Creative SoundBlaster X-Fi Fatal1ty Issues - Fedora 13 64-bit

I've browsed around for a while now and searched quite a bit and I'm either blind or unable to find anyone with a similar issue to mine:

After installing Fedora 13 (64-bit) my audio works but it's intolerable. The sound crackles and pops and echoes and does all kinds of strange things while listening to any sort of sound (system sounds, mp3s, video). I was going to install the driver from creative's website; however, doing so resulted in the following errors:

# make

I've also tried playing with the input/output settings in the PulseAudio volume control panel, but my sound either got quieter (still popping though) or ceased working. My speakers are 5.1 and I do have a mic plugged into the flexijack (but I don't care if the mic works or not under Linux).

I'm dual booting Windows XP and recently I tried to upgrade to Windows 7 64-bit. I ran into the exact same sound issues in Windows 7 so I reverted to XP where my sound works great. I'm lead to believe it's a driver issue given the evidence but I have seen several other posts on this forum from people using the same sound card and version of F13 but not having this issue. Maybe it's a conflict somewhere?

Please let me know what other information I can provide to help troubleshoot this.
