Hello all,

Im on kubuntu 20.04 and I have no longer surround sound 5+1. When I 
choose the 5+1 Profil in pavucontrol the card is away and I get the 
message: "no output device". I tried also alsamixer with no luck. Only 
analog stereo is working.

I tried

sudo mv /var/lib/alsa/asound.state /root/
sudo mount -t tmpfs none /var/lib/alsa

and did a reboot. Same behavior.

I tried also older kernel with no luck

Can someone help?
