possible snd_hda_intel jack-sensing issue with device 8086:1c20

possible snd_hda_intel jack-sensing issue with device 8086:1c20

[Chris Pemberton]

CentOS 7 x86_64
Asus P8Z68-V motherboard
Realtek ALC892
Gnome 3 desktop
nVidia GTX 770 with nVidia's driver

With BIOS set to HD for both rear and front jacks, I experience the problems I reported here:

https://bugs.freedesktop.org/show_bug.cgi?id=86158

Basically, sound works, but the selected output keeps auto-magically flipping from Analog-Out to Headphones and back so fast you barely hear a click..

Tried all sorts of snd_hda_intel module options and it didn't change.

Finally changed BIOS to set front jacks to AC97 (left rear jacks as HD) and sound works great... but no jack sensing occurs at all...

I can live without the jack sensing... but if anyone wants a stab at a fix, I'm game.

I've got the HDA Analyzer downloaded and running if that helps.

My device has id 8086:1c20

Perhaps similar to this bug that was brought to my attention?

Thanks.

Could you check the pin connection again?  The symptom appears more like
a hardware problem.

I opened up the machine and re-seated the connector to the motherboard.  
The problem persists.

The motherboard has two adjacent ports for front panel audio; one marked 
"HD" and the second "AC97".  The single cable from the front audio jacks 
has two connectors at the end; one marked "HD" and the other "AC97".

If I connect the cable end marked "AC97" to the port marked "AC97" and 
set the BIOS for "AC97 front panel", should I expect everything to 
work?  I'd have HD audio at the rear ports and AC97 at the front?  That 
would be fine as I only expect to be using headphones at the front from 
time to time.

Thanks

I looked again and the motherboard only has ONE front panel audio socket 
and the case cable has two ends - one labelled HD and the other AC97.

Hooking up the cable end labelled AC97 and setting the BIOS to AC97 
seems to be working.
