I Have FC4 (kernel 2.6.11-1.1369_FC4) installed in a DELL Inspiron 600m. The sound card is Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97. It was detected correctly and the module snd-intel8x0 was installed during the installation and later soundcard detection. But when I press the "play test sound" button, no sound can be heard. The speaker is not muted. Any idea what went wrong? Appreciate it. Xiaodong ____________________________________________________ Yahoo! Sports Rekindle the Rivalries.
