Help please!

Hey I know this is gonna sound dumb but I prefer to get advice from real people rather than google stuff (also I googled and it made no sense so this is the next option.)



I'm playing Pixelmon. Everything works fine... except audio. Idk how to fix it. Everything is up everything is on, but the game is muted...? Idk how to get sound and its driving my anxiety through the roof cause I can't have silence... so... anyone know how to make Pixelmon.. speak?
