Hello All, I'm running FC4 with a KDE desktop on a new Pentium 4 dual booting with Windows XP. Under Windows I can play and rip CDs on the DVD drive using Windows Media Player without anything unusual happening. (I mention this only to eliminate the obvious hardware issues.) With FC4 the system recognizes my soundcard: Vendor: Intel Model: Corporation 82801FB/FBM/FR/RW/FRW (ICH6 Family) High Definition Audio Controller Module: snd-hda-intel and plays the usual test tune. The mixer KMix shows all the outputs turned on with 75% volume (except for PCM which doesn't seem to have a mute function.) The CD players xmms and KsCD both appear to be playing from the drive but I can't get any sound. Thanks for the help, Jerry
