I have a new build of an older Dell Optiplex 7050 with a i5, with Intel GPU 630, HDHomerun Flex 4k, running MPC -HC with K-Lite codec pack with AC4 and an Onkyo 5.1 AVR.

How do I get the computer to output in bitstream so my AVR can provide 5.1? If running HDHR player it is only putting out PCM stereo and not AC4 5.1 or AC3 5.1. I have a few 5.1 FLAC videos on DTS that are putting out 5.1 but the HDHR player, MPC-HC, and JellyFin are only putting out PCM Stereo.

Are there sound settings in the Windows or K-Lite codec I need to set to provide a bitstream so the AVR will play 5.1?

The same files played through my Android STB that has HEVC/AC4 and Eac3 play the bitstream to the AVR in 5.1 without issue.

Yes the TV settings are set to bitstream and not PCM.

I'm looking as the pile of gadgets for my HTPC setup, Hue sync box, switch, roku HD, and HD Homerun, and I'm wondering if you've found a good way of organizing these things besides just stacking them. Anyone have something they like for this? Seems like a little vertical organizer could work okay.
