Affects: rhythmbox (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
in Breezy up and down controlled the volume in rhythmbox, letting me
trivially adjust volume as needed. Now up down seem to be confused with
forward and back for positioning the song.
