All, I am running RH 7.3 on a 600e and am unable to get sound to work reliably. Sound works under Win98 so the H/W and BIOS are probably ok. Attempts to run sound applications seem to start ok but end with a device unavailable or busy message. I have also tried independently to install ALSA 0.9 rc3. Has anyone had success with .9? Is there a step by step howto? Thanks Dan
