I think "my audio interface is a 64-bit Linux computer" would've sounded far more interesting to me as a title. Perhaps a decade or two ago, the functionality of that device would've likely been implemented on a small 16-bit or 32-bit SoC running an RTOS like VxWorks.
Given how many physical controls it has, turning it into a game console seems like a logical next step.
And your video dongle might be a Unix computer: https://www.macrumors.com/2025/02/04/doom-apple-lightning-hd...
My audio interface is a Linux computer with FPGAs inside (that actually get field-programmed), with two gigabit Ethernet jacks that each talk to different parts of the machine.
But I don't think anyone here would care about that. It's not such an unusual arrangement. I guess it's kind of impressive to use it on my desk at home, but in pro audio world it's actually kind of mundane.
Maybe I'll write about it more after I get the gumption to gain a root shell on it (or brick it, whichever comes first). I think you guys might find that part more interesting. :)
