Definitely not my week, a new problem; Another project I'm doing is comprised of audio narration with photo images as visuals. Somehow, yesterday the audio VO became clipped, every 2 seconds or so. I had some images that had to be reconnected also.
I tried audio in Soundtrack and same thing, clipped audio. And another issue came up, I went to Garage Band and same clipped thing on some (not all) of the music clips. Very odd.
the audio was choppy, sort of like static every 2-4 seconds, could only hear bits of words. I called Apple tech who asked me to go to youtube and see if it was also choppy audio. It was so he surmised it was a bad sound card and made appt at a local Apple store.
Last night I had an update for flash appear and I updated it and audio became normal again. Don't know why it was choppy and clipped and why it went away with flash update. But for now it works fine.
