Android will pause playback (but not disconnect) after a while in the background, even if battery optimization is turned off

Zhiyu_Wan · November 5, 2023, 1:18pm

Description and Steps to reproduce

Open AudioRelay on windows (as server) and android (as player). On android 14, give audiorelay all permissions. Turn on the software’s self-start and turn off battery optimization. Play a video on windows. Both of them work fine at this stage. I can hear the sound.
On windows, pause the video. On android 14, switch to other apps and use them for a while. Wait for about 3 minutes.
On windows, play the video again. You can see that the windows app and android still running and connecting. But no sound is playing by android.

Devices

Device A:
Windows 10
AudioRelay 0.27.5

Device B:
Xiaomi 13 Pro, MIUI 14, Android 14
AudioRelay 0.26.1
