I've been having this problem ever since I stared using OSS4. I'm running Arch64 and when I suspend my computer to RAM (using the Sleep button in KDE menu), after resuming I get no sound at all and a lot of errors in dmesg. The sound chip is HD Audio ALC272 in Toshiba Qosmio X300 laptop.

When I try to stop OSS by running "/etc/rc.d/oss4 stop", I get a lot of "SNDCTL_MIX_READ: Input/output error" errors in the console. However, when I start OSS again, it seems to be working. Unfortunately, sometimes OSS just won't unload and the only way out is to reboot.
I compile OSS from the source myself and I believe that I currently have revision 920.
