💖 AUINFO(1) 💖

okay so bestie, welcome to the General Commands Manual, and today's main character is auinfo — yes that's the title up top, that's the vibe, we're doing this 🫶

✨ NAME ✨

auinfo — the little tool that spills ALL the tea about a Network Audio System server 🎧👑

🌸 SYNOPSIS 🌸

auinfo [-audio servername]

🦋 DESCRIPTION 🦋

So like, auinfo is the program you run when you wanna know everything about a Network Audio System server. Not in a creepy way. In a respectful, thorough, investigative-journalist way 💅

It literally lists:

  • the capabilities of the server (what it can do, its whole resume)
  • the devices that are attached to it (the hardware besties)
  • the data formats that are accepted (the languages it speaks)
  • any predefined sounds that have been stored in the server (the pre-saved bangers 🎶)

it's giving "background check but make it audio" and honestly? iconic.

🔥 EXAMPLE 🔥

here's what auinfo spat out when it was connected to an NCD MCX(tm) display station. look at all this data. we ate. 🍽️✨

🎀 ENVIRONMENT 🎀

  • AUDIOSERVER — this variable is the one that says which audio server to hit up by default, but ONLY if -audio wasn't given on the command line. like, command line walks in first, AUDIOSERVER is the backup dancer 💃
  • DISPLAY — if AUDIOSERVER isn't set, then this variable gets examined instead, to find the name of the corresponding X Window System display. so it's a whole chain of "okay but if not them, then them" 🫶
