Hi all,
We have a number of production CAs using a USB conference mic, but on a
newer i7 Dell machine, we're getting gstreamer errors like this:
2012-09-10 16:29:05 WARN [gstreamer service thread 1]
(GStreamerPipeline$3:154) - alsasrc0: Can't record audio fast enough
2012-09-10 16:29:05 WARN [gstreamer service thread 1]
(GStreamerPipeline$3:154) - flacenc0: The stream is in the wrong format.
The config is in all other ways identical:
# Create the audio capture
capture.device.Audio.codec=flacenc
capture.device.Audio.flavor=presenter/source
capture.device.Audio.outputfile=audio.flac
capture.device.Audio.src=hw:2,0
capture.device.Audio.type=ALSASRC
and the mic is definitely registered:

Any ideas? It's definitely not a "short on CPU" problem as these are
faster machines than older CAs on which it works fine.
