brucecampbell Posted May 25, 2020 Share Posted May 25, 2020 I tried some Dolby sound tests on YouTube. The surround channels are coming out my front speakers. Yet when I watch movies we do get surround sound. I got the same results using Roku, AppleTv and the actual Panasonic smart tv. Not surprising given they all provide sound to the receiver via the tv’s single digital out. Receiver is HK AVR255 which defaults to Logic 7. Is this logic 7 getting in the way or am I probably not actually getting Dolby 5.1 when watching anything from these sources? Cheers.

brucecampbell Posted June 1, 2020 Author Share Posted June 1, 2020 Upon further testing, My receiver says PCM 48 when I turn on the TV as the source. TV is the audio source for ROKU. ROKU to TV via HDMI The TV is connected to the receiver via Optical Out -> Optical to Coaxial converter -> Coaxial in Why is my receiver only getting a PCM signal when Roku(Youtube) is playing a dolby digital video? Anyone with any ideas please? Quote Link to comment Share on other sites More sharing options...
WholeHomeControl Posted June 1, 2020 Share Posted June 1, 2020 Some TVs only support PCM through optical out when passing through an HDMI source. Another possibility is that your TV’s optical out is configured to send PCM in your TV’s audio settings. What model TV do you have? Quote Link to comment Share on other sites More sharing options...
brucecampbell Posted June 1, 2020 Author Share Posted June 1, 2020 Hi. Tv is Panasonic TH 55FX640I’ve been playing around with Netflix on Roku, Apple TV and the Panasonic TVLooks like I’m getting Dolby 5.1 with Netflix but not with YouTube. All three sources provide sound to the receiver via the tv optical out. Trying to research YouTube and found some info saying YouTube supports 5.1 but recorded it to 2.0. Not sure why there are so many Dolby test videos on there?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
brucecampbell Posted June 1, 2020 Author Share Posted June 1, 2020 I’m watching The Matrix scenes on Netflix now to prove 5.1 is working Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
WholeHomeControl Posted June 1, 2020 Share Posted June 1, 2020 Sorry, I reread your first post and see that clearly your optical is carrying Dolby. I've had trouble getting Dolby from YouTube on my setup as well (Apple TV direct to receiver.) Let me recheck exactly what I get from YouTube.

brucecampbell Posted June 1, 2020 Author Share Posted June 1, 2020 I just assumed YouTube videos demoing 5.1 and 7.1 etc were in this format. Everything I’m reading online now is saying YouTube used to offer this sound feature but no longer does.

WholeHomeControl Posted June 1, 2020 Share Posted June 1, 2020 Yup, I get nothing but 2 channel from YouTube via Apple TV. Quote Link to comment Share on other sites More sharing options...
brucecampbell Posted June 1, 2020 Author Share Posted June 1, 2020 Thanks for confirming. I’m now finding some movies on Netflix are not in Dolby digital either. I always assumed it was pretty standard since the 90’s. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
