install kmix, enable all channels, check capture, set 'input source' to Int Mic I have tried many mixer apps with my 6930 but kmix is the only one that provides the option. Hope this helps.

I've had a similar experience using an Acer Aspire 5810TZ.
There is an excellent post on this that can be found at:
http://ubuntuforums.org/showthread.p...ht=acer+5810tz
Fot the 5810TZ the problem was resolved by installing the linux-backports-modules-alsa-karmic-generic packages. They are easily found in synaptic or apt-get.
I had tried a new installation of alsa, but it did not solve the issue permanently. It seems that between those two fixes, the majority of the intel integrated mic issues can be resolved. Thanks to PatrickVogeli, the power saving tips also brought my battery life much closer to the 8 hours it is advertised as running.
this is something extremely simple and as such easy to overlook but over amplification can result in either little or no audible recording, or in very staticy sounding garbled illegible recording. if you lower the input/capture volume to approximately one eighth to one quarter volume and then work your way up you may find that your problem is fixed. also thank you ideathproof for posting those step by step instructions they are very useful
The following worked for me.
Now the system even switches from internal to external mic depending on whether the latter is plugged.
I use Ubuntu. Anything starting with "K" might conflict with this solution.
My device:
1. Install padevchooserCode:$ sudo lshw -C multimedia *-multimedia description: Audio device product: 82801G (ICH7 Family) High Definition Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 02 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=HDA Intel latency=0 resources: irq:16 memory:56340000-56343fff $
2. Reboot
3. When adjusting the sound levels of the mic, unlock the channels and adjust left to 90% and right to 5%.
Without Step 3 I had it working well except on Skype. Now it always work.

This (ie post #21) is the most hopeful solution I've seen in this thread - but I'm reluctant to install kmix: it looks like it needs me to install the whole basic KDE stuff, and I don't want to do that - I like the standard Ubuntu interface much better (I've got an Aspire 532h w Ubuntu 10.4 installed, and this dead internal mic is STILL going on!
anyway, if I install kmix through Synaptic, and all its dependencies, will the rest of Ubuntu stay the same, or will I find myself in KDE land?
[update] I checked and I already am running alsa v1.0.21, so no point in loading an older version I think. Also, trying to use Ubuntu facilities first, I did a system test and found that the internal mic seemed to work fine! Then I tried it with th sound recording app in the System ->Sound menu, and that too works just fine. It seems that all I really have here is a compatibility problem with Skype, the most important thing I want that mic for. Skype simply does not recognize it at all. And this is Skyp v2.1.0.81, installed via Synaptic.
At least this should be easier to pursue than a general dead microphone.

I don't know if this will work for you but
1. I installed pavucontrol
2. then opened Applications-> Sound & Video-> PulseAudio Volume Control.
3. I then clicked on the "input devices" tab.
4. I unlocked the sliders by clicking on the little lock icon.
5. I moved the right slider all the way to the left (muted) and the left slider I adjusted as needed. Works perfect without tweaking the system.
Thanks, jazzman, it worked exactly as you said, and being able to download a relatively small package like that was very encouraging. I wanted to stay within the Ubuntu way if you know what I mean.
I fussed a bit with the sliders for the mic, wondering if maybe using some of the right side would work out, and in fact the internal stereo mic works fine with both channels up and even - with anything except Skype. Only when I mute the right channel and then adjust the left does Skype work - AND I had to shut off Skype's automatic level setting to keep it working right, or it adjusts the level downward until you can't hear anything. So Skype is the bad actor here, but this work-around is great, thanks again!
love to hear your bass work some time
