it works!!!!!!
why???? Should not be limited by the sound card?

It report a warning:
>>> Warning: This flow graph contains a throttle block and another rate
limiting block, e.g. a hardware source or sink. This is usually
undesired. Consider removing the throttle block.

but it keeps the CPU under 40% and works fine.
Even with samples/symbol set to 8 it has go to 95% CPU but it has worked
some seconds until it has begun to show aUaU.
