My MB has suddenly started emitting an echo sound on all audio. i noticed it first whilst using logic and thought i must've had a delay plugin instantiated, which i did not. i then tested on itunes, quicktime player and all other audio generating programs... the echo is on everything. it's not a massive echo, but it is clearly noticeable when i have instruments or drums soloed in Logic or am auditioning sounds in finder. Obviously i cannot continue to produce music on the system whilst this problem remains.
I have bootcamp on the MB also and the problem does not exist when running audio programs in windows.
Any ideas??
