I think I'm stumped and would appreciate ideas on where to turn. system-config-soundcard properly finds my Intel soundcard, but the test sound does not play. I have the same symptoms as posted by Gerrit Holl on July 5, but what worked for him isn't working for me. Tried the following, with no joy -- Running system-config-soundcard turning up all volumes in alsamixer blacklisting snd-intel8x0m modem sound driver. rmmod snd-intel8x0 and modprobe snd-intel8x0 (install and remove) I've gone so far as to remove the soundcard entry in /etc/sysconfig/hwconf and removing the entries in /etc/modprobe.conf to try to get the card found again by kudzu and reconfigured. Based on examples I've seen in Google, I think my modprobe.conf was incomplete coming out of the installation. I'm fairly confident that my modprobe.conf is in a bad state, but I have not found a good sample for this card (most of the HOWTOs I've seen give examples for SoundBlaster cards). I'm also not sure how modprobe.conf could go wrong from a clean install. This card works fine under Windows AND worked fine under FC3. For what it's worth, the display in system-config-soundcard is different now than under FC3. Now the Vendor is shown as 'Intel' and the Model is shown as 'Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller' I'd appreciate any ideas on what to try, or even a look at a working modprobe.conf with this card working. Thanks for any help. Erik
