New member here in need of some help. I've spent the last week trawling through the forums here and on the Virgin website, but can't seem to find a solution for my issue. My suspicion is that the problem is with Virgin, but I am posting this here in the hope someone might have already been through the same.
My setup: I have a Virgin V6 box and a separate media player (NUC) both connected directly into my TV (Sony KD77A1) via HDMI cables, to HDMI input 3 (ARC) and HDMI input 1 respectively. The TV is connected to the Sonos Playbar via an optical Toslink digital audio cable, as part of the Sonos 5.1 home theater system.
My problem: I only get stereo sound out of the V6, irrespective of the channel (SD, HD, 4K, etc).
Further details: The V6 audio output option is set to Dolby Digital (but I have experimented with PCM as well, to no avail). The Sony TV definitely passes through Dolby Digital via the optical cable. Indeed, I get full 5.1 surround sound out of the other media player in this setup. I have tried swapping the HDMI inputs between the V6 and the other media player, to no avail. The HDMI and optical cables are brand new and high quality (and, again, the fact that the other media player outputs 5.1 surround suggests none of the other components in the system are at fault).
All roads lead me to believe the issue is with the audio output from the V6 box.
Any idea how to get 5.1 surround sound from the V6 to the Sonos playbar?
Many thanks in advance for your help!
