I use Chromecast Audio (into powered speakers) + Poweramp app to play the music files on my phone. Yesterday morning it was working fine (as it had always for 3 years) but in that afternoon, it suddenly stopped functioning.
By "stopped functioning" I mean:
I tap the Chromecast icon on the main screen
I select Chromecast Audio device as cast destination
The Chromecast icon changes to "connected" state (Usually I can almost immediately start casting music at this point)
After 1 minute, a notification sound comes from the speaker. The Chromecast icon changes back to "disconnected" state.
Me sad.
Things I have tried so far:
Turned off and on (to no avail) the...
phone
wifi router
Chromecast audio
Google home mini (just in case)
Tried casting to Google Home mini to see how that would go: The same phenomenon as Chromecast occurred (1 minute nothing then "disconnect")
Uninstalled and reinstalled Poweramp (and Unlocker): problem persisted
Tried mirrorcasting (Android's function that mirrors whatever sound your phone makes to Chromecast): this worked no problem.
Installed different music player apps that have Chromecast functionality and checked if Chromecasting worked on them:
PlayerPro: casting successful
HiFi Cast: casting successful
Installed Malwarebytes and did a full scan: nothing found
So, as far as I can tell, Chromecasting via Poweramp is the only thing that seems to have a problem.
I would greatly appreciate it if anyone could suggest anything I could further check or try.
edit: oops, I didn't think this was a bug so I didn't check bug reports. Thank you for moving the topic.
