[Solved] Sony vaio internal mic

Hi all, I've a big problem with the internal mic on my sony vaio VGN-FE. It simply doesn't work, and all i can register (if I set all volume control sliders to 100%) is a little noise, without traces of real sounds I make.

Alsamixer

(there isn't a "mic" slider, quite strange, i think)

Gnome volume controls

gnome-alsamixer

The sound chip is a SigmaTel CXD9872RD/K over an hda-intel

# lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

# lsmod | grep snd
snd_seq_dummy           2696  0

soundcore               6784  1 snd
snd_page_alloc          8812  2 snd_hda_intel,snd_pcm

I already tried to put

options snd-hda-intel enable=1 model=vaio position_fix=0

in /etc/modprobe.d/modprobe.conf

but it doesn't change a bit.

Any idea?

Thanks

Re: [Solved] Sony vaio internal mic

I have Sony Vaio VGN-FZ38M
my modprobe.conf:

options snd-hda-intel model=vaio

and

lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

Try in gnome-volume-control in preferences mark all options, after in options tab change input source (i have front mic)
and in gstreamer-properties change input.
And play with sliders.
It worked for me (the option to choose input source in sound recorder disappeared, but it works), I had to made a lots of attempts with changing different possibilities to find it out.

here's how it looks:

good luck

Re: [Solved] Sony vaio internal mic

Unfortunately i don't have the "options" tab in gnome volume control.
I selected the right input in gstreamer-properties (and lost the input choice in sound register), but nothing changed

Re: [Solved] Sony vaio internal mic

I didn't have this options, but i could enable it in gnome-volume-control preferences. After it appeared  as a tab.

edit:
ok and there is another thing i had to pump up "strengthening of input" (or something like this - google translate)

Re: [Solved] Sony vaio internal mic

Dont't give up

maybe try to put in your modprobe.conf just:

options snd-hda-intel model=vaio

-reboot,
-check all options and max all sliders in gnome-volume-control,
-check if you can choose another (reading from your screenshot) "dispositivo" (I have OSS mixer where I found "strengthening of input")
-max all sliders there as well,
-then try to record changing input source (gstreamer-properties and any options in gnome-volume-control).

Some time ago I had the same problem and intensive google searching didn't help, I succeed after playing a lot with this ^ settings.
I've just check that crucial setting for me is this "strengthening of input", strangely this is in playing not recording tab in OSS mixer.

There is a finite amount of combination, so just try them all

Re: [Solved] Sony vaio internal mic

With the latest kernel update, the "option" tab in volume control showed up, and now my mic works!
Thank you very much folletto
