@microkatz Could you take a look?

Any update here?

I found a similar issue 627. So, I tried the latest version 1.2.0-rc01, but still AudioTrack write failed and no audio can be heard after setPreferredAudioDevice. The issue still exists.
Then I tried another way.
I added the code 3742f6b to the release branch. The log still shows AudioTrack write failed, but audio can be heard after setPreferredAudioDevice. The log shows it is using deep-buffer-playback rather than compress-offload-playback after setPreferredAudioDevice.

@microkatz I hope this can provide you with some useful information.
