Summary: Real-time ending too soon?
Initial Comment:
When running the joined csd file in real-time (csound rttest.csd), I get an audible click in the end of performance. If it is performed to a file (csound -W -o rttest.wav rttest.csd), there's no click in the end of the generated audio file. Same result using the API. It seams that the real-time run of csoundPerform misses some cycles in the end of the performance.

I've rebuilt csound from latest cvs (Nov 29 2010) on my linux box (ubuntu
10.04 LTS). The bug is still there with alsa. I cannot try with portaudio,
because now csound tells me:
*** error: unknown rtaudio module: 'PortAudio'
Failed to initialise real time audio output
Actually I get aroung the bug by adding 'e 2.5' to the end of the score
section of the file 'rttest.csd'

Message:
I tried with both portaudio and alsa and the bug was there. My csound was
built from cvs (July 29 2010). I tried too on a Windows box with the last
binaries from Michael and the bug was not there. So, I will rebuild csound
on linux from recent cvs and have a try. I'll let you know what happens.

I assume this is with Portaudio. Can you confirm that t happens with ALSA
as well?
Just trying to narrow the search
