| ** WARNING **: oss_open(): Failed to open audio device (/dev/dsp): Device busy

| Can anybody suggest a quick fix? I won't mind entering a few commands to restart snd device...

| More information on my system:
| I configured soundcard my putting "device pcm" in my Kernel.conf
| My soundcard is CS46xx
| Yes, I disabled "PCI bus sleep mode" from BIOS
Try this patch in /sys/dev/sound/pci then rebuild your kernel and reboot.
I'm sure it is not the best way for me but it works for me and is
better then doing a kldunload/kldload.
