[FIX] 2.6.16.17 + mobo w. VIA chipset = sound probs.
Hi,
I don't know what the Debian maintainers of the latest stable kernel
will do, but if you have a mobo with a VIA cipset *and* use the
2.6.16.17 kernel *then* you will have sound problems.
Apply the 2 patches attached in this order:
1) PCI-VIA-quirk-fixup-additional-PCI-IDs.patch
2) PCI-quirk-VIA-IRQ-fixup-should-only-run-for-VIA-southbridges.patch
and the sound problems will go away.
