Clicking and Popping during recording and playback
 

Hey all,

Never had this problem before this week..

When I'm recording, I'll get popping on the recorded track that will not go way. I will also get popping on playback which is random..

When I record I set the clock to my preamp using SPDIF, again this has always worked.

When mixing, I use the internal clock.

Clicking and pops show up in bounced files as well..

Really confused.. and looking for help!
