Actually, you have two sound cards: card 0 (2-in-1 Phone) and card 1
(Intel ICH5 Modem).  If you didn't have any sound cards then you'd see
the error I'm getting.  Is a "2-in-1 Phone" device actually a device to
play audio?  If so, then run the Soundcard Detection applet (menu System
-> Administration -> Soundcard detection), select your device, and click
the "Play" button (click "repeat" to keep it playing).  If you hear the
guitar playing then your problem is just a device permissions issue.
