By experimenting with interactive mode I have discovered what is causing the
problem.
I start in interactive mode and delete the default chainsetup.
I then add my own chainsetup, add 1 chain with a wav file as input and
/dev/dsp as output then start. All is ok so far.
Now if i disconnect and remove the chainsetup, then add a new one, again
with 1 chain, a wav for input and /dev/dsp for output. This time I get a
nasty buzzing in the right speaker as it plays.
Could it be that I'm nit allowed to delete and add chainsetups in this way
in interactivemode and eci or am I doing something wrong?
I have pasted a transcript of the interactive session below.

Tony
