Hi Claudiu,

Please, if you are still having issues, test with the latest development release of Ubuntu. ISO CD images are available from .

If it remains an issue, could you 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 465319

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 .

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.

I am affected by this bug, video is working correctly, sound from integrated micrphone is not working, i will try with daily kernel and report back

oh, by the way, i'm using lucid

Now using 2.6.34 kernel and bug persists, what i realized is that after booting my pc, pulseaudio gets sound from the microphone and measures it's volume, but when i open a recording program pulseaudio stops receiving sound.
