I compiled Audacity ® 2.0.0 (Unicode) from source, the executable runs successfully from the build directory, but there is no sound output.
In the “help->audio device info” there are no devices listed,
Default capture device number: -1 Default playback device number: -1 No devices found
In “preferences/devices” there is no content in the dropdowns (i.e. no host, playbackdevice)
“transport->scan audio devices” does nothing apparent
The 1.3.13-beta version installed from Ubuntu repository does produce sound and does have many devices listed.
