system info

Hello, I'd like to submit a bug, which happens with me from 9-stable, as I remember. Bug occurs on Creative SB0880 X-Fi device.

# pciconf -lv -a hdac2
hdac2@pci0:6:0:0:       class=0x040300 card=0x00421102 chip=0x000b1102 rev=0x04 hdr=0x00
    vendor     = 'Creative Labs'
    device     = 'X-Fi Titanium series [EMU20k2]'
    class      = multimedia
    subclass   = HDA

The system information is in attachment.

The problem happens when I switch dev.pcm.7.play.vchanformat: s16le:2.0 to s16le:5.1. After this switching system freezes if I run any sound in any application. Only reset button helps. Also, must say, internal sound card on motherboard works fine with play.vchanformat:s16le:5.1.

Is this bug reproducible with the most recent FreeBSD versions?
