Hey guys, I'm having a real frustrating problem. Getting a crackling / popping sound whenever I record or monitor guitar or bass. Now, I know this is a problem when your buffer size is too low, and it's something that generally happens to me every once in a while. Normally I can fix it by just re-initializing Core Audio, but this time, nothing I have done has worked. Here are my specs:

2007 Macbook Pro
Intel Core 2 Duo Processor, 2.2ghz, Dual Core
2GB RAM
Presonus Firebox (Firewire interface)
Logic Pro 8

Now here's what I've tried so far:
-Closed all other programs
-Re-initializing Core Audio
-Changing buffer size in Logic
-Changing sample rate in Audio/Midi settings
-Restarting Logic
-Restarting computer
-Installing updates and restarting computer
-Changed guitar cables
-Changed guitars
-Tried new tracks, problem occurs with dry signal, no overloaded effects
-Bypassed my interface completely by plugging directly into computer's Line In, still there

I can play sounds from other programs, and even play software instruments and synths with MIDI, no problem, but when I record any outside instrument, there's that annoying crackling noise. Any ideas guys? Thanks in advance.

You're either overdriving the microphone or the input to your DAW. Digital is very unforgiving when it comes to overdriving the input.

Can you post a sample?

I don't think it's a clipping problem. Levels on everything are well under the danger zone, and I've recorded with my levels this way numerous times, no problem. The crackling is like a dusty vinyl record, only constant and occurring on everything I play.

Will post a sample shortly.

Edit: Here's one.
