had sound skipping here too with likely the same southbridge:
(AMD64 K8T800 mobo)
# lspci -n
00:00.0 0600: 1106:0282
00:00.1 0600: 1106:1282
00:00.2 0600: 1106:2282
00:00.3 0600: 1106:3282
00:00.4 0600: 1106:4282
00:00.7 0600: 1106:7282
00:01.0 0604: 1106:b188
00:0b.0 0200: 10ec:8169 (rev 10)
00:0f.0 0101: 1106:0571 (rev 06)
00:10.0 0c03: 1106:3038 (rev 81)
00:10.1 0c03: 1106:3038 (rev 81)
00:10.2 0c03: 1106:3038 (rev 81)
00:10.3 0c03: 1106:3038 (rev 81)
00:10.4 0c03: 1106:3104 (rev 86)
00:11.0 0601: 1106:3227
00:11.5 0401: 1106:3059 (rev 60)
00:18.0 0600: 1022:1100
00:18.1 0600: 1022:1101
00:18.2 0600: 1022:1102
00:18.3 0600: 1022:1103
01:00.0 0300: 10de:0185 (rev c1)

backing out above patches didn't help.
Enabling variable samplerate support by loading
snd-via82xx like this:
# rmmod snd-via82xx
# modprobe snd-via82xx dxs_support=5
made the difference here.

Also I completely disabled PCI-quirk-VIA-IRQ-fixup here without
any negative impact.
When active, it reports nonsense here:
"PCI: VIA IRQ fixup for 0000:00:0f.0, from 255 to 0"
"PCI: VIA IRQ fixup for 0000:00:10.0, from 11 to 3"
