it depends on the sw params you set up (if any). i think the default
is to stop whenever an xrun of any length occurs. i generally set the
stop threshold to ~0U, which means that the driver will keep the
interface running more or less no matter what - my app notes the
-EPIPE return codes and takes its own steps to
stop+reinitialize+restart when it wants to. what behaviour you want
will depend on your application.

Hi,

Am reading audio using snd_pcm_readi() and using short buffer times
that result in "Broken pipe" errors being returned. Occasionally losing
audio is not a problem, but do I have to completely reinitialise whenever
this occurs?

Tony
