From csound:

*** rtjack: sample rate 44100 does not match JACK sample rate 44099

Then quits.  I started jack with qjackctl, and left everything
default.  The sample rate there is chosen from a pulldown and
is set to 44100.  I change the csound orchestra to use sr=44099
and then the orchestra runs (I didn't get any sound yet, but
I'll have to track that down).

Anyone have any insight?  Maybe a floating point rounding error?

toby@vsinewave:~/music/csound/two$ csound
0dBFS level = 32768.0
Csound version 5.12 (double samples) Nov 20 2011
libsndfile-1.0.21
...

Thanks,

Tobiah

I'm running csound on Kubuntu in a Vmware machine on Windows 7.  The
card appears to the VM as an Ensoniq AudioPCI, but the hardware is an
Echo MIA Midi.  I suppose the problem could be in there somewhere.

this is a sound card / driver bug, I have the same issue with one of my cards and the ardour devs explained the problem (jack started as an ardour side project). one workaround is to switch to 48000 as an sr, I guess the bug is caused by cheap cards that have problems supporting both sample rates properly. If jack reported a 44099 sr as 44100 this could cause client synchronization issues, and they are sticklers about sample per sample accuracy.

My buggy card is an Ensoniq AudioPCI. Perhaps since you are having the problem it is the driver that is buggy?
