How could I temporarily exchange the stereo channels, the left one to the right side and vice versa? The internal soundcard is set correctly, but the USB soundcard exchanges the channels, so I want to exchange the channels.

 

May be there is a portable freeware program doing it?

You're using two different sets of sound ports? Or maybe I'm not understanding the configuration.

Keep us posted

Thank you, Dick.

 

I have an external soundcard vía USB (obviously reversing the channels), looks like a USB stick and an internal one, built in.

Seems to be an old design that doesn't list Windows 7 compatibility. Is it suppled with a driver, or does it operate as class compliant (Windows own USB Audio Device driver)?

No, there is no driver supplied, just that USB soundcard, this USB stick itself, it is the only thing supplied with the package. I have any idea if it is class compliant, but I cannot find any USB soundcard here: http://i.imgur.com/GIdpng0.png

If it's a class compliant device, we'd expect to see USB Audio Codec. Do you find a difference in devices listed when the USB unit is present/absent?

 

If it needs no specific driver of its own, I don't expect there will be any option to swap the channels. A Google search finds some unresolved questions about USB audio devices having channels transposed.

Ah, sorry, I wasn't aware the soundcard just was plugged off, it appears in the device manager (now it is plugged in): http://i.imgur.com/bzY39Zj.png

Yes, very strange, such an easily to handle thing cannot be done.

Looks like class compliant, simply uses Windows' standard driver, which as far as I know is no help with channels. A work-around would be to add a short adapter cable with 3.5mm line socket and plug, with the Left and Right connections crossed. Anyone handy with soldering could make one.
