Comment 6 for bug 71704

You said that you had 2 cards and this shows 2 cards (the hw:0 and hw:1). Try the following command

arecord -l

which should display what alsa thinks the capture devices are and

aplay -l

for playback devices. I don't really know what's happening here. This shows the delta as card 0 and on your first report it was card 1. The other card in the last list you gave might still be the SB but we're reading the wrong description. arecord seems to give longer info.
