<p class="warning">
On Linux, the latency of USB audio interfaces is not constant. It may
change when the interface is reconnected, on reboot and even when xruns
occur. This is due the buffer handling in the Linux USB stack. As a
workaround, it is possible to recalibrate the latency at the start of each
session and each time an xrun occurs.
