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.
