Internal Mic not working

NorthernLights · 2012-06-01 13:57:25

Hey Guys,

I have been trying to get my internal mic working on my laptop for ages now without any success any advice would be greatly appreciated. I have followed the alsa configuration on the arch wiki. I have also looked at the wiki for my laptop https://wiki.archlinux.org/index.php/To … _X505-Q830

The error I get at the pre boot screen says the following
Found hardware "HDA-Intel" "Conexant CX20583 (Pebble HSF)" "HDA:14f15067, 1179ffd5, 00100301" "0x1179" "0xff50"
/usr/sbin/alsactl: setcontrol:1328: failed to obtain info for control #2 (no such file or directory)
/usr/sbin/alsactl: setcontrol:1328: failed to obtain info for control #3 (no such file or directory)

The output of alsa-info script can be found here: http://pastebin.com/XngB9twv

Cheers

Are you using arecord to test?

Is it unmuted if you go into alsamixer and press F4?

Also make sure it's set to capture: in the F4 (Capture) section of alsamixer, move to the Capture slider and hit space. Should show CAPTURE beneath the slider.

Yes. Make sure it's set to capture. Are you using pulseaudio? If so:

# pacman -S pavucontrol
$ pavucontrol

You then click on the "Input Devices" tab of pavucontrol, make sure it looks similar to this:

BTW, I don't use ubuntu. Just light-themes.
Make sure that it is unmuted there, then see if the slider indicating volume level moves. If it does, you're in luck!

Ok, will not do it again. Sorry about that.

hmmm... just to further add to the confusion factor...

I went through your alsa-info data... and good job including it in your initial post.

!!Modprobe options (Sound related)
!!--------------------------------
snd_hda_intel: model=dell-vostro

Try changing that ALSA model "quirk" from dell-vostro to hp-laptop.

Next, like Pres is alluding to, use arecord for testing. In your case, use something like this on a command line:

arecord -f cd -vv -V stereo -D plughw:0,0 /dev/null

Even though you're using PulseAudio, that should work with no changes to your ALSA config file. So use it to try recording some sound while looking for a "bouncing" text VU meter. Even though I don't see anything obviously wrong with your current alsamixer setting, try changing some of those controls in another terminal if it doesn't seem to work... while keeping one eye on the arecord VU meters.

And lastly...

The error I get at the pre boot screen says the following
Found hardware "HDA-Intel" "Conexant CX20583 (Pebble HSF)" "HDA:14f15067, 1179ffd5, 00100301" "0x1179" "0xff50"
/usr/sbin/alsactl: setcontrol:1328: failed to obtain info for control #2 (no such file or directory)
/usr/sbin/alsactl: setcontrol:1328: failed to obtain info for control #3 (no such file or directory)

Every once in awhile, the ALSA developers will change the "wiring" involved with Intel HDA chips. So after a system update, the ALSA settings normally saved during a shutdown of your box may become "stale" and therefore start complaining when it tries to read it back during a boot.

There's an easy fix... just fire up alsamixer and verify that the setting are still what you want, then enter this on the command line (with root authority):

alsactl -f /var/lib/alsa/asound.state store

This will overwrite the file with new ALSA settings.
