Hmm Annoying problem

[Intense]

Hello,

I never had this problem it started like 1 week ago suddently.

i run on: Direct sound / input device: realtek AC97 Audio/ output device: realtek AC97 Audio

now the problem: when i join ts they can hear me no problem,clear,nice etc. but when i join my game : Counter-strike:Source and i join a server, they can't hear me anymore

To fix this i found a annoying solution: i change my output device to Peripherique Audio Principal then everything works fine again.. and after a while of playing it stops working to and i have to RECHANGE it output: realtek AC97 Audio so they can hear me,

Could anyone Pleas help me?

Try updating your drivers and check to see if you have direct selected in the TS options.
