After connecting a bluetooth headset and using Firefox (115.0a1 (Build #2015950435), 1d9511bcc3 + this version so far) to play online video is obviously lagging, not audio and video is not synchronized, is to play a moment to get stuck in a frame like this. My own troubleshooting revealed a problem with Firefox and the encoding format selected for the headset. Currently 1 the problem is only in bluetooth audio encoder selection acc (lhdc also have the problem but the symptoms are not as serious as aac) and triggered in firefox, other browsers can not be reproduced, test redmi k40 and xiaomi 13p also can not be reproduced. 2 after the screen recording is turned on, the problem is obviously lagging. 2 The problem disappeared after turning on screen recording, the screen recording parameter is 1280x720@60 at 32mbps, and the audio source is recorded in the system. Play the video first and then open the screen recording lag disappeared, first start screen recording after playing the video lag does not appear. And no matter what kind of situation screen recording stops lag recovery.

Hi

You appear to be using an older version of Firefox for Android. I recommend updating to the latest version from the Google Play store.
