Medion + intel hda tests

Medion + intel hda tests

[fab]

Hi,
since I reported bugs as well as I can and gave no answers, I started to
do some very basic tests and sourcecode reading.
I tried to modprobe snd-hda-intel with different "model" option and then
tested all the outputs, I only marked the working ones :

Availables inputs:
 [front] [surround] [center] , [headphone]
tested model :
 3stack        : front
 3stack-digout : front
 5stack        : front
 5stack-digout : front
 w810          : front surround

Ok, as you can see, the w810 is the only offering 2 outputs.
When I say "it works" I mean "we can ear something of extremely low
level and bad quality", no output with no model give satisfying sound.

I haven't tested the SPDIF output since I don't have the appropriate
hardware.

Under winXP, I can have front and headphone pluged at same time with
sound on both. I can swap surround and center outputs and chose between
2 , 4 or 6 channels.

I hope this helps.
As I already said, I'm ready to code and do whatever needed to make this
card working. I just have no knowledge under winXP and very little
driver one.

Best regards.
Fabien Devaux.

Since I've been in vacation and had no net access ;)

This implies that the pin assignment is different from what the normal
models suppose.

I added the "test" model for debugging such cases to ALSA CVS.
Try ALSA CVS version (driver and lib), and set "model=test" module
option to snd-hda-intel module.  Then you'll have fully controllable
volumes and switches.

The noisy output may be fixed by setting "position_fix=1" or
"position_fix=2" module option.

Anyway, please show the content of /proc/asound/card0/codec#* file.
