+<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.
