Hi fellas,
i`ve one hell of a problem. AT works fine on my new pc but when i try to run it in the background there is no sound. As i often played on my old machine with AT while running guitar pro in foreground i tried it with my new machine but the guitar sound is directly gone.Even if i'm running AT alone and set it in to the taskbar it quits sound.
I've already tried the search but didn't find any hints...... so any ideas?

Regards, Ron
