Somehow the speakers stopped working, and the headphone output added a loud hiss. Unfortunately, I was unable to fix it. + +My first thought was to reinstall the system, but then I remembered that I've read about [ZFS Snapshots](https://docs.oracle.com/cd/E19253-01/819-5461/gbcya/index.html). + +``` +zfs list -t snapshot +``` + +revealed that FreeBSD has already created a few of those recently.
