Tron sound errors

[wishmaster_xp]

Been poking around the Tron20.net message boards, and found a whole hoard of people having the same problem I'm having.

Sounds effects play in game, but voices do not. No speech at all. >_< I've toyed with EAX speaker settings and various other sound options. Nada.
Anyone else have this problem and find a solution?

Also any status on a NoCD for patch 1.1? Don't flame me, if it's not two weeks yet! I just bought the game, and there's no mention of the patch release date on the site, so I'm unsure.
