Recently, I installed the X-fi Titanium PCI-E card. Everything sounds great and my mic works well in other programs and games, however, when talking in ventrilo there is a noticeable high pitch microphone hiss. The hiss goes away when I put my fist around the mic, but I can't exactly talk like that. Plus putting foam around the mic doesn't make it go away.
The headset works fine on other setups so it is not at fault. It's almost like there is a mic boost on, but there doesn't seem to be a mic boost feature in the Creative Console.
Windows 7 Home Premium 64-Bit
Intel Core I7 920 @ 3.4ghz
Asus P6T Deluxe MOBO
Creative Sound Blast X-Fi Titanium PCI-E
Any ideas. I've tried everything. I used to exact same ventrilo settings on another computer and have had no problems, so it is not ventrilo and is not the mic. It has to be something wrong with the sound card.
