Microphones on Compaq F750US not Working

[AlanB66]

I have Ubuntu 8.04 on a Compaq F750US.
'lspci | grep -i audio' reports a Nvidia MCP67 REVa1 device.

The Gnome Sound Recorder 2.22.0 does not record via the internal nor external microphones.

I can provide any information you need, just ask.
I can try things and restore my partition if it doesn't work or screws things up.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu.
    > Ubuntu 8.04
    > 'uname -r' reports: 2.6.24-16-generic
    > 'lspci | grep -i audio' reports: Nvidia Corporation MCP67 High Definition Audio (rev a1)

2) The version of the package you are using, via 'apt-cache policy packagename' or by checking in Synaptic.
    > Assuming "Alsa" here, Synaptic Package Mgr reports:
       * alsa-base 1.0.16-0ubuntu4
       * alsa-utils 1.0.15-3ubuntu2
       * gstreamer0.10-alsa 0.10.18-3

3) What you expected to happen
    > I was hoping my test sound would be recorded.

4) What happened instead
    > Nada. No sound played back whatsoever. And, I do have sound playing if I play a movie or sound file.

2008-07-24: Is anyone looking into this?

Same issue.

Ubuntuforums has all of the information that I gathered about it, including possibly a problem with the Alsa driver not correctly recognizing the hardware in the first place.

Can you confirm this issue exists with the most recent Jaunty Jackalope 9.04 release - http://www.ubuntu.com/news/ubuntu-9.04-desktop . If the issue remains in Jaunty, please test the latest upstream kernel build - https://wiki.ubuntu.com/KernelMainlineBuilds . Let us know your results. Thanks.

I just tested this using a 9.04 Live CD on my Compaq F750US.

The issue still exists when trying to get the internal mic to record any sound; still nothing.
The issue is gone when I use a microphone plugged into the Mic jack on the front of the system, though.

Here's from a Lenovo x200 Tablet

No sound is played.

#8 : has only sound with/through earphones... Just tested it.

Generic trick that sometimes helps: start alsamixer and go to the recording
mixers. There choose the microphone and either 'q'/'z'('y' on German keyboards)
or 'e'/'c' to modify the left or right channel only. Some hw seems to provide
inverse data on left and right, so having them on the same level completely
cancels out the signal.

Hi AlanB66,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 225926

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
