ah...yes :)

Thanks.  I should have thought to look in my MB docs.

Well, kmix did it for me.  I now have sound in KDE and on the command line.

The chipset numbering is a mystery to me still, though - the MB docs say 
VT8235 south bridge.  But, here is lspci (for real):

00:00.0 Host bridge: VIA Technologies, Inc. VT8374 P4X400 Host Controller/AGP 
Bridge (rev 03)
00:01.0 PCI bridge: VIA Technologies, Inc. VT8235 PCI Bridge
00:10.0 USB Controller: VIA Technologies, Inc. USB (rev 80)
00:10.1 USB Controller: VIA Technologies, Inc. USB (rev 80)
00:10.2 USB Controller: VIA Technologies, Inc. USB (rev 80)
00:10.3 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 82)
00:11.0 ISA bridge: VIA Technologies, Inc. VT8235 ISA Bridge
00:11.1 IDE interface: VIA Technologies, Inc. VT82C586/B/686A/B PIPC Bus 
Master IDE (rev 06)
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio 
Controller (rev 50)
00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 74)
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY 
[Radeon 7000/VE]

So, it seems to me that linux thinks the sound chip is a VT8233.  I'm 
satisfied now that sound works, but I'll do any more probing you want if you 
are still curious.

Thanks so much,
Josh
