[Problem]: Complete crash while streaming due to output_device_error_19 #2058
Description
What happened?
This happens both when running as a service, or manually running in userspace (though anecdotally, I feel like I've had better luck in having less time between crashes when manually running?). I have seen a few issues that report the same output_device_error_19 error, but they don't seem to be related to a crash during normal functionality.
What happens:
- Start shairport-sync
