I am a (prospective) brand-new user who would like to use SoundJack on a desktop Linux running Archlinux/Kde.
After solving some lib-dependencies issues, I was able to start SoundJack from the command line. However, when I click on the “Stage” tab in the SoundJack webpage, I get a load of Alsa errors in the terminal and the stage controls do not appear on the stage page at all:

Help greatly appreciated
Never mind, it seems those messages are alsa debugging info (even though the “unable to open slave” is rather worrying). I was able to open the Stage panel by switching browser from Firefox to Chrome.
