Hello guys are in possession of the Logitech G35 USB, the problem is that the game does not find them, I do not hear the audio
headphones and even the microfone work, you too have this problem? know to solve it? Thanks

I have experienced this issue with other games. I have always used a USB headset, but when I added a set of external speakers to my PC and therefore a second audio device, I lost the use of my headset. I use Vista and the only solution I found was to disable the audio device (external speakers), so that Windows only thought I had a USB headset for sound. Rebooted and all was good. If you also do this, be sure to hide your inactive devices if you have Vista. If you don't hide the inactive devices, Vista may provide some meaningless error message on every boot. Hope this helps.

G35 headset works for me, have you installed the headset drivers correctly?

thanks guys the problem was resolved.i explain better the drivers were updated this I am sure I
Following the advice of Stunodand now the g35 is now working .THX

I'm not having a problem w/ Crysis 2. It's already been said you should check your drivers. Also make sure that the default audio device hasn't changed in control panel for whatever reason (this did happen to me a couple of times).
