How to stop Google Talk Plugin auto adjust Microphone volume ?! DukElec 8/26/10 12:04 AM
Explain your issue in full detail here:

I want my Microphone volume fixed.
because the Volume Adjust Algorithm is most unsatisfactory, the volume always set to 100%, and then can't hear anything except beat noise.


Please Also Include:
Operating system (e.g. WinXP): Ubuntu 10.04 x64
Program and version you use to access Gmail (e.g. Internet Explorer 7 or Outlook 2003):  Firefox 3.6.8
Your antivirus software (e.g. Norton 2007): none
Any extensions, toolbars or plug-ins: none

Hi,

A few posts have been about Linux microphones. In particular the auto level adjust feature that google chat uses. Others, who have had issues with the internal mic on their laptops/notebooks read on too....

This auto adjust CAN be tuned off.

My symptoms are: for the internal mic to work the left mic channel must be turned down to zero and the right channel set to the desired level. Google talk however automatically adjusts both channels to what it thinks is optimum.

To see the mix channel settings use PulseAudio Volume control and go to the input devices tab. PulseAudio Volume control is in the Linux menus under the sound and video submenu (on Ubuntu anyway). You may need to install the package pavucontrol to get this gui.

To turn off the auto adjust:

cd ~/.config/google-googletalkplugin    # get to google chat's directory
cp -p options options.bak        # make a backup before changing stuff !
gedit options                # edit the config file

now change one of the lines so that it reads as follows:

audio-flags=1

Now restart you machine and google chat will no longer auto-adjust!!!

Remember to go to PulseAudio volume control just to make sure the left channel stays at 0

Thanks very much . I'm DukElec , I can't find the file "options"  in  folder " ~/.config/google-googletalkplugin" , but I creat a new file named "options" , and just put line "audio-flags=1" in it , it can work ! ^_^

it would be nice if it were that easy in windows.. what a nuisance auto adjust is. using the browser plugin really sucks, but the service is great. if someone can disable it in XP thatd be slick too. :)

The above workaround didn't work for me.
I'm using Arch Linux with KDE 4.6 SC, Gstreamer backend with pulseaudio and Firefox 3.6.13. Plugin version is 1.8.0.
Setting "audio-flags" to 1 still make the plugin auto-adjust the volume.

Please notice that other apps (like skype), with left channel turned down to 0 and auto-adjust switched off, work fine.

What exactly the audio-flags option controls? Cause I tried to set it to 0 as well, but no luck again.

Thanks for any further help!

Update: setting "audio-input=Audio interno Stereo analogico" instead of leaving it blank for default, and setting "audio-flags=1" seems not to lock channels anymore.
Anyway, input volume seems very low. I'd try ASAP to talk with some one and test it.
