Bluetooth TWS device can not play audio, keeps disconnecting-reconnecting [lineage-17.1 | kernel build 2021-04-01] #18

Closed dibyanugraha closed 3 years ago

dibyanugraha commented 3 years ago

Describe the bug Bluetooth TWS device can not play audio (tested with Edifier X3). Bluetooth keeps disconnecting then reconnecting if audio forced to play (audio is automatically stopped)

To Reproduce Steps to reproduce the behavior: Pair TWS bluetooth audio device, play any audio using any music player (I used Musicolet), error occurred.

Expected behavior TWS paired bluetooth device play the audio without any problem.

Environment (please complete the following information):

Additional context No custom kernel, nor Xposed. Almost vanilla from scratch - clean flash, flash latest kernel, install magisk only to record log using MatLog.

Notes I noticed several custom roms had the same problems (?) from simple google search. I found some makefile includes libldacBT_dec in the PRODUCT_PACKAGE section -- it's missing here. Do we need specific vendor blob in order to build that?

Unfortunately, there is no official way to build libldacBT_dec in either AOSP or LineageOS, and most devices do not have this lib in their vendor proprietary files. I also searched for it but got few valuable results (like this one). I have no Bluetooth TWS devices to have a test, and most custom ROMs on Mi-4c should have similar audio issues (especially after Android 10).

Is this problem also happened to normal wireless earphones? Also, could you try playing an audio file twice (start → stop rather than pause → play again) before connecting to TWS devices and continue playing?

dibyanugraha commented 3 years ago

Yes the problem persists in any case. If I start playing the audio using speaker, it plays normally, however when I paired the tws device, the audio from the speaker immediately stops, the tws automatically disconnects. It will reconnect eventually, but if I keep try play the audio again, it will disconnect again.

I think the link that you mention to Lineage gerrit is broken. Could you please take a look again?

Maybe some audio changes after Android 9 break the compatibility of the old vendor blobs on Mi-4c. At least, I remember that my device worked properly when connected to an old Bluetooth speaker using SBC codec. The link has been updated (there was an extra "." at the end).

Well it's indeed unfortunate if the problem is on the vendor's blob. But you could please create a test build where this is enabled?

https://gerrit.aicp-rom.com/c/AICP/device_htc_oce/+/97280

I saw similar patch is applied on sd660 tree (redmi note 5, whyred) and redmi-mt6768 (redmi note 9, merlin). If it's somehow "force" create that file -- although perhaps unusable, or broken -- at least we both know that maybe it's impossible to have BT audio on this post Android 9.

There is no make target called libldacBT_dec, so nothing will be built after all. I tried to add it to device.mk and rebuilt the ROM, but I cannot find libldacBT_dec.so in system partition (like picture). image

dibyanugraha commented 3 years ago

I understand. Thanks for testing it. Really sorry for wasting your time. Anyway, since you mentioned it, I realized indeed the system audio decoder is broken. I play using Musicolet which has its own decoder. When it uses its own decoder, the audio plays. But when I switched to system decoder, it won't, no matter what I did. Same when I used the default Lineage music app, the audio won't play. I play aac/m4a file.
