When I pause playback and then start it again, the video resumes immediately but it sometimes takes about five seconds before the audio starts again. When the audio finally does start, it's always in sync with the video.
This only happens with an optical audio cable to my amplifier, on both live TV and recorded shows. It happens about every other time I pause playback, but sometimes it works normally, with both audio and video resuming immediately after hitting Play.
It does not happen with RCA red/white cables to the same amplifier. It also does not happen on my Series 3 TiVo with the same optical cable and same amplifier.
I've also discovered that it only happens when Dolby audio is enabled on the Roamio. It does not happen when I select PCM.
First, has anyone else seen this?
Second, I have a Sony 5.1 amplifier with Dolby, so I assumed I'd want the TiVo to be set to Dolby as well. Will I still get 5.1 sound if I use PCM? What, if anything, will I be losing?
