Been daily driving wireless Bluetooth earbuds on PC for more than half a year now, and as they're often turned off or in the charging case, it's always fun to see just how many games, including recent releases, are incapable of automatically handling a situation where there's no audio device in the system and refuse to launch in the first place, instantly close after loading or crash with a made up error, usually blaming something on the graphical side instead of the actual reason. Extra points if the game is able to run properly if you explicitly provide a -nosound or something similar as an argument but would refuse to launch otherwise.
in this vein, i use USB headphones that shut off if i take them off and fold them up when i leave my computer for a minute, and a ton of games (and plenty of other software with sound, frankly) will not handle the sound output forcibly changing gracefully, and will usually either stop having sound until you restart them or just crash. (Minecraft used to be an especially bad offender for me before more recent versions fixed this. it was particularly painful because of the long play sessions and ridiculously long load times with big Forge modpacks.)
i believe this is rarely anticipated because most people are just using the audio plugs on their PC, and that output device never disappears because the sound card doesn’t leave the PC when you unplug a 3.5 mm jack. incidentally, “audio device hotplug support” is the field i most want added to PCGamingWiki.
