The good news is that all sound works fine for me (I use kde), and at probe time I see this: > pcm0: port 0xcc00-0xcc03,0xd000-0xd0ff irq 9 at device 4.5 on pci0 The less good news is I'm not sure if this is a soundblaster compatibility shim, what I have in my config file is: > device pcm # For PnP/PCI sound cards > device csa # Crystal Semiconductor CS461x/428x PCI > device sbc # Sound blaster I'm not sure why I have that "csa" in there. I didn't know about /dev/sndstat, but it says: > rt% cat /dev/sndstat > FreeBSD Audio Driver (newpcm) Jan 24 2001 22:01:54 > Installed devices: > pcm0: at io 0xd000 irq 9 (1p/1r channels duplex) > rt% Peter -- Peter Dufault (dufault@hda.com) Realtime development, Machine control, HD Associates, Inc.
