Title:
STAC9228 / Dell XPS M1530 / Mic needs a boost, very low signal
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
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.
