I'm running win7 pro 64bit. The sound is crackly, screaching, or just doesnt work at all. Also, my mic doesnt work at all or sends the crackling and screaching to the recieving party. Ram:4gb Processor: intel core 2 cpu 6300 Soundcard: Creative X-Fi XtremeGamer Fatal1ty Pro Series Soundblaster I have tried uninstalling, reinstalling, restarting, disabling, new drivers, old drivers, fixers, etc. Nothing I have tried is working. I'm running split partition xp/win7 pro. On XP OS my sound is perfect, I have used the same exact settings on both OS's with no luck, i have tried tweaking it, I've tried randomness. I'm in need of assistance, please help.
