Can anyone throw any light on the crash below? It is
from a customer site and I am told it occurred while the user was reconfiguring
the inputs on his PreSonus Firebox. The only audio device property
listeners we install are for kAudioDevicePropertyDeviceIsAlive and
kAudioDeviceProcessorOverload so I don't think it's us. And we gracefully
handle, for example, unplugging a USB device, so I know that our listeners are
well-behaved.
The following appears in the list of loaded dylibs.
I don't know if it might be relevabnt:
0x43e000 - 0x44aff7 +com.rogueamoeba.audio_hijack_server.hermes
2.2.5 (2.2.5) <CD6C7A74-BA03-F3A7-0D1E-460E6A043024>
/usr/local/hermes/modules/Instant Hijack
Server.hermesmodule/Contents/MacOS/Instant Hijack Server
Other than that, the machine in question seems to be free
of potentially destabilising plugins. From other information in the crash
report (which is meaningful to me but not to anyone else) we were taking audio
from the Firebox and playing it back through the built-in speakers out at the
time.
Any input gratefully received.
Many thanks,
Paul Sanders
