Hi everyone, Has anybody had this issue with the UB version of Doom 3? After I installed the Doom 3 1.3 Rev A update, the sound didn't work at all! It worked perfectly on my friend's iMac (BTW, it runs brilliantly on the 20" core duo with 1.5GB RAM, on Ultra settings), and not on my 2GHz MB, with 1GB RAM. Even when I connect external speakers or earphones to it, it doesn't work. Any help would be appreciated.
