Hello,
I'm trying to get the sound (snd_hda) working on my Macbook pro model
3,1.
I run FreeBSD 7.1 but snd_hda is taken from current of today.
Identification:
$ pciconf -vl
hdac0@pci0:0:27:0: class=0x040300 card=0x00a0106b chip=0x284b8086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82801H &SUBSYS_81EC1043&REV_02\3&11583659&0&D8'
class = multimedia
subclass = HDA
[Warning: according to the alsa project the PCI ID is shared between
some Mac with differents HDA configurations:
http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=93a1a5eb70be5cc14990b97ef2460212e32658dc
and

]
I must use a gpio0 quirk to get the speaker sound so i added a device
hint:
hint.hdac.0.config="gpio0"
And I should fix the association between the headphone pin and the
speaker.
device hint:
hint.hdac.0.cad0.nid21.config="as=4 seq=15"

1 color
Now when i plug a headphone, the sound from the speaker is
muted but i don't hear sound in the headphone. There is some sound but
the level is very very very low.
I think i have to add a ovref quirk somewhere or another quirk, but a
quirk
hint.hdac.0.config="gpio0 ovref" does not seem to do anything:
hdac0: FG config/quirks: gpio0 forcestereo ivref50 ivref80 ivref100
ivref
Why ovref is not listed? How to add a quirk 'ovref' or 'eapdinv',
there is no example in the man page?
files:
- hda and pcm output:

The sound works fine under Linux, for information I add:
- hda codec output from Linux(ubuntu-8/10)
(ie /proc/asound/card*/codec*)
http://user.lamaiziere.net/patrick/keep/hda-linux.txt
- codecgraph output:

(is it useful for you?)
Any help will be very welcome, thanks.
Regards.
