This tells me that the receiver is properly receiving a DD signal and is using it as is. When I watch Netflix through my Samsung smart tv’s embedded app, my receiver automatically says Dolby Digital without even me having to select any audio mode. But again, no sound except from front speakers. So I chose multi-channel in and the receiver shows that indeed the input is 5.1 and that the output is 5.1. Additionally, on my receiver I can choose the type of input (stereo, multi-channel in, direct, etc).

So apparently this means things should be working okay, right? The problem is that when I actually go and watch Disney+, I only hear sound out of the front speakers (not center or rear speakers). I finally got a chance to look into this and I can run speaker tests that clearly output sound to all 5 speakers (and sub). Yes, I already know that over HDMI the Realtek controlled audio doesn’t factor into this. it should show “Dolby Digital” on the display).Īny ideas here? I have also already tried updating both the display and audio (Realtek) drovers. I should note that also when a true DD signal is input my receiver it shows on the front panel the signal type (e.g. The one time I got it to work I didn’t even have to select 5.1 output to get it to be output over my speakers. I could’ve sworn I got it to work one time and the audio quality was great (and loud :)). To be certain, I am viewing Disney+ material using Microsoft Edge (which supports full hdmi/audio/4K features, unlike Chrome). However, I noticed that when I select 5.1 or 7.1, the audio is quite muffled and low quality. It does properly show that my connected device is my Denon receiver. When looking at my laptop’s (XPS 13 9370) audio control icon, it shows that I can select among a number of options including stereo, 5.1, 7.1. I am trying to get true 5.1 audio output over HDMI connected to my Denon AVR-4000 receiver. I’ve been struggling with this for some time now.
