Bug#532613: Possible cause?
I tried this workaround with poor results. If I crank the first of
those four mixer levels all the way up and turn the volume of my
speakers all the way up, I can hear something. But it's nowhere near
reasonable. The other three levels have no effect.
I have a VIA MII10000 with this sound chip:
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 50)
I also did a diff of kernel messages between 2.6.26 and 2.6.30. Here is
the relevant section:
+VIA 82xx Audio 0000:00:11.5: PCI INT C -> Link[LNKC] -> GSI 5 (level, low) -> IRQ 5
VIA 82xx Audio 0000:00:11.5: VIA VLink IRQ fixup, from 9 to 5
-PCI: Setting latency timer of device 0000:02:00.0 to 64
+VIA 82xx Audio 0000:00:11.5: setting latency timer to 64
