     Type:  defect                          |      Status:  new       
 Priority:  minor                           |   Milestone:  unknown   
Component:  Plugin - MythMusic              |     Version:  0.22-fixes
 Severity:  medium                          |     Mlocked:  0         
--------------------------------------------+-------------------------------
 When I select CD-Audio as input source for Mythmusic I can stop/start
 playback
 Mythfrontend logfile produces:
  WriteAudio: buffer underrun

 MP3 playback ok and GNOME CD player works ok too
 Just seems to affect MythTV.
 I thought it might be related to my TV recording playback where I get same
 message.
