Have Asus Rampage Formula mobo with sound card. Have FSX sounds going through speakers and voice going to headphones through front panel. Start flight, open ATC, contact ground, request taxi clearance, get clearance - so far so good - all sounds as expected and messages print and scroll in ATC dialog box. Taxi to runway, select contact tower and option for request takeoff clearance shows - now whether I press the number or click the selection - nothing happens except the selection blinks - no sound, no scrolling message - nothing. Dialog is not dead because if I select something else, the options change but no sound, no action takes place.
Tried sound acceleration on/off - no change.
Tried the old fix of switching between COM1 & 2 and back - no help.
Meanwhile all other sounds function as expected.
Anyone seen anything like this before?
Thanx,
Vic
