[alsa-devel] [BUG - REPORT] ALC892 not working

[Xristos Boul]

Hi everyone,

I'm having a problem with my line-out port not being working properly.
Specifically it can't play audio when the 'alsamixer' auto-mute mode is
enabled, so sound is coming only from the headphones.However, when
auto-mute is disabled the sound is coming from both ports simultaneously.

I'm using the Asus Z170-A mobo with ALC892 codec, OS: Arch

I ran alsa-info.sh on both cases and i saw that the Pin-Complex 0x14 had
'Pin-ctls: OUT' when  auto-mute was disabled whereas when auto-mute was
enabled it was 'Pin-ctls: 0x00' (as it currenly is).

So i ran HDA-analyzer tool and changed that widget setting to 'OUT' and
obviously i produced the same behaviour like when i disabled 'auto-mute'
(again sound coming from both ports) and also in all cases PulseAudio lists
the 'Line-out' port as 'unplugged'.

Also 2 more things:

1st: In BIOS when i changed the driver for the Front panel from 'HD-Audio'
to 'AC97' and the ports worked correctly, however no 'auto-mute' mode was
available so i had to mute the ports manually when i plugged/unplugged the
headphones for e.x

I tried uninstalling PulseAudio to see if it was the case but the problem
persisted so i think it really is some codec problem since i also have a
similar problem in Windows OS.

2nd: When i unplugged the Front-panel connection from the mobo the port
played correctly. So is it maybe a mixer problem or something related?

Finally i tried every 'model' parameter from HD-Audio-Models.txt for ALC892
but got nothing.

In any case i'm attaching the current alsa-info.sh. If you would like i
could also send alsa-info.sh for all those cases above.

I don't think i'm alone in this issue but i would greatly appreciate the
help!

Thanks in advance.
