Skype Muted Microphone Issues with Ubuntu 10.10 on the Acer Aspire One.
What to do when you're unable to be heard while speaking into Skype on the Acer Aspire One.
After installing Skype onto by Acer Aspire One netbook with Ubuntu 10.10 Maverick Meerkat I was at first unable to get the internal microphone to work with Skype.
The mic would work with programs like Sound Recorder and Audacity, but after ringing the nice Skype Lady :-) who asked me to speak a little so she could play it back to confirm my mic was working, all I was met with was a low volume white noise instead of the contents of my mini monologue to her. After much mucking around and experimenting I stumbled across the solution to the silence problem and it turned out to be as simple as lowering the volume of either the left or right side of the “Internal Audio Analog Stereo” . I guess as it's a mono source, Pulse Audio currently has a problem with it being configured as a stereo input. Instead of meddling with reconfiguring the audio hardware via Pulse Audio config files and such, it's much easier instead to simply mute one side of the device via the Pusle Audio Volume Control, which is what I did.
First, you'll need to have access to the Pulse Audio Volume Control program. This can be installed from the Ubuntu Software Center as follows.
Start the Ubuntu Software Center from the Applications menu in the top panel.
Once started, type “pulseaudio volume” (without the quotes) into the search area and click on the “PulseAudio Volume Control” item which should be the first one in the list, and select Install.
You may need to type in you password and click “Authenticate” to complete the installation.
It shouldn't take very long for installation to happen.
Once it's installed you can close the Ubuntu Software Center window.
Now, to change the volume settings for the input audio, launch PulseAudio Volume Control from the Applications->Sound & Video menu in the top panel.
Once it appears, select the “Input Devices” tab.
Unlock the “Lock channels together” option,
And slide either the left or the right side volume down to silence.
Having done that, you should now have Skype happily listening to your every word.
