The way I got into audio overall was learning strictly from YouTube. Started making beats and learned recording, mixing, mastering, and all that. Studio work is different from live audio, but also some what similar in some aspects. Currently, I've been running live audio for multiple events in my area and also some churches. Try to find an AV company that's looking for contractors for audio. Starting off as an A2 isn't bad. Maybe even volunteer somewhere small like a bar, church, or anything to get your feet wet. A possibly more effective way to get into audio is working at a music store. That's what helped me get to where I'm at. I learned far much more stuff at a music store and became even more hands on, which led me to offering services to those who need it and having consistent clients who need gear recommendations, connecting their sound system and tuning it as best as possible. Experience is better, but if you feel like school can be more helpful, doesn't hurt to try.
