thanks, yes this work nicely from the command line.
However, calling this from a small C-code looks not like a simple solution,at least one has to install ecasound,
on on quick search I couldn't find an API for it.

I also tried pysine, but I have difficulties to get it running.

To refine my question, I'm looking for a simple replacement usable within C.

Best regards,
Peter
