This may happen when there isn't a PCM device on sound card 0 (in your
case, the USB device). Please check whether /proc/asound/devices lists any
PCM devices.

Do you want to use snd-usb-audio or snd-powermac?

If you want to use both, use the following:

        alias snd-card-0 snd-powermac
        alias snd-card-1 snd-usb-audio
        options snd-powermac index=0 ...
        options snd-usb-audio index=1 ...

If the USB device should be sound card 0 instead, exchange 0 and 1.
