OK, I understand. And I agree: This is really confusing.

I am just wondering how to present this to an user. The screenshot looks so bizarre: The right channel is left of the left channel.

Right channel: PCM Out1,Right slider: 96
Left channel : PCM Out2,Left  slider: 96

And what is the "L/R Gang" switch?
