There may be multiple problems causing audio drop outs then, because for a year and a half we have been using component cable with no issues whatsoever. Well, a couple of weeks ago, I hooked up an HDMI cable instead, and right off the bat there were audio drop outs, lasting about a couple of seconds each. It seemed to happen about every 5 minutes or so. After 1 day I switched back to component, and it hasn't happened again since.
