Advertisements I use Plex on my Roamio, Bolt, and Minis every day. It seems that just recently (can't figure out exactly when), the Tivos have all started passing only 2 channel PCM to the receivers. I know for a fact that they used to pass 5.1 Dolby Digital. I have made sure that 'enable AC3' is selected in the settings for each device as well. I have also verified that the TiVo still passes DD5.1 to the receiver while viewing other sources. When looking at the Plex server, it shows that it is transcoding the audio to AAC. Has anybody else noticed this change recently? I am not sure if this is Plex player issue, a Plex server issue, or a Tivo issue?
