No volume and usb

[limechallenger]

So, I hoped in my 2020 Rebel with 12 inch screen today to find that my usb stick (with all my music) showed no information! So I switched to FM radio and it has no volume! Everything else on the 12 inch seems to be working, just the audio functions seem to be out! Any ideas or past experiences?

Update!!! Hoped in the truck after work and everything is back to normal! Must have a gremlin!
