I'm using the Elisa package from the opensuse tumbleweed official repo. All music is detected in my Music folder, and I can load it into the playlist, but it provides no option for playblack. The little playback button on each track in the playlist is grayed out.
I figured out the issue: some gstreamer codec must not have been installed, though I'm not sure which. I installed a bunch that do not come installed by default with tumbleweed (which causes several headaches). Playback works like a charm now.
