I have a »HP Pavilion 500-205t CTO Desktop PC with 64bit Windows 7 and IDT High Definition Audio CODEC. I can provide more stats if needed.
The problem started around Memorial Day (May 26, 2014). I began to hear an occasional crackling or popping sound that would come through both speakers and headphones no matter which jack I used. This problem got worse until it popped every few seconds and was intolerable. When I restarted the PC, the problem disappeared for 12-48 hours before returning again. It always begins with just an occasional crackle or pop every now and again and progressivly gets worse as mentioned.
My audio and video drivers are both up to date. I've tried disabling my wi-fi to see if there was intereferance from that, no luck. I've also plugged the PC into different outlets and used different power strips. I removed all other electronic devices from near the PC. The problem occurs across all playback devices (WMP, video games, youtube, spotify, etc). Any help is appreciated!
My dxdiag is attached.

Moved to 'Audio and video', then to Internal Hardware.
