I have made one change: using using `-i:alsahw,0' instead
of '-i:jack_alsa' and it is getting data. First indications
(1 hour of data) is that there have not been dropouts.
However, I can ask for -t:9900 but not -t:10000 for
recording times. With times above 10^4, in this
configuration, ecasound quits with:
(audioio_alsa) Using interleaved stream format.
ERROR: Connecting chainsetup failed: "Enabling chainsetup: AUDIOIO-ALSA: Audio
... format not supported."
I was not able to see how the recording time could cause
this error. The output format is .raw, and has not changed.
With jack transport, recording times up to 86000 seconds
were used. Is this limit a bug, confusion on my part, or an
undocumented feature (ecasound v2.4.6cvs)?
thanks,
