Becomes unresponsive after some days

[timgoeller]

After some days, lovspotify becomes unresponsive for me. When I want to play music, the app and the web interface say it's playing the song, but it's not. Also, I can't stop the song, or even open the song details on the app. I can still skip songs in the web interface (but it won't play the next song either). This happend every 5-6 days. The last times I got it working again by just restarting the pi or the service, but that doesn't seem to do the trick this time.

(I'm using a Raspberry 3 B+)

Hej Tim ,

Could you add some logs when that happend ?

Please open a console and enter

journalctl -u lovspotify

This error appears in the log. Seems to be some audio issue, though I didn't change any settings:

The issue is that the Mixer Headphones [plughw:1,0] is disappearing. You could try to use Headphones [default] instead of Headphones [plughw:1,0]

[spocon]

the issue is the linux system together with Java which lovspotify is running in . Java itself provides the Sound Mixer. https://docs.oracle.com/en/java/javase/11/docs/api/java.desktop/javax/sound/sampled/Mixer.html

You could try to ask the maintainer of the package librespot-java , https://github.com/librespot-org/librespot-java

I replaced the "Headphones [plughw:1,0]" in mixerSearchKeywords with just "Headphones", that worked!
