Fixed: Miui V7: Bluetooth A2dp Bitpool Too Low: Poor Bluetooth Audio Quality

[Ludovic815]

Hello, (my phone is a xiaomi MI2S running MIUI 5.8.20, but this bug may concern also other phones)
When listening music with my bluetooth headset or with the xiaomi bluetooth speaker the quality is very poor.
The problem seems to be related to a wrong bitpool in the a2dp library in /system/lib/hw/audio.a2dp.default.so.
In MIUI V6 I was able to use a workaround: replace audio.a2dp.default.so and bluetooth.default.so with the libraries from a non-MIUI rom (I used mokee os for MI2/S) but now, when I use these files, com.android.bluetooth force closes.

The logcat is available here: http://ludo.lehmann.online.fr/Log.txt

Here the same problem, my phone is a mi3 and the bluetooth audio cuts every certainly time, and the quality is very poor too. Please let me know if you found a solution.

I found a bug report here:
http://en.miui.com/thread-50604-1-1.html

But it is not fixed yet, will it be one day?

I think we will have to find a solution ourselves, because xiaomi just doesn't care!

I've actually noticed that Bluetooth audio quality is way better. I forget which update in MIUI6 that it improved.
