er .. just to confirm, can you play any other audio file using any other
I use audacity a lot and it works fine on Ubuntu. The only things I have
to deal with are:
1. The appropriate output device should be selected. The device number
might change on reboots if you have multiple output devices.
2. The volume of the output device should be non-zero. On a command
terminal, type alsamixer and press enter. The GUI shows the volumes of
all devices. Press left/right arrow keys to move between devices,
up/down keys to adjust volume, and ESC to quit that GUI.
