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

I can confirm this with both my poco f4 gt and xiaomi pad 6s pro. Both stop playing audio from my pc after some silence on the windows server. Even when streaming from one android phone to another.

Another detail to add is this only happens when the android app is in the background. If the app stays on the foreground, it continues to play even after a long silence on the server.
