I am having trouble setting up two new playbases, both of which do not play any sound from a hdmi device connected to the TV (both are Rokus). The playbase works fine with antenna TV stations, so I know the optical connection is good, and the TV speakers can play audio from the roku devices. I have tried every audio setting on the roku, including PCM-stereo, Dolby, Dolby+, DTS, and DTS+, to no avail. I have read there might be issues with the TV passing 5.1 audio from HDMI inputs to optical due to HDCP, but I thought I would at least be able to hear 2.0 audio from the Sonos. Does anyone have any suggestions?
My TV models are Sony KDL-40V2500 and Sony KDL-46S4100
