Hi all,

I'm working on my laptop to better use mic, headphone and speaker
(internal and external).

The laptop is a Vaio VGN-FW11E and the sound card is

With a standard Fedora 9 installation (updated) I can use the speaker
and an external mic.
I can use also the camera but not the internal mic (that I think is
present near the camera).
Alsamixer and kmix do not show options for mic other that "Front mic".
When I insert headphone, the speaker continue to sound (and also the
headphone).

I tried to use other models for hda-intel driver using the options files
in /etc/modprobe.d
whith  options snd-hda-intel model=hippo
headphone inserting mute the speaker, but mic do not work
kmix shows  mic - front mic - line - CD as input source but noone works without an
external mic

with
 options snd-hda-intel model=sony-assamd
is the same but with less options as input and output.

Someone can help my to found the right model?

Alsa modules installed are
 alsa-lib-1.0.17-2.fc9.i386.rpm
 alsa-utils-1.0.17-2.fc9.i386.rpm

Have you removed PulseAudio? No, not disabled... Warning, some other things may stop working, but if what you need works it may be a lesser evil. FC10 could be made to work with PA if you wasted^H^H^H^H^H^Hspent enough time onthe config, and FC11 has taken away the sliders. I have been unable to get sound working at all on FC11, I just have put that on my personal blocker list for installing FC11 on a machine which needs sound.


This has nothing to do with pulseaudio. The internal mic  is generally a digital mic.
Using "alsamixer -c 0" should show an option to select the digital or the analog (external)  mic. However, this depends on the alsa driver being used. The current
stable version is 1.0.20, but Fedora is always behind.

I can select the digital mic on my Dell Vostro laptop, but the sound is too low
to be useful, and I prefer to use the external anlog mic, than spenting days on the
alsa development list because of that.
