Crackly sound (not voodoo or hda)
I have installed Lion twice now. I actually had to buy a sound card especially for Lion because I could not get any drivers to work at all for my onboard sound. The first time I installed Lion I found a kext that would work for my sound…

I have installed Lion twice now. I actually had to buy a sound card especially for Lion because I could not get any drivers to work at all for my onboard sound. The first time I installed Lion I found a kext that would work for my sound card. It worked flawlessly. I deleted the installation because my apps weren't running correctly. I later found out I didn't do the xpchelper fix, just deleted ReportCrash. I did that right this time. The second installation I installed the same next and my audio is crackly. I don't know what's different this time… I've searched and all I can find is people asking this question about VoodooHDA, which I am not using. What could be causing this?
Sound Card: Diamond Xtremesound 5.1
Kext: CMI8738PCIAudioDriver.kext
p.s. i tried the midi application and it's on 16-bit which I can't change and 44100 which is the lowest. Both options I get I get crackles.

I think it's a non-driver related problem. I found a USB sound interface and plugged it in and the output sound sounded the same.
edit -- Figured it out. I didn't have my BusRatio specified in my boot plist. Audio is perfect now and also the system seems to be running smoother.
without you posting your pc specs not many people can try to help
