STAC9228 / Dell XPS M1530 / Mic needs a boost, very low signal

[Kokos]

Hi,

I cannot force Ubuntu to work with the integrated sound-card in my laptop it's Dell XPS M1530 and sound card is STAC9228.

Actually it captures sound from mic but its volume is very low, it's too quiet and needs boost. I already tried few combinations with:

gnome-alsamixer
alsamixer
pavucontrol
and of course I tried following ALSA MODELS:

STAC9227/9228/9229/927x
=======================
  ref Reference board
  ref-no-jd Reference board without HP/Mic jack detection
  3stack D965 3stack
  5stack D965 5stack + SPDIF
  5stack-no-fp D965 5stack without front panel
  dell-3stack Dell Dimension E520
  dell-bios Fixes with Dell BIOS setup
  volknob Fixes with volume-knob widget 0x24
  auto BIOS setup (default)

Unfortunately it's still very quiet.

I also read on forums (2008ish) that people already had issues with this configuration but they were able to handle it switching input device to "digital mic", but I don't have such an option in modern Ubuntu..

Here is my alsa-info result: http://www.alsa-project.org/db/?f=7af515217ca211337c5c364231b7480eb5575bcb

Please advice things I could check. Thank you.

Hi Raymond, thank you for your reply.

I just tried different models and stayed with dell-BIOS as it was the last one I've tried - no visible difference to me. Shall I use rather different model or remove that option at all?

Regarding alsa driver, what would be the best source for the driver? Shall I use oem-audio-hda-daily-dkms package from ppa:ubuntu-audio-dev/alsa-daily?

Thank you a lot for confirmation.

Kind regards,
Konrad

try

hda-jack-sense-test -a

to find out mic Jack support detection or not

if yes, you need to clear misc bit of mic pin default (bit 8)

0x0e 0x02a79030

instead of

0x0e 0x02a79130

[Raymond (superquad-vortex2)]

try hda-jack-retask to clear misc bit of node 0

you need to fix mic jack node 0x0e similar to above patch if you Mic Jack support detect
