I'm running FC5 on two 600X's that exhibit the same problem: No sound after a resume. I know I can rmmod the snd_cs46xx module and modprobe it, but I can't do that (even as root) when I'm logged in an X session because it's in use. lsmod shows that it's being used by one process, but gives no name. As a work-around, I can log out, use a console session and stop and start the module. When I log back in, sound is back. Is there a way to 1) automate the work-around, 2) fix the driver or 3) use some other driver/tool? I'm afraid I might miss responses to the list, so please try to copy me. I'll post any solution to thinkwiki. Thanks, Chris S
