Hi everyone I've just installed Windows 7 on this PC but I'm having a very strange problem with the sound. I have an X-fi XtremeMusic PCI card which has worked fine in my old PC for years running on XP. Since installing Windows 7 the sounds are coming out very peculiar. Normal windows sounds which I guess are probably .wav files play perfectly, very clear and audible. When I try and play a .mp3 file however the main vocals of the track sound as if they were recorded with the singer about 100 yards away from the microphone. Certain instruments sound kinda normal but some of them are like the voices and very far away. I get exactly the same effect trying to play an audio CD. I have tried the inbuilt media player, creative media player and foobar mp3 player. All give the same effect. When I try and play HL2 most of it sounds fine but I can only hear the characters speech if I am facing away from them! If I face towards them it becomes very very quiet. I have installed the latest Windows 7 drivers from Creative (these are the first drivers I tried). Then I tried some old Creative Windows 7 Beta drivers and got exactly the same thing. All this time the onboard audio of my motherboard was disabled. So I then tried enabling the onboard audio and installed the latest drivers from the ASUS website. I got exactly the same problem I really don't understand what is going on at all. Especially because normal windows sounds come out fine but just certain sounds within all my mp3's along with the HL2 issue. I'm using headphones but they work fine with other devices. Anyone got any ideas?
