I have never gotten sound on a 600X running Linux to work after a suspend and resume cycle. I think there is a bug in the snd_cs46xx module, but I cannot confirm that, and wouldn't know where to report it anyway. A new driver would be an ideal solution. I'm a long-time Red Hat user, so I've been using Fedora Linux on the 600X's that I take care of, and CentOS 5 starting today. I've found one page that says you can put the line "MODULES=snd_cs46xx" in the file /etc/default/acpi-support if you're using Ubuntu, but of course that file doesn't exist in Fedora/RHEL/CentOS. Is there a way I can force the removal of that module (rmmod snd_cs46xx) on suspend and restarting of it (modprobe snd_cs46xx) upon resume? It's not even easy to do manually because the Gnome desktop holds the device open all the time. To get it to work now after a resume, I have to log out, switch to a text console, remove and re-start the module, switch back to the GUI and log in. Sound works fine after that until another suspend/resume. What's the right way to fix this? Find the driver maintainer? Many thanks, Chris Schumann
