The volume control stays at full no matter what I set the volume to when I play a movie with the plex player on the android app. When i restart the device, it fixes the problem until I fast forward and the volume jumps up again. The device is a lenovo tablet running crdroid. Also when I play the videos through and external player like vlc, the volume is fine.
I found a few people describing the same problem but I have not found a solution:

On my phone (running Android 12), however, this problem does not seem to happen at all.
Any ideas?
