After days of trying to get multichanel sound from cheap android 10 box – I end up with LibreElec on PC.
Just downloaded USB Creator from their site, chose Generi Legacy image, boot from it and it WORKS like a charm.<\/p>\n\n\n\n
Litle bit strugling was to force KODI to hbe shown on monitor connected via HDMI on Lenovo notebook. Desktop PC does not have this problem, if only one display (TV) is connected.<\/p>\n\n\n\n
This is the way how to force LibreELEC to use output of lenovo T570 notebook:<\/p>\n\n\n\n
Connect to LibreElec dedicated PC via Putty (you must enable SSH during libreEelec first boot)<\/p>\n\n\n\n
Some testing commands:<\/p>\n\n\n\n

It was chepa Allwinner based Android 10 box from Aliexpress. I gave up. Maybe I’ll try to write an android app to force linux ALSA sound driver to be visible for KODI.<\/p>\n\n\n\n

Long story short, did some testing, and with a few ADB shell script commands you too can unhide the MANUAL SurroundSound setting’s UI toggles in the MECOOL KM7 and probably other ATV11 devices as well.<\/p>\n\n\n\n
!!!! First, inside the DISPLAY_&_SOUND settings under ADVANCED_SOUND_SETTINGS option turn-OFF the S\/PDIF output, and note the Formats is either “Automatic” or “None” – and after you input the script cmds neither option will be chosen.<\/p>\n\n\n\n
All works well in passthrough including kodi, netflix, amazon prime and apple tv but when I restart all is lost<\/p>\n\n\n\n
so I am using tvQuickAction to send ADB Shell commands: settings put global digital_audio_format 2 settings put global encoded_surround_output 3<\/p>\n\n\n\n
You can also use adb on boot apk (https:\/\/xdaforums.com\/t\/app-no-root-adb-on-boot-run-adb-commands-at-boot-automatically.4368281\/<\/a>)<\/p>\n\n\n\n
write exactly this to the apk:<\/p>\n\n\n\n
sleep 20; settings put global digital_audio_format 2; settings put global encoded_surround_output 3<\/p>\n\n\n\n

- DTS_HD = 8<\/li>\n\n\n\n
- DOLBY_TRUEHD = 14<\/li>\n\n\n\n
- E_AC3_JOC (DD+Atmos) =18<\/li>\n\n\n\n
- There are way more ENCODED audio codecs in ANDROID’s main source-code that can be sent via passthrough, but they need to have a corresponding DIGITAL entry in Amlogic’s source-code to work with an Amlogic SoC. But they are just not all populated in Amlogic’s JAVA. But personally, I believe the real reason that HD-Audio codecs can’t be sent via passthrough is Amlogic’s Linux Kernel is still broken for Android 11, but there is hope that it might be fixed for Android 12.<\/li>\n<\/ul>\n\n\n\n
After entering the above ADB cmds, I recommend doing a device REBOOT, and checking that the settings persisted by connecting ADB again and scrolling through the GLOBAL settings list.<\/p>\n\n\n\n
NOTE:<\/h6>\n\n\n\n
I have NOT tested these Audio settings extensively with every streaming app available, I tested with Amazon PrimeVideo and DolbyAtmos worked and was sent via Passthrough, so was happy and deemed my mini exploit a success.<\/p>\n\n\n\n
Don’t have a Netflix sub personally, also KM7 not Netflix certified, but if somebody with the Realme 4K stick wanted to try inputting these settings with ADB, Netflix may still not passthrough ATMOS unless inputting two further ADB settings:<\/p>\n\n\n\n

Are you still using same SPDIF cable with AVR?<\/p>\n\n\n\n
Cause your Audio problem can only potentially be solved with some ADB shell scripts.<\/p>\n\n\n\n
Netflix needs this setting shell command to be set for SPDIF passthrough:<\/p>\n\n\n\n
