Hi @jehoho and welcome to Backstage! 
That doesn’t sound very good (sorry for the unintentional pun).
Things you could try:
- re-flashing the latest firmware
- create a new project and place some samples on a track
- see if you get any output this way.
If that doesn’t help, get in contact with support and they will help you from there.
Hope you can get it resolved quickly
