Comment 7 for bug 683487

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!!
