HELIX engine on 10.1

Hi, Using AMAROK, configured to use the HELIX sound engine in AMAROK configuration. I experiance short, sub-second, pauses in the playback. This happens regardless of source type: MP3 or OGG. Anyone else have this prob? Any suggestions as to how to fix it. I know that as purchased 10.1 and AMAROK cannot play MP3s ehrn the XINE engine is configured, but right now YAST is rejecting PACKMAN as an alternate install source. Thanks ......... PeterB
