Hi,
The messages of the kind:
vortex: 0 virt=2, real=2, delta=2
vortex: 0 virt=11, real=3, delta=2
appear when your system is lossing interrupts because of overload. You are
asking your computer to do something it is not capable of. Thats it.
period size is measured in frames and period_bytes in bytes. AFAIK any
size is meant to be in frames.
Best Regards
Manuel Jander

Is it possible for au8830 to support surround51 by panning the center to
front speakers and bass to 4 speakers ?

AU8830.pcm.surround51.0 {
