Thinkpad Edge 11" (AMD) [Conexant CX20582]: Internal Mic. & Heaphone Jack not working

[Benjamin Schmid]

Hi there!

I have a similar problem as Bug #682565 and Bug #683487 but with the AMD Nile platform of the Lenovo Thinkpad Edge 11" Laptop on Ubuntu 10.10:
- The internal Microphone doesn't seem to work at all
- The headphone jack is dysfunctional

These are the things I tried:
1. ALSA Tweaks: olpc-xo-1_5 / laptop / ideapad / lenovo-101e
2. Fiddling with ALSA-Mixer Input options on each tweak
3. Installed up-to-date drivers per https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules.
4. Using Kernel 2.6.35-24 vs. 2.6.35-23 from maverick-proposed

Until now I completely failed: Neither did I get the combo headphone port working nor was I able to recording any noise from the internal mic.

Please let me know if I can help tracking this problem further down. I also attached the alsa info ouput for your reference.

Many thanks!
- Benjamin

Appending
  options snd-hda-intel model=ideapad
in the file
  /etc/modprobe.d/alsa-base.conf
solved both problems for me : Audio Jack and internal mic. working with Skype.

Only the audio recorder seems to ignore the internal mic,. ?!

Hi Benjamin and thanks for your bug report. It seems like many Lenovos need the "ideapad" model quirk.
