I am a long time user of Ubuntu and using banshee and/or rhythmbox for listening to internet radio.
Since my upgrade to 13.04, neither banshee nor rhythmbox are able to play internet radio as a normal user. Banshee with status "idle", rhythmbox with status "paused".
Logging in as root, however, there's no problem.
Could it be a permission problem for a device? A socket perhaps? I can't identify a device or socket however, using
looking in /proc/PID/fd.
