built-in mic not working with snd-hda-intel on Dell Vostro 1710

[Jeremy Jongsma]

My Dell Vostro 1710 has two mic inputs - a normal mic jack and a built-in microphone on the top of the screen. The jack input works, but the built-in does not. Tried with stock configuration and with model=dell module option (using snd-hda-intel driver).

In the Gnome volume control "Options" tab, a "Front Mic" source is displayed in the Input Source dropdown, but selecting it has no effect.

Hi Jeremy,

I think this may just be an issue with your mixer settings. I myself have a Dell Inspiron 1420 and although my soundcard is one revision older than yours (and I'm also unsure of which codec you use), my built in mic is working here.

I've attached a screenshot of the settings I'm using here. I'll also attach the output of my alsa-info.txt file which can be generated by downloading and running http://alsa-project.org/alsa-info.sh with the --no-upload option:

./alsa-info.sh --no-upload

Additionally, I've attached a sample recording to prove I'm able to record with the built-in mic. If you are still having trouble with the built in mic, it would be good for you at attach your alsa-info.txt file. Thanks.

[Jeremy Jongsma (jeremy-jongsma)]

Thanks Leann. My mixer settings are attached in the screen shot. I will attach ALSA settings below. The sound recorder in my screenshot results in a blank file - the mic level reading is just from having the recording levels cranked so high in the mixer during this test.

Also, I should mention that this mic works fine in Vista, so I've eliminated hardware issues as the problem.

[Jeremy Jongsma (jeremy-jongsma)]

Also, in the "Options" tab, my Input Source options are: Mic, Front Mic, Line, CD. Selecting Front Mic (or any other) makes no difference.

Hi Jeremy,

I recall that it was important that I have the "Digital Input Source" set to "Digital Mic 1". I didn't see this in your mixer settings under the "Options" tab. In order to display it, click "Preferences" and tick the "Digital Input Source" option.

[Jeremy Jongsma (jeremy-jongsma)]

No "Digital Input Source" exists - screenshot of available tracks attached. I tried "Capture 1" also - no luck.

i have a dell vostro 1710 and have similar problems under both intrepid and jaunty.
my built in mic will not record anything but noise despite trying all the combinations
of model flags (dell,3stack,laptop-eapd) and module load and mixer options.

The main problem here is that people are assuming that all dell vostro's use
the same chipset and they dont , it changes with the model numbers (see gentoo wiki)

This is also getting tangled up in other confusions because the snd-hda-intel driver is used
by many different soundcards all with different codecs and different i/o layouts so this will
almost certainly not be relevant to other models.

mine uses a Realtek ALC268 , as verified by the output of

cat /proc/asound/Intel/codec#0
(see attachment for output)

I'm a pretty experienced linux user and am happy to help provide more info
and or test if needed , i would love to have this working for me and for others.

The built-in mic is now working well on my Dell Vostro 1710 using Karmic. The module is loaded with the following option :

options snd-hda-intel model=dell-m23

[Jeremy Jongsma (jeremy-jongsma)]

This is now working properly on my Vostro 1710 with a fresh install of 9.10.
