X-run = overrun or underrun. Sometimes the OS does a poor
job of keeping up with the timing constraints of the device
or application and misses a deadline. This doesn't have to
occur because your machine is not fast, but rather because
linux is a multi-user operating system and needs to be
coaxed into treating JACK and its clients as special, FIFO.

Running as root may not be ideal. You can minimise the
impact of this by enabling capabilities and use jackstart
instead as a normal user.
