Love the game hate the wait.
Man I queue up for op and have background sound set. Tab out do my work since Iím willing to wait. Then my toon times out and logs or the only sound that come out is a little blip when the queue is ready unlike WOW that makes it well known your up. Too frustrated on the wait times and not enough sound when its your turn. Grrrr
I turn my volume up to max and leave my character on my ship where it's completely quiet. This might work for you - provided you're wearing headphones and not using your comp's speakers.
