It would have been nice if this had fixed it. > I have take a look to the history of changes of hda_intel.f and found that : http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0a27fcfaaf61108d94f0377f91bed81b2dd35f52 in the source I'm seeing a blacklist : /* * white/black-list for enable_msi */ static struct snd_pci_quirk msi_black_list[] __devinitdata = { SND_PCI_QUIRK(0x1043, 0x81f2, "ASUS", 0), /* Athlon64 X2 + nvidia */ SND_PCI_QUIRK(0x1043, 0x81f6, "ASUS", 0), /* nvidia */ {} }; And on my eeepc 1201n there is lot's of nvidia things...How can I know if I'm on this blacklist or not ? ...sorry, I don't have a lot of knowledge in C. But this could be explain why msi is not enabled by default...
