Custom Battle: WTF?! My sound just died!?

[Mr_Cyberpunk]

I was having fun doing a custom battle citadel siege and suddenly the sound cut out when I clicked to attack the enemy peasants that were routing (don't ask muhahaha). (the men I ordered said "Common Men!" and then the sound cut out!)

My sound card is a Sound Blaster Audigy 1, no on board sound.

So WTF?! Haven't had this happen before. Anyone else have this happen?

I had this happen, you probably pressed shift+s which mutes sound. Kinda annoying with FPS style movement.

Still happening, and this time it happened at the end of one of my Turns during the campaign. WTF?! wasn't doing it before?!
