[PROBLEM] Spotify - no Sound on the speaker

[gntng]

Try raising the volume on the clients.

Interesting, this is not possible. The slider is disappeared.
Oh, wait! I've set the volume to "fixed". Changed it to "logarithmic" an now it plays music!

Thank you so much!

Btw: I've installed librespot manually on another board (raspi 1B) on pure raspian and it worked for years now. Never had the problems many users seem to have here.

Best regards,
