Google Talk/Skype will not transmit my voice. My microphone works in sound recorder, and i can see levels moving when I check sound settings in gmail.

How do I fix this

If I'm not mistaken, Skype has a setting that automatically adjusts your volume levels. – Cumulus007 Jul 29 '12 at 21:50
I see that it does. And that has solved my problem. Thank you. – Fawkes5 Jul 29 '12 at 21:58
I think the question im more interested in now is why do i have to put one channel to zero and the other to something else? – Fawkes5 Jul 29 '12 at 21:59

This solution solved my problem:

1) Install Pulseaudio Volume Control

2) Go to Input Devices Tab

3) Make Left[Right] channel zero and Right[Left] channel non-zero. Adjust it to suit yourself.

Now everything works.

However, Skype and google talk have auto-adjust features that are turned on by default. These will turn the channel you set to 0 to something non-zero and nothing will work any more. So you have to turn these off.

In Skype, go to options, sound devices and uncheck "Allow Skype to automatically adjust my mixer levels".

Google talk is more complicated as there is no box to uncheck. The following will do it,

1) use your favourite text editor to edit the file ~/.config/google-googletalkplugin/options

2) Change the value of audio-flags to 1

Restart your computer and that should do it

Hope that helped
