Probably best to just run "sudo cyclictest" as it will enable
the /dev/cpu_dma_latency trick, if you run it will all the parameters
it will also use up execution time at a higher priority than your
audio, thus increasing the likelyhood of xruns. The full command line
is more to ascertain that kernel scheduling is working well.
