This question seems dumb but Ive searched a lot and haven't found a straight and applicable answer yet, so im asking here. I'm planning my first rack, which will be portable. I have everything I need for output at home, but constantly lugging around a clunky audio interface is a hassle and kind of defeafs the purpose of the rack being portable. Basically I'm wondering what people use for audio output when not at home, or potentially outside, which is something I hope to do at some point.

Knowing me I'm probably overthinking and missing something very obvious, but I'd appreciate any help.
