Re: How to unmute the sound?

["Julian Hernandez Gomez" <julianhernandez@gmail.com>]

Hi,

I  had the same problem (this time with an ASUS A8F laptop) but I
managed to fix it by passing the model option to modprobe.  Maybe you
should try again with kernel 2.6.25 (it's now in unstable), I saw that
there is a new model name for your codec chip (STAC9205):

STAC9205/9254
  ref		Reference board
  dell-m42	Dell (unknown)
  dell-m43	Dell Precision
  dell-m44	Dell Inspiron

Just for the record, this is what I did:

Sound always worked fine until one of the last week upgrades to
unstable/experimental, so the first thing was to determine the codec
chip used in my laptop:

$ tail -n 2 /proc/asound/oss/sndstat
Mixers:
0: Analog Devices AD1986A

Then I checked the the ALSA-Configuration.txt for the possible model
names for the AD1986A codec chip and after a few  cycles of:

modprobe -r snd-hda-intel
modprobe snd-hda-intel model=...
alsamixer
speaker-test -t wav -D plug:front -c2 -l2

I found that the right model name was laptop-eapd, so finally  I added
the following line to the /etc/modprobe.d/alsa-base:

options snd-hda-intel model=laptop-eapd
