cncb 17 Posted July 12, 2022 Share Posted July 12, 2022 I just got a Fire TV Stick 4K Max and in trying it out with the Emby app, I am not getting DTS-HD passthrough to my AVR. The stick is connected directly to my AVR via HDMI and I have DTS-HD passthrough checked in the Emby settings but it always outputs just the plain DTS core.

cncb 17 Posted July 13, 2022 Author Share Posted July 13, 2022 Strange. I guess the Stick is somehow modifying it before final output? Link to comment Share on other sites More sharing options...
ebr 14925 Posted July 13, 2022 Share Posted July 13, 2022 Or the receiver or connection can only accept the core DTS. Link to comment Share on other sites More sharing options...
cncb 17 Posted July 13, 2022 Author Share Posted July 13, 2022 (edited) I swapped it in for my Shield TV on the same HDMI connection so it certainly can handle DTS-HD (no problems with the Shield TV). Edited July 13, 2022 by cncb Link to comment Share on other sites More sharing options...
horstepipe 356 Posted July 14, 2022 Share Posted July 14, 2022 (edited) Hey sorry I do not want to hijack this thread, just some short questions: - The Amazon Fire TV Stick 4K (Max) is generally able to output DTS HD and True HD? - Can it do passthrough as well as lcpm output? - What about 7.1 DTS HD and True HD tracks?

Actually, no, it doesn't which is why it isn't happening in this case. There isn't much incentive for Amazon to pay a license for that since no streaming content provider delivers content with DTS-HD. Link to comment Share on other sites More sharing options...
cncb 17 Posted July 14, 2022 Author Share Posted July 14, 2022 It seems that it only supports passthrough of DTS-HD HR and not DTS-HD MA. This probably won't be a deal-breaker for me since I only have a 5.1-channel system now. It is strange how they convert everything else to DD+ on the fly. Seems like it would be taxing on the device. I have never understood why they would need a "license" just to pass the signal untouched to an AVR? Another issue is that it turns out I have several files with VC-1 encoded video and unfortunately the Stick does not have hardware-decoding for those.

In fact, there is no mention of DTS support either but I'm pretty sure it won't support TrueHD. Link to comment Share on other sites More sharing options...
cncb 17 Posted July 15, 2022 Author Share Posted July 15, 2022 It converts everything that is not DTS (including TrueHD) to DD+. I still don't understand how it can do this so efficiently. Link to comment Share on other sites More sharing options...
