[linux-audio-user] My CD Player/Burner stopped working

I have a Sony CD ROM in my Linux box. It has worked fine from the beginning but around the time I recently moved from Fedora Core 1 to Core 3 (Planet CCRMA), it stopped working for burning (using xcdroast) and playing through my Delta 1010LT sound card. The timing could be a coincidence but I suspect the setup got messed up somehow in the transition. If I put a audio CD in it, the sound comes out fine if I plug my headphones into the built-in (to the player) headphone jack but no sound comes through my sound card. My sound card is working fine for other apps like Audacity, Ardour, aplay, etc. Can someone help me figure out what might have gone wrong? Thanks in advance for any tips. Mike Mike Jewell
