I am having an issue, because I have a two channel external audio card, and a XLR microphone connected to the first channel, while the second channel is unconnected.

This configuration results in windows finding a stereo audio device, but audio comes only from the left channel. I'd like to know if it is possible to fix it in software, without having to build a Y-XLR cable.

The two "solutions" I can think of are either force the device to be registered as mono, or pan/mix the left channel to the right one. Or if it were possible to split the device into two "virtual devices", with one channel each.


The soundcard's drirver software does not provide too much help:

Sound card driver software


Also I can not always switch it from the application, as the applications I am trying to get it to work are things like skype, games, etc..

In applications that the audio card is "made to be used with" (DAW and other "pro"-audio work software) it is not usually a problem to fiddle with the channel however I want.

Possibly a duplicate of this, however other that the title, I am not currently sure about what he is asking.

If you can use windows native audio controls you can do the following:

  1. Go to the Control Panel (from the Start Menu or My Computer)
  2. Navigate to Hardware and Sound -> Manage Audio Devices
  3. On the Recording tab, select the recording device you are using and click the Properties button in the lower right hand corner.
  4. In the dialog that pops up, on the Levels tab, there should be a Balance button.
  5. Lower the volume of the right channel to zero.

But does it copy the left channel to the right? –  varesa Jul 4 '13 at 18:05
    
If you are not getting any audio from the right channel, why do you want to merge it? –  peanut_butter Jul 4 '13 at 18:20
    
Well I want to have either a stereo device with the "left mic channel" on both channels, or a mono device with from the left channel. So for example in skype or other voip programs the others hear my voice through both channels –  varesa Jul 4 '13 at 18:37
