Apologies if this is covered elsewhere but I/ve not been able to find a suitable solution when searching. (Maybe I'm seraching for the wrong words).
I have a Virgin Media Tivo box connected to my TV through HDMI and the Optical audio output of the TV connected to a SONOS Playbar. I would like to connect 2 further speakers to the Playbar in order to produce a surround sound set up. However, the TV does not seem to be outputting a Dolby compatible signal, only stereo.
What settings do I need to make on the TiVo to enable the Dolby audio output through the HDMI to the TV?
Looks like there is some other issue going on. When I select the TiVo input on my TV, the info panel shows it is receiving "PCM" audio. The audio settings of the Tivo show Dolby and not PCM. The TiVo is connected via a HDMI lead which is connected to an ARC enabled socket. Is that correct or is ARC interfering with the Dolby signal.
