Let's try doing the following: 1. Add `options EMU_MTX_DEBUG' to your kernconf. 2. Add set the sysctl: dev.emu10kx.0.debug=3D1 . Let's see if anything changes... Also, if you could provide some more hardware stats (say dmesg.boot and/or devinfo -v) and version stats (I already know that you're running amd64 from your kernel config) for the OS that would be helpful as well. I'm going to try upgrading my kernel and I'll try these steps as well. The locking between this driver and some other sound drivers isn't exactly the same (interestingly enough this driver uses Giant locking for some bits, while the ich one doesn't), and there were some past bugs with other branches of *BSD's drivers related to pci bus commands, etc; the other BSDs have dramatically different soundsystems -- I assume the old school soundsystem, s.t. the issues are probably not the same. Thanks, -Garrett
