Follow-up Comment #8, bug #59547 (project denemo):
I was looking into a different problem and stumbled across what is most likely
the cause of the crash you reported.
I've fixed the code in the repository and would appreciate it if you can
confirm that the problem is fixed. To test you will need a clean start -
easiest is to remove any directory .denemo-* in your home directory.
rm -rf ~/.denemo-*
so as to remove the spurious entry in denemorc that will cause the crash.
The correct value to use for audio output is "default", which denemo was
substituting with the first device found. This was being done because at one
time the portaudio library was failing to work properly with pulseaudio and
only selecting a specific device would work. What the code didn't anticipate
was that the Alsa library would crash on being asked to use some particular
device.
The problem with portaudio and pulseaudio has apparently now been fixed and so
"default" should select the appropriate mixer to allow Denemo to output audio
mixed with any other program that is also using the audio output.
