No sound when playing .RM video files

[barney_1]

Hi Folks,

I've been trying for a couple weeks to get this problem fixed but no dice. So, here it goes:

Kubuntu 7.04 Feisty (development)
Kaffeine media player 0.8.3

I can play .RM (realvideo) files and see video perfectly but I have no sound. I have tried installing the w32codecs, the xine-extracodecs, and several others.

When I run kaffeine with this command:

kaffeine --verbose

I get this error when trying to play a .RM file:

xine: found demuxer plugin: RealMedia file demux plugin

Any thoughts on how to correct this?
