Turns out my change to pipewire has failed. Bascially pavucontrol does not connect to server and so you have no sound live. There is a workaround if only a little long winded. Set your local mirrors via abserver, update and install pulseaudio package then run pulseaudio –start. This should allow pavucontrol and sound to work.
I will of course fix this in future releases. Forgive me as I have used alsa for many years but all the big distros seem to be using pipewire.
Normal service will resume shortly..
Stay safe 😉
