Dear developers, please, fix the sound bug in 3d games, after watching ads in the game and returning to the game, the sound doubles, after still watching the ads, the sound triples and slows down a little, you can hear a quiet intermittent crackling in the speakers. After a few, it looks like a multiple echo. On LineageOS 17, the same. Both are based on the 10th android. On line 16, everything is fine. Tested on three t320 devices. I re-flashed it several times.

First Check your Router Settings for your Wifi 802.11 Mode.
Each Channel 2.4Ghz and 5Ghz has different Mode for device.

on your Router Settings should be accepting.
802.11 B/G/N ---- 2.4Ghz Wifi
802.11 N/A/AC/AX --- 5Ghz Wifi


You should change your Router 5Ghz To Legacy Mode Channel.

SM-T320 uses Wi-Fi b/g/n/a/ac
802.11 2.4Ghz = b/g/n
802.11 5ghz = a/ac

If you are near the Router like 200 feet, You use 5Ghz.
Already fixed it, it was the drivers that I was using.

After going back to the old ones, working perfectly

hello, just updated ColtOS 6.0 to 6.5 and wifi is unrealiable. It disconnects all time .
Did a clean install ( wipe, format, install) and nothing.
Also could not use any Gapps (BT or GApps) as it reboots consistently.
Any thoughts?

Hi, I just flashed the ROM.
Movies coded with x265 don't work, and it seems I cannot install codec or any other player (like VLC): correct?
Thanks.

Nice!
Could you please share how to do that for me and all other mortals with the same problem but low on hints?
Please backup your ROM before you flashing this zip file from TWRP Recovery.

This worked for me aswell! Thanks!

I'm getting reboots if I try to change from charging to file transfer when the Tablet is attached to a PC via USB.
Does anyone else has this problem?

Just a quick update I fixed Miracast and will be available in the next build, currently working on selinux enforcing (just finished up a million selinux rules, everything is working but needs a few users to test before I make it final), I may have a beta for everyone to test tonight or tommorow, it will require a clean flash though.

Also sorta fixed MHL support (anyone still use MHL?), it does have a bug where it will freeze display if screen turns off though, but works fine as long as the display is on...

Increased performance quite a bit too.

Next update will have some new wifi changes, but it's hard to determine since wifi is working ok here, using iperf3 I get around 20mb/s on 5ghz and no disconnects, and 2ghz works ok, it could be a region issue but without logs it's hard to tell.

if you could provide a logcat it would help find the cause.

    Seems to work ok here, i'll do some more tests though to see if I can break it on my end.

    I am getting the next update ready (probably sometime in july 5~10) , let me know if you have any suggestions to improve this rom.

    Upcoming fixes
    1. wireless display audio issue is completely fixed. (tablet will be muted, sound will output on tv only)
    2. minimized debug info and include the art release runtime.
    3. rom is official .
    4. OTA updates, however it would seem our official twrp doesn't support OTA, it just reboots to recovery and doesn't install the zip .....
    Note: I can include OTA support but when it reboots to recovery you would have to manually select the update from /data/colt_updates/ and install it... this is a TWRP bug not my fault.

    What do you think about OTA,? also I am looking for feedback on the microphone changes, did it fix the issues / make it worse or improve at all?
    4
    New build up, lots of fixes.
    ColtOS-v6.1-mondrianwifi-20200616-Unofficial.zip
    MD5: b4c2b5fa4bb31977b127dca20c02254c
    06/16/2020
    Device Tree Fix-ups
    Miracast is partially fixed, I am still trying to fix the audio issue, but for now it can cast to tv, if you need to mute the audio I suggest plugging in headphones turning volume up then connect to a miracast device and audio should be output on tv where you can adjust volume levels.
    Microphone(s) should be improved, let me know if they are too loud or still not working properly .
    Smart Charging is partially working but I only included this as a test, it will turn off charger at full trigger level (this prevents battery from constantly trickle charging or if the battery has problems reaching 100 we can stop it at 80% for example, the main issue is when the battery depletes past the preset low trigger it's supposed to charge back to the full trigger for proper behavior, our device is broken in this respect, so I disabled the low trigger in this build, so just be aware once the charging is stopped it will run on battery until the device shutdowns / reboots or is re-plugged in...(*only if smart charging is enabled)
    AOD - Fixed, I set it to the lowest brightness. (this device has a power hungry LCD), Supported modes: Always On, Charging Only & New Notifications).
    Fixed button mapping, it was showing a non existent 'menu' key, now it has been properly mapped to the recent/overview key.
    Fixed notification permission access, "this feature is not available on this device ",
    Fixed draw over other apps permission.
    Fixed other permission popup dialogs.
    Fixed Split-Screen Note: (you need to map the split-screen action to a button first, this can be done under "Settings -> ColtEnigma -> Buttons -> Buttons -> (select a button's long press or double tap action), Custom Action -> Split-Screen."), or under the recent switcher press the middle app icon and select 'Split-Screen'.
    Removed Notification LED settings since our device doesn't have a notification LED.
    Many more fixes, it should be a lot more smooth and responsive now.

    Clean flash is recommended but you can try dirty.

    Edit:
    I fixed the Wireless Display Audio issue
    4
    Speaker volume really low on 7/14 build for me.

    Thanks for the report, I will fix it in the next update, or if you have root / twrp access with attached file you can replace the file under /system/vendor/etc/mixer_paths.xml to restore the volume levels.
