Internal Microphone does not work. Using Volume Control, if I unmute Mux, Mux1, Capture, Capture1, it immediately mutes itself again. I am willing to provide any details/help. Please contact me.

Thanks,

Same hardware on Dell XPS M1530 with installed Ubuntu 8.10 (released version) updated from Ubuntu 8.04 LTS.

The microphone works but at a very low level even when the Capture volume is at max, thus recording is basically not available. No mic boost option appears on the Volume Control as well. It did work perfectly though on 8.04 LTS.

If anyone could provide some info or a fix it would be great because programs such as Skype cannot be used when mic operates at such a low level

Thanks

Is this still an issue with the latest jaunty alpha? You can fetch the latest alpha live CD from http://cdimage.ubuntu.com/releases/jaunty/alpha-3.

Thanks.

Hi Prabhanjan,

Please, if you are still having issues, test with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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 282754

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.
