I am not sure is this is a big but i have just encounter this issue.
I have the plexamp on my samsung phone, and it is able to stream or play any download audiobooks with no issues.
But yesterday was i was playing a audiobook my phone rang so i moved away from plexamp to answer it. Great the plexamp stop and i was able to answer the call. But when i return back.to the pleamp. I discovered that the volume had halfed and also that i was not able to.stop it as the play/pause button was flashing.
The only way i cound stop this is by rebooting my phone.
