You were able to use digital optical out before because you indirectly paid for DD. They forgot the most important part of the fine print - it's optional and your motherboard didn't come with DD. Most people only see Realtek chip itself can do 5.1 or 7.1 and then assumes that you can play 5.1 or 7.1. The only way to carry 5.1 audio through optical out is by compressing the 5.1 audio using proprietary DD or DTS format. Optical out was designed by Sony and Phillips to carry 2 channels on uncompressed audio. Long story short, you didn't have DD or DTS because you didn't pay for it (in your computer and in your AV receiver respectively). Please refer to the screenshots of the properties window incase my explanation doesn’t make sense.Įdit: I cannot get the site to attach a second screenshot but the Realtek control panel does not help at all as it has less options than Windows properties does.

The motherboard is an Asus Z87 PRO w/ Realtek integrated, Win 10 version 1909, I could not find the exact model number of the sound card.
Why is the test the only place I can get audio to play on 5.1 and why does DTS Interactive play nothing? I want to note that through all of this Windows is attempting to play the audio (I think) as it shows audio playing on the mixer. This is the only time I can hear all the channels, even if it is selected on 2 channel under Advanced.Ĭlearly it is outputting audio to those channels despite it being on the 2 channel option. If I play the test Dolby Digital under Supported Formats on 2 channel 48000Hz or 5.1 DTS Interactive (5.1 Surround), I hear 5.1. On supported formats, DTS Audio does not output any audio, not even when I select the DTS Interactive (5.1 Surround) the only the one that does is Dolby Digital. If I use the 44000 Hz or 48000 option on 2 channels I get audio. Can’t get any audio on Realtek Digital Output (Optical) if I select DTS Interactive (5.1 Surround), the only option which is 5.1 in my settings.
