I am recording the video using logitech camera and bluetooth microphone. Logitech can used for recording both audio and video.

When I turn on bluetooth microphone in the middle of recording, it is replacing the logitech audio channel due to this we are getting the bluetooth audio from the left channel.

But when I turn off the bluetooth then I get the logitech audio on left channel but the volume is very low and also getting the some noise.

I am using PulseAudio and ffmpeg for recording purpose. So how can I increase / change the volume of left channel during runtime?

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
