Internal Microphone on Dell Lattitude e6410 does not work

[Walter Garcia-Fontes]

The internal microphone does not seem to work. I don't get any input from either Micro 1 or Micro 2 from the gnome mixer. Plugging in an external micro works.

I tried the solution suggested in :

http://ubuntuforums.org/showthread.php?t=1504774

and it did not work for me.

[Walter Garcia-Fontes (walter-garcia)]

Sorry, the solution in #2 DOES work, it seems I forgot to restart after applying it. But if it is just a workaround I guess the bug stands.

[Luke Yelavich (themuso)]

There are several posts with several things to try in that thread, as well as several people asking about their different hardware models. Could you plesae point me to the post that fixes your issue?

Thanks.

[Walter Garcia-Fontes (walter-garcia)]

What works for me is comment #5:

[Fabio Gori (igor-fobia)]

I have a similar problem with my Dell Latitude E4300. I read that the internal microphone it is a digital microphone
http://forums.opensuse.org/english/get-help-here/multimedia/440083-skype-mic-problems.html

So I began to tune my alsamixer setting. I still have some quality problem, but I had no time to try all the options properly.

A snapshot of my alsamixer config is included.

[Luke Yelavich (themuso)]

Since the package is set to alsa-driver, the relevant people will see this bug.

[David Henningsson (diwic)]

So this is basically the same three-mics-problem as bug #519066 .

Takashi fixed it a few days ago, so according to my own simulations https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules would solve this problem. Can you verify?

[Hankyone (hankyone)]

I can confirm, problem solved.

[Pedro Villavicencio (pedro)]

assigning the bug to David for now, thanks all. btw a patch was proposed by him on bug 628961 https://bugs.edge.launchpad.net/ubuntu/+source/alsa-driver/+bug/628961/+attachment/1540716/+files/0001-ALSA-HDA-Enable-internal-mic-on-Dell-E6410-and-Dell-.patch

[Leann Ogasawara (leannogasawara)]

This is fixed in Maverick as of 2.6.35-22.32. Thanks.

Just installed Maverick release candidate:
Linux delle6410 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:32:27 UTC 2010 x86_64 GNU/Linux

The internal microphone works perfectly without the workaround in #2 and #3. Great job everybody!

[Martin Pitt (pitti)]

Accepted linux into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Steve Conklin (sconklin)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by Thursday, November 11, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Walter Garcia-Fontes (walter-garcia)]

My systems right now are all updated to Maverick. Is there a kernel that I can test in Maverick? Otherwise somebody still with Lucid should test.

[Steve Conklin (sconklin)]

Due to national holidays, the deadline for verification of fixes for the -proposed kernel has been extended thru Monday, November 15th.

If verification that this bug is fixed by the -proposed kernel has not occurred by that date, the change will be reverted and this bug will be set to incomplete.

If you have tested the kernel in -proposed and found that it fixes the bug on the original hardware, please change the bug tag "verification-needed" to "verification-done".

The new stable kernel release process under which these actions are being taken is still being refined, and is documented here:

https://wiki.ubuntu.com/Kernel/StableReleaseCadence

Discussions about the new process tend to take place in #ubuntu-kernel on IRC, so please contribute to the discussion there if you would like.

Thank you!

[Marc Tardif (cr3)]

I have a Dell Lattitude e6410 with 10.04.1 and the proposed kernel, 2.6.32-26-generic i686. There is no input device listed under the sound preferences, so microphone doesn't work. For completeness, I tried to report a bug with the command "ubuntu-bug audio" but this raises an exception when attempting to read /proc/asound/cards which doesn't exist.

[Walter Garcia-Fontes (walter-garcia)]

Marc: if you could try the kernel suggested by Steve in
https://bugs.launchpad.net/ubuntu/lucid/+source/linux/+bug/605047/comments/20
it would be great, otherwise I will have to install Lucid again in a partition of my E6410 laptop just to try it, since I have updated already to Maverick.

[Marc Tardif (cr3)]

I have the latest kernel from the lucid-proposed repository, please let me know which kernel version you are referring to.

[Walter Garcia-Fontes (walter-garcia)]

To the one that you can see if you follow the instructions in https://wiki.ubuntu.com/Testing/EnableProposed (changing Maverick to Lucid). I may try to test it anyway this weekend setting up a special partition for Lucid in my E6410.

[Steve Conklin (sconklin)]

Verification that this bug is fixed has not been completed by the deadline for the current stable kernel release cycle.
The change will be reverted and this bug is being set to incomplete.

In order to have this fix considered for reapplication to the kernel, please follow the process documented here:

https://wiki.ubuntu.com/Kernel/StableReleaseCadence

Discussions about the new process tend to take place in #ubuntu-kernel on IRC, so please contribute to the discussion there if you would like.

Thank you!

[David Henningsson (diwic)]

@Marc, I don't really know how your system managed to screw up so badly that you don't even have a /proc/asound/cards file - perhaps you installed a non-working ALSA driver override? Switched to OSS? Perhaps there are some hints in dmesg of what can have happened?
Thanks for the report of ubuntu-bug audio not working - I'll try to fix that up, at least for Natty.

[Øyvind Stegard (oyvindstegard)]

Fix worked fine before it was reverted (Dell E6510). What do you need besides "It works for me and does not break anything else on my machine" to get it through the verification process ?

[Øyvind Stegard (oyvindstegard)]

I cannot confirm that it fixes it on original hardware, since I don't own a Dell E6410. However, like I just stated, at least it worked for the Dell E6510.

[Øyvind Stegard (oyvindstegard)]

Setting stable-reapply-lucid, as instructions on https://wiki.ubuntu.com/Kernel/StableReleaseCadence say.
Will verify fix for next update.

lucid has seen the end of its life and is no longer receiving any updates. Marking the lucid task for this ticket as "Won't Fix".
