Regression, system does not capture sound from microphone

[palexv]

Binary package hint: pulseaudio

Looks like its a regression on 10.04.

1. Boot Karmic 9.04 LiveCD (Kubuntu). Install skype, turn up all bars in KMix. Make test call - skype works well, it hears my voice.

2. Boot Lucid Lynx 10.04. Do the same - skype does not hear my voice. At the same time I can hear my voice in headset in real time. But for some reason it does not be recordered.

Tried:

1. Install pulseaudio - no effect

2. Installed linux-backports-modules-alsa-lucid-generic, no effect.

3. Tried to set mono input using pavucontrol - no effect.

Fixed it!

1. Added http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu to sources list

2. sudo apt-get install linux-alsa-driver-modules-$(uname -r)

And it works!!! It took me 2 days to figure out.

Guys, this should work from clean install. Its very bad to waste days to figure out such single thing as record from mic.

[Sammy (oilej)]

I had exactly the same problem (Samsung, HDA ATI SB, Realtek ALC262, microphone not working) and the same solution (worked after reboot). I suppose there are more people struggling with this problem (e.g. http://ubuntuforums.org/showthread.php?p=9245616). HOW did you figure it out? Thanks a lot!

[ChrisC (chrispche)]

That fix has not worked for me.
 I get:

chrispche@chrispche-laptop:~$ sudo apt-get install linux-alsa-driver-modules-$(uname -r)
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package linux-alsa-driver-modules-2.6.32-22-generic
chrispche@chrispche-laptop:~$

Any idea's?

[palexv (palexv)]

First do

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa

then

sudo apt-get install linux-alsa-driver-modules-$(uname -r)

[palexv (palexv)]

Forgot to update. Do following

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
sudo apt-get update
sudo apt-get install linux-alsa-driver-modules-$(uname -r)

PALEXV-You are a genius! I've been fighting with this for almost 3 weeks. I finally got my microphone working! I've spent actual days reading every post I could find-nothing worked til now. Thank you very much.

Did not work for me :(

[ajdoakwood (najd2)]

Brilliant, it worked, I've been unable to fix this for the last 6 months, and thought upgrading to 10.04 would help - it didn't and I was taken by surprise when this solved the problem. It's a pity this page is so obscure - there are dozens of false trails which
came up before this on every search I did.

[madbiologist (me-again)]

Does this still occur with the kernel in lucid-proposed?

[ticket (tickettothemoon2004)]

This fixed it for me:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/474359

but with a slight difference:

  install linux-backports-modules-alsa-lucid-generic and reboot.

(ie. lucid, not karmic, as I am using lucid).

I had previously upgraded from karmic to lucid (didn't do a fresh install of lucid). The problem might not arise on a fresh lucid install.

I have a P7P55D EVO motherboard.

[Mohammad Alhobayyeb (mih1406)]

I have the same problem.

I tried these steps:

Install alsa-oss then removed since nothing happened.

Installed linux-backports-modules-alsa-lucid-generic and reboot then removed since nothing happened.

Please I need help.

[Andrea Paone (a-paone)]

Thanks, palexv! It worked for me.

[adrian dumitru (adum68)]

Worked for me, too. Required one additional step though: from Applications --> Sound & Video --> PulseAudio Volume Control --> Input Devices (or start pavucontrol in a terminal), I had to mute the right channel of my internal audio/microphone. Click the lock to prevent any changes, and disable auto adjustment of microphone levels in skype.

By the way, these steps solved similar issues I had with the new "make phone calls" feature in gmail (possibly with gmail video chat as well, need to check).

[João Miguel Lopes Moreira (jmlm-1970)]

The only solution to make microphone work is to install linux-backports-modules-alsa-generic...

Just go to:

Menu / System / Administration / Synaptic Package Manager

And search and mark for installation:

linux-backports-modules-alsa-generic

tip: if you have multiple versions click on the first and read the description which should inform what name to install...

If after the reboot and mic mute is off, still does not work, just go to terminal and type:

sudo nano /etc/modprobe.d/alsa-base.conf

and add or change the following:

options snd-hda-intel model=auto enable=yes

Then Ctrl+X, type Y to write and exit, reboot and mic will work.

Bye and have lots of fun with Ubuntu (the best).
