This isn't a driver problem (for me), because I have the same cracking sound using the onboard sound card AND using different USB sound cards.
The problem occurs in any music player (in Windows Media Player, or Winamp).
The sound crackles and stutters when the CPU is busy. That is, when I open a Web page, or start a program, I hear pops and garbled sound if I’m playing music.
Here's what I've tried:
Installed the latest drivers.
Tried using 2 different external sound cards.
Installed the Codec lite pack .
Disabled speaker effects (enhancements).
Reset the BIOS to the factory default settings.
Flashed the system BIOS
A reboot fixes the problem, but then it eventually comes back.
I hate this because I love listening to music while I work.
Thanks LOADS for any suggestions!!
