I noticed there were a couple of places where I impiled MYFLT => float, so
I fixed this in CVS now. However, that might not have been the problem.

Thank's for your so fast reply !

No luck, it stops at the same points. But a new thing : i no longer get the
"Solaris buffer underflow!" with trapped.csd.

- maybe also my issue isn't strictly rtpulse.c related...

Cheers,

Sergio
