Audio channels already in use

[Chieluzz]

I'm using the ECHO AudioFire12 audio interface.
For my windows sounds, I'm using output 11 and output 12 from my audio interface.
For the Cubase MASTER output I try to use output 11 and 12 as well.

In windowsXP, there is no problem. Everythings working fine.
But under Windows VISTA64, there is a conflict.

Cubase gives me the message:


The following channels are in use by another application

Analog 11
Analog 12

Audio output drom these channels will be muted.

Is this something from VISTA or from Cubase?
Is there somthing to do about this?
