I recently bought two extra monitors and they both have stereo speakers.One is on the right of my main monitor and the other one on the left.They are set up as two different stereo setups (renamed to right/left monitor respectively)
I would like to configure them so they are one stereo output with the right audio channel playing through both channels of the right monitor, and the left audio channel playing through both channels of left monitor.
Any help with this would be great, I'm fine with extra software as long as it's free. (I must still be able to switch to my headset).
