Audio does not ever play on specific instance

[virtueisdead]

I figure that, in the pipeline from my server to my screen, this has to be an issue with the way my piped instance (or possibly my reverse proxy) is configured, but neither libretube nor the piped web application have this issue, so I'm not really sure where else I ought to go to ask this.

Using my instance (API is https://pipedapi.virtueisdead.xyz/) I have tested several videos on three devices (Raspberry Pi 3+, fire stick, and debian laptop) and found this error happens with all of them. For demonstration I used this video: https://piped.virtueisdead.xyz/watch?v=ChO586cR3hQ

I tried the same video, as well as others on https://piped.nosebs.ru which worked perfectly fine

However, on piped.virtueisdead.xyz, the video will play perfectly fine at any quality, subtitles will work fine and be synced correctly, but the audio stream shows up as "null" in the player and "unknown" in the audio stream selection, and there is no audio playback whatsoever.

Here is everything relevant in the log as far as I can tell, up until a few irrelevant lines and the start of application shutdown:

The only part that seems out of place to me is the very last line "CVideoPlayerAudio::Process - stream stalled", but I don't have the knowledge to tell if that is actually relevant or not.
