After installing all the required libraries (libnjb, etc), amarok would not recognise my Creative Zen Sleek MP3 player.

Gnomad2 would connect to it, but only if started with “sudo gnomad2″.

But, I found the issue – user privileges. Here’s how I got it working:

• System / Administration / Users and Groups
• Unlock if necessary
• Select user
• Properties / User Privileges
• Check the “Use audio devices” box.  For some reason, this is unchecked by default

Amarok now connects, and gnomad does not need sudo, though I don’t need to use gnomad any more.
