I have had that same experience with audio sync issues. An annoying, but helpful trick:mitzkity said:Yes, I called them and reported it - they said it's a known problem at the station with HD transmissions and they are working on it. Thanks for your help.
Hit your 10 second back button. This usually syncs up the a/v again. There were tons of issues with the KCBS HD here in So Cal last night.
