Dunno, probably not.

PA tries to open audio device via a lot of different device strings,
but apparently it may not be opened via any of them. Could you check
if you can open the device with aplay? (i.e. "aplay -f CD -D hw:0 <
/dev/urandom" or something similar?)

Maybe you have a permission problem?

Please check with strace what actually happens.
