Hi Sangmin, After several tests, I think the root cause is: When changing audio routing, we will notify "btvservice" to stop sending audio data and mute then unmute BT sink. And if we unmute BT sink too soon, the audio buffer will be bothered by remained BTV audio data. So I add a delay after notifying "btvservice" to stop for waiting the audio buffer cleared. And because we don't know how long "btvservice" will take, I test for many times and find that 100ms delay will be fine. So finally, my fix is: add a delay(100ms) after notifying "btvservice" to stop. Thanks~ Sam |
