[Bug 683487] Re: Inbuilt microphone not working on Thinkpad Edge 13 0196CTO

[William DeMeo]

Ben, Thanks for kindly suggesting these solutions.  Unfortunately, none
of them worked for me.  However, just when I was about to give up, I
took a shot in the dark and tried the following:

options snd-hda-intel model=thinkpad

I had nothing to base this on.  I searched for a list of possible snd-
hda-intel model options, but could not find it.  So, I just took a wild
guess and was almost certain it wouldn't work.  Amazingly, it works!

The mic works, the speakers work and, when I plug headphones into the
audio jack, the headphones work AND they mute the internal speakers.
Finally, audio recording also works (which resolves the problem you were
having, Ben, so you might want to try the model=thinkpad option).

-William

[Bug 683487] Re: Inbuilt microphone not working on Thinkpad Edge 13 0196CTO

Hi! My new Thinkpad Edge 13 just arrived yesterday, so of course I
installed ubuntu immediately (version 11.04).  I'm happy to report that
almost everything seems to be working great! ..even the webcam!
However, I'm having the same problem with the internal microphone as
Benjamin.  I tried his solutions with these results:

First, I installed the Crack of the day drivers as per
https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules

Then I tried adding the following to /etc/modprobe.d/alsa-base.conf

options snd-hda-intel model=laptop

I rebooted (since I've forgotten how to use the modprobe, lsmod, etc
commands to reload modules!  ..sadly(?) it has been many years since
I've had to do this sort of thing.)

The result was that I could use the internal mic, however, the headphone
jack was disabled.  Even when headphones are plugged into the jack, the
sound still comes out the internal laptop speakers.  (I think this was
also Ben's experience.)  So, I tried Ben's second solution:

2. Append
  options snd-hda-intel model=ideapad
in the file
  /etc/modprobe.d/alsa-base.conf

The result is that I'm back to where I started: sound comes out the
internal speakers, or the headphones when they are plugged into the
jack, but the internal microphone is disabled.

I'm not sure why this worked for Benjamin and not me.  I tried comparing
our respective outputs from alsa-info, but I'm afraid I don't really
know what to look for.  Well, if someone could suggest something
(anything), I'd be very grateful.

(I'll attach the output of the alsa-info command run on my machine, in
case it helps.)

Thank you!!
