I'm having the same issue.
Any time a sound byte plays, I get a random one instead of the correct one. For instance, if I order Regulus to move, I'd expect a remark like "this would be faster with wings". Instead, I get something completely random like TB screaming "I loved them... and they betrayed me!". This also occurs for announcements like "not enough gold" or "you've captured a flag". Instead of the correct sound I get something random.
Gets really annoying.
