Internal microphone on Vaio VGN-TT160N does not work

[Leandro]

The internal microphone does not capture any sound. All other sound
devices work, as well as the external microphone (pluged).

Hi Leandro,

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 454789

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.

Ok, I will do that. But that is my mom's laptop (which lives far away), I will probably take some time to do it.

who lives... poor mom :-)

Hello, this bug persits in Lucid. I've upgraded to lucid today on the laptop (9 may). There
is no sound capture at all from the internal microphone. Three capture options appear
on the sound preferences: microphone 1, microphone 2 and Line-in. None capture anything.

[Leandro (leandromartinez98)]

There is a long thread of VaioTT users discussing how it works with Ubuntu,
and the internal microphone problem is clearly a non-resolved issue. Maybe
the information on that thread can help:

http://ubuntuforums.org/showthread.php?t=1111753

I will mark this as confirmed, since there many VaioTT users report the same
problem and nobody found a fix.

This patch (for kernel 2.6.34) will make it work. Maybe not the best solution, but works for my Vaio TT

Alternately, can you confirm that linux-alsa-driver-modules-$(uname
-r) from ppa:ubuntu-audio-dev resolves this symptom without need for
the patch below?

No, linux-alsa-driver-modules-$(uname
-r) doesn't solve the problem. Attached is the full patch to solve the problem on stock kernel 2.6.34, including modified mixer control.

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.
