[gutsy] microphone doesn't work after kernel and kernel-modules update

Similiar problems on Lenovo 3000 N100. The card behaves as if the "external amplifier" switch is permanently on (normally this causes the laptop to disable external speakers but causes distortion), but the switch itself disappears from mixer along with several other options.

Generally a second iteration of regression (last time I checked, several months ago, the Feisty drivers worked ok, with headphones auto-detection and without distortion. The gutsy kernel regressed to the state describe in bugs #88546 and #92719, and now regressed further.

Confirming: 2.6.22-10 is broken. Seems like the model parameter to snd_hda_intel do not take effect anymore.
On my Toshiba Satellite P205 with 2.6.22-9, model="lenovo" the sound (mic, speakers muting etc.) worked 100% OK. Now I've got half the options in the alsa mixer and they don't work as expected.

Strange. It doesn't work on 2.6.22-9 on my machine (HP Pavilion dv9000 notebook with hda-intel). Back when I used Feisty it worked fine.

I have the same problem on my HP Compaq nx7400. It seems like there's some sort of internal feedback going on (like the input is replicated on the output and back to the input)

same problem here. i am using HDA Intel chipset an microphone isn working anymore.

Using Gutsy Tribe-5 64-bit I appeared to be suffering this problem, but found an explanation and solution.

1. Open Volume Control
2. Edit > Preferences: select all tracks (including Digital so you can keep an eye on things)
3. On the Switches tab, select Microphone
4. On the Capture tab, ensure the Capture track is enabled and the sliders are up

Keep Volume Control open and visible

5. Start Sound Recorder
6. Choose 'Record from input' "Capture"

Note that the Microphone symbol in Volume Control>Capture tab gets disabled

7. Re-enable the microphone in Volume Control > Capture
8. Start recording

Note that the 'Recording from input' source changes to "Digital" and the microphone symbol in Volume Control>Capture tab gets disabled again.

9. Whilst still recording, re-enable the microphone in Volume Control > Capture
10. Stop recording
11. Playback (you should hear the recorded sound)

It looks like some kind of strange interaction with Sound Recorder and/or Gnome because if I use Audacity, and select "ALSA: HDA ...." as the input source there is no problem with the input switching.

With Gutsy 64-bit Tribe-5 + updates of 10th September 2007 this no longer appears to be a problem.

According to TJ it appears that this bug has been resolved. Changing the status to 'Fix Released'. Please feel free to re-open this bug if it is still an issue. Thanks!

I am facing the same problem also. Thanks to helpful message from TJ (wrote on 2007-09-03), the microphone is works now. It is due to configuration problem in Volume Control
