[pulseaudio-discuss] Recording from USB devices without channel mixing

[Klaus Jaensch]

Hello,

we use USB audio devices (e.g. M-Audio Fast Track and Focusrite Scarlett 
2i2) to record mono speech on Ubuntu.
We face the problem that for mono recordings both input channels of the 
devices are mixed together. But we want to record only the left channel, 
not the mix. The left channel gets only half of the dynamic range; the 
signal amplitude does not exceed -6dB.

Is there a way to configure PulseAudio accordingly?

Regards,

Klaus
