+  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.
