>Description:
The ALC850 sound chipset has more than 2 channels output (4 of 6).
But only 2 works.
Following Ariff's advices, I put the required information :
1) uname -a
FreeBSD marsu 6.1-RELEASE FreeBSD 6.1-RELEASE #0: Thu Dec 21 10:16:41 CET 2006 root@marsu:/usr/src/sys/i386/compile/FREEBSD_61 i386
2) pciconf -lv | grep -B 4 audio
pcm0@pci0:19:0: class=0x040100 card=0x812a1043 chip=0x003a10de rev=0xa1 hdr=0x00
vendor = 'NVIDIA Corporation'
device = 'MCP04 AC'97 Audio Controller'
class = multimedia
subclass = audio
3) dmesg | grep ^pcm
