Issue: OTA recordings of programs containing Dolby surround (i.e. 5.1) are being played back with the voice channel(s) being muted. I do hear the background noise (i.e. typically music) though. If I select PCM in the TIVO Audio settings then I can hear the voices as well. My A/V Receiver indicates that the audio stream from EDGE is 5.1 when TIVO Audio setting is 'Dolby' and is 2.0 when TIVO Audio setting is 'PCM'. I also have many previous OTA recordings that played back correctly with 5.1 sound before this issue started occurring, but are now playing with the voice channel(s) being muted. I have been monitoring the recording of our usual programs (i.e. CBS, NBC, ABC, FOX) and some programs are exhibiting the voice channel(s) being muted. The issue is very random (i.e. CBS ok on one program, but not on another CBS program). Question: Does the TIVO EDGE Audio setting only apply to the audio being output from the TIVO box, and that the audio being recorded from the OTA program is not affected(i.e. raw audio stream always recorded)? Has anyone experienced this issue? Any recommendations on how to resolve the issue?
