Bug#428270: libopenal0a: sound is badly distorted on intel audio using alsa

I guess so, although I'm absolutely no kernel expert. Maybe a bad
default driver, dunno.

It might have to do with some options missing, but if only openal-based
applications have this problem...

In the kernel sources, check sound/pci/hda/, the mapping is apparently
(at least in my case) this way:

$ grep MCP51 -r .
./hda_intel.c:  { 0x10de, 0x026c, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_NVIDIA }, /* NVIDIA MCP51 */

$ grep 0x10de -r .
./patch_analog.c:    SND_PCI_QUIRK(0x10de, 0xcb84, "ASUS A8N-VM", AD1986A_3STACK),

And this mapping wasn't present in 2.6.18. If such a mapping exists for
your card, I guess that your problem has nothing to do with a bad driver
mapping, at most with a missing option.

Cheers,
