Crackling noise from USB 2.0 audio interface
Whenever I play back audio via my Edirol UA-25 interface I hear random crackling noises.
This happens with pretty routine material - e.g. simply playing an MP3 file using Windows Media Player - not just when attempting to monitor complex multi-track arrangements.
This doesn't happen when I'm using the computer's bog standard built-in soundcard so it can't be the computer itself. I've checked my monitors and studio control matrix with non-computer audio so they can't be responsible for this issue either. It happens when I'm monitoring via headphones too.
I'm using Windows Vista but I get the same problem with XP as well.
Any suggestions on how I might address this issue?
