After installing the November update, librespot gives this error on playback:

Is there an option I can set to fix this or should I downgrade?
Just a guess:
mv .asoundrc .asound.backup
and do a reboot and try
I don’t have an .asoundrc in the osmc homedirectory. Normally librespot is started with the raspotify systemd unit (doesn’t work currently either), that looks like this:

# To make your device visible on Spotify Connect across the Internet add your

Any other ideas? Can this be related to the November update? Any changes in how sound devices are handled? It looks like librespot can’t find a suitable device, implying that it’s in use? I tried stopping the mediacenter service but that made no difference.
osmc@osmc0:~$ librespot --device ?

It looks like the matter is in hand over there.
