I have a similar problem after installing 1.2.
We had a pair of matches with some friends last night on my home LAN with their pc connected in local and we were all experiencing wierd behaviour of all sounds and voices.
One of my friends had the TB and he was getting the "My inventory is full" TB voice every time he killed a demigod, for example.
The other was getting the whole speech that the narrator tells you when you finish the singleplayer tournament (that one that ends with "...you are now a God!") during all the match, continously.
The Tower is making a very silly sound when it dies...like "uhhhhhh" very funny to hear I'll say, I won't tell you what it reminds me of 
The speaker keep telling "the forces of light needs 1 kill to win" but we were playing conquest mode.
Things like that, in general very bad behaviour of all sounds/voices on all 3 clients, we also experienced sounds loops like Regulus apparent new ability "noise you to death": his crossbow firing sound repeating endlessly.
For reference I had the UB and the third mate the Tower.
