I get the same error.
I'm thinking maybe only the midi driver is running, and not the
pcm driver?
/proc/asound/card0 only contains 'id' and 'midi0'. Should it
also contain
'pcm0' or similar?
Again, I use different hardware, so I'm not at all sure, but I have two
directories - pcm0c and pm0p in my /proc/asound/card0 directory. It does
sound like you're missing these.
