Did you have some webcam with microphone in it attached per USB on
the
system? This can also screw up alsa. If so, please remove it, reboot
and give it a try.
Argh, I've got a MIDI keyboard plugged. It's usually stored away but I
connected it the other day when I was doing some music in Windows. I'm
sure that's the cause of the problem (will check tonight after work).
I should have realised when I saw "usb" in the errors.
Many thanks for both replies, Chris.
