Vitaly Volkov, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.19-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

[penalvch (penalvch)]

Vitaly Volkov, the latest mainline kernel is 3.19-rc1 (not 3.14.x, 3.15.x, etc.).

[Vitaly Volkov (hash3g)]

I have "trusty" installed, mainline page here http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D does not contain kernel 3.19 for trusty.

[penalvch (penalvch)]

The release names are irrelevant for the purposes of testing.

[Vitaly Volkov (hash3g)]

Ok, installed latest rc2 - internal microphone does not work.

[penalvch (penalvch)]

Vitaly Volkov, just to clarify, did you originally report this using the terminal command:
ubuntu-bug -s audio

or did you file this manually via:
ubuntu-bug linux

[Vitaly Volkov (hash3g)]

ubuntu-bug linux

[penalvch (penalvch)]

Vitaly Volkov, could you please report this via:
ubuntu-bug -s audio

if it brings up reporting against linux, you may just cancel before actually creating the report. However, if it is going to file it against alsa or something else, please do make a new report and mention this here.
