8 works on all M8 variants, regardless of Carrier, and was built using the latest Lollipop kernel and with Lollipop source. This makes it the most compatible with this mod, which is made for Lollipop.

The official TWRP works fine for this, but I also have a custom build of TWRP for M8, which uses the stock kernel module for exFAT support. This seems to be more reliable than TWRP's exfat-fuse implementation, and allows support for AROMA File Manager as well. NOTE: Starting with 2.8.6.0, my TWRP build uses the Samsung Open Source exfat-nofuse implementation, rather than the stock module, and adds F2FS support.

My TWRP thread is here.

This is my download folder with my latest versions (current version is 2.8.6.0).

I also HIGHLY recommend this theme for TWRP. It makes using recovery a completely new experience .
