Hi everyone, I just wanted to see if other people are experiencing this same issue. Ever since upgrading to Mountain Lion, my Bower & Wilkins MM-1s have been intermittent through the USB part of them. I've tried the following: Removed the soundpreferences plist from ~/library/preferences, then restarted. Tested in new user--occurs there. Ran the Apple Hardware test. SMC/PRAM resets. Tested on other computers not on Mountain Lion. They work perfectly fine. Anyone else experiencing this?
