Thanks :)
I never used any sounds in my programs, and in jam there is no time for learning how to make and use them :). A while ago I was looking at sound libraries and YSE looked pretty promising, but I've never used it. Maybe next time :).
I use BFXr - http://www.bfxr.net/
I've heard good things about Musagi for music http://www.drpetter.se/project_musagi.html
I normally use Bosca Ceoil - https://terrycavanagh.itch.io/bosca-ceoil
Good luck! :D
