I'm a grumpy old man, and no one can ever make me care about any audio transport fancier than analog stereo. To my dismay, it's getting hard to find TVs that can even provide usable stereo output without some kind of extra decoder box or something. Luckily, last time I bought a TV, I was still (barely) able to find one that had a headphone jack, which I use as a stereo line out.

What's it matter if the DAC is inside the TV or out, beyond the one in the TV is probably a cheap piece of crap. The important thing is the TV support plain Jane 2 channel PCM for digital output. From there you can go anywhere and do anything without loss or codec compatibility nightmares.

For me it's because there is no other dac. TV to mixer to monitor speakers via 1/4" TS.

Somewhat tangential, but here's a cool somewhat open-source project related to Dolby Atmos: https://cavern.sbence.hu/cavern/ https://github.com/VoidXH/Cavern The visualizer, which is what I was _most_ interested in (along with software decoding) is written in C# and the rendering is done in Unity -- both things I valued & thought were cool. In theory, you could build a DIY multi-channel "receiver" with this type of s…

I wonder if this could be adapted to spatially-tracked headphones, or even wasd+mouse

It's still TV to mixer to speakers in that case just the TVmixer portion is SPDIF digital instead of TRS analogue. I.e. the mixer is the DAC instead of the TV and the analog portion is limited to the actual connection to the speakers.

TV selection options go through the roof while analog loss and interference in the mixer is eliminated.

Next time I'm in the market, I'll consider this. I'll probably have to get a mixer then too, instead of using this half broken 30 year old one I have kicking around.

fwiw, you can get a higher quality output (if your tv has it) via optical and/or hdmi looking for the "PCM" output setting. on my recent tv (an LG) it was buried in the settings and greyed out until i turned off all the Ai processing bs. only then could my external stereo DAC work.

Is there a DAC that takes HDMI input? That's not big/expensive?
