I installed Banshee player on my old Lenovo G430 running Lubuntu 15.04 (Vivid). It was able to scan through my music library and add all files to the library. However, when I try playing something, it goes through all the motions: the play time progresses, and the seek bar moves.. but it does not output any audio.
Audio and video play back fine in other applications, it's just Banshee that doesn't output anything. I couldn't see any options in the preferences to choose an output device, so I assume it plays back to the default output. How can I fix this problem?
