Oh, now ID number decreases to 0xxx? :)
Id 0c0c is readout from "lspci" like below: [amanda@amanda-fedora-16 ~]$ lspci
00:03.0 Audio device: Intel Corporation Device 0c0c (rev 01)
00:1b.0 Audio device: Intel Corporation Device 8c20 (rev 01)
While we are on this: could you verify whether position_fix=4 (combo) options works for Haswell? In this mode, LPIB is used for playback positioning while POS buffer is used for capture.
Seth (Cc'ed) figured out that this mode works better than the default (usually POS buf both for playback and capture) on the recent Intel controller chips, so I guess it'd be applied to Haswell, too.
I'm afraid no better result to provide now. This patch is to fix codec probe error at initialization. you can get details at this bug page: Bug 829405 - [Intel 6.4 Bug] Shark Bay: sound related warnings/errors in dmesg https://bugzilla.redhat.com/show_bug.cgi?id=829405
The other patch about HDMI device id could get correct device list by "aplay -l", but there's still some problem to detect HDMI monitor, so i cannot test audio on Haswell HDA now. But once the HDMI monitor detection works, i will provide the test result of Seth's patch.
I think if someone has Haswell HDA plus normal ALC* codec, it could help much to test the patch easily.
So Takashi you could reject this patch until i send out the updated one with test result then.
thanks --xingchao
thanks,
Takashi
