I feel like there’s a very large number of people that are afraid of trying things on their computer just to see what happens. And it correlates pretty closely with the type of person that doesn’t know where anything is on their computer.
OP is at least asking questions, and that’s a great step towards learning by yourself.
Eeh, they’ve got a point though. This is the result of accidentally cating an image in TTY:
Fixable with a reboot. Shouldn’t cause issues with any normal text editor, but because it shouldn’t doesn’t mean it necessarily won’t.
Now cat a plain text file to your sound device as it exists in /dev (e.g., /dev/audio). Then do an audio file. You should hear stuff come out of your speakers.
PS. When your terminal looks like that, you should be able to type reset and press enter to fix it without a reboot.
