g'day there- ive been running cecilia  on my linux box
with great success, and now im moving towards a real time application of
cecilia (live dsp).

ive got a couple of questions relating to the Audio-in function.
I can write to the DACs no problem, but when i attempt to read audio from
the soundcard and write to the DACS, problems arise.
ie : i run this simple orc/sco (in csound alone)

/usr/Csound-3.47/ csound  -o /dev/audio1 -L stdin  -i /dev/audio0
rtinu.orc rtinu.sco 

I get a short looping buffer of ambient sound. The orc/sco compiles no
problem (and does work properlly on a mac). It may have somthing to do
with the command line. Here is the output:

Csound Version  v3.485.0b (Aug 27 1998)

new alloc for instr 31:


The other question relates to cecilia.
When i select preview command and/or opoen cecilia window, csound does not
compile (doesnt initiate compilation) and cecilia just hangs (until i
reinit module).
This in itself isnt such a big problem, but how does one change the
command line options (ie audio devices) without this previewer- (where is
the default file kept?)

I also (on occasion) get the following error message when atempting to
preview the command....

grab failed window not viewable

Any ideas would be appreciated....
