[LAD] Timing of the ALSA loop device

[Fons Adriaensen]

Hello,

Does anyone know what sort of timer is used by the ALSA
loop device, and if this can be changed in some way ?

On the system I'm working on now,  wakeup times while waiting
for a period to be available (as done by Jack and zita-alsa-pcmi)
seem to be quantised in steps of 3.3ms or so. Which means it
sometimes wakes up 3/4 or more of a period too late. Next one
will be xrun in that case.

Ciao,
