![]() So, RMP will in fact "output" audio encodes other than PCM 2.0 - assuming the "input" is AC3/EAC3/DTS, even with sources that have multiple "HD" audio tracks ahead of the AC3/EAC3/DTS track I am happy to help diagnose further let me know what to do.įor your setup, the stream has to be encoded in DD (AC3) in order for it to be passed, and since nearly every major streaming service is now streaming in DD+ (EAC3), you of course wont be getting a DD (AC3) signal passed unless you can find a streaming service/channel that does so (good luck, though it sure would be nice if they all did as a fallback since they already have multiple encodes, but I digress).Īs far as RMP goes, it does in fact correctly pass DTS and AC3/EAC3 however, it does not pass through the "HD" audio codecs (DTHD, DTS-MA/HD, etc). Maybe that is what is happening with my Roku Stick? I see there is another thread about this issue for the Ultra 4640 where it was determined to be a firmware problem. But it never switches for the Roku thus it seems the Roku is not sending surround audio at all. So I know it works correctly when it gets Dolby Digital. The receiver normally switches to Dolby Digital mode when 5.1 content is sent to the TV via an HDMI input, such as from my Blu-Ray player or my Dish receiver/DVR. It is connected to the TV via optical SPDIF cable the receiver does not have HDMI ports. Receiver = Denon AVR-1601 from circa 2000.It is configured correctly for RAW audio pass-through via optical SPDIF to my audio receiver. Roku Stick is plugged directly into the TV's HDMI and USB ports.Settings > Audio > HDMI is Dolby D, or I can set it to Auto and it correctly detects Dolby D, but makes no difference. ![]() ![]() Other formats like AAC 5.1, AC-3 of any type, MP2, and PCM all yield silence. When playing content via the Roku Media Player channel, sound is only heard when the video has a mono or stereo audio stream in AAC or MP3 format.Tested content includes 5.1 material on Netflix, Amazon Prime, HBOGo, and Roku Media Player channels. For all content played on the Roku, my AVR remains in stereo mode and does not detect Dolby Digital 5.1.I'm getting the classic scripted runaround from the front lines of Roku Support, so am trying here. ![]()
