2nd: I already have Fallout 3 with all addons, and it still works perfect - without any Glitches or anything else
And now to the Topic:
I've got the Game today, Registered it on Steam - it downloaded the newest Patch, and i started the Game.
it worked fine, until it came to the first Conversation with the Doc: i saw his Lips moving, but no Sound came out.. then his Lips stopped moving, and nothing happened.
I waited for the next Minute, and still - Nothing happened. So i went to the Menu by Pressing ESC, and back to Game (the Same way ^^)
Suddenly, the Lips of the Doc moved again, and i heard his Voice.... The first Sentence came (I thought you never make it oder something like that)
Then the game went Silent again. And The Sound came only back, when i left the Game for the Menu and got back to game. FOR the next sentence
So (to make it Quick) i can only her a Person speaking (for only one Sentence), if i press ESC during the Talk. And i even hear the Gunshots ONLY after i get back from the Menu.
I Noticed that (when i was lying on the Bed in the Doc's room) there seems to be a Endless Sound-loop that repeats every 2-3 seconds. And when i Press ESC some Other Sound file gets in the Loop.
My System:
Windows XP SP2 (i also tried it with SP 3 - same thing)
AMD Xp 3200+
Soundblaster Live! 1024 (latest Drivers)
ATI X1950 GT 512 MB with Catalyst Ver.: 10.2
2 GB RAM
Here ist the DX-DIAG (in German): http://www.fileuploadx.de/308496
I dont know if this Problem is known, but -cause the Game is unplayable for me - so i hope, it will be fixed in the next Patch
