Comment 6 for bug 160367

Thanks. That's very helpful: I had not tried testing it with the capture input muted (as this would clearly be an inappropriate setting for recording). On the other hand, when started in this configuration, audacity should either complain it cannot record, or record silence (the output of the muted element). Additionally, audacity should default to use the default ALSA input/output at initial startup, to reduce the chance that people may encounter this issue.
