So I was driving and a google hangout calls came in. I answered it and hanged up. After that, my audio system turned all sound coming out into "tock tock.... tock tock tock...tock.....tock...". It doesn't matter if I stream from bluetooth, or listen to internet radio, or streaming. You can tell it is trying to play the sound but everything turned into this morse code like knocking sound. When I got home, I reset the MCU and everything went back to normal. Anyone seen this before? I wonder if I could reset MCU while driving. It was pretty boring without any audio on the drive home. I guess I could get off the freeway to reset MCU.
