rat trouble with etch

["Mark Calleja" <m_c_001@hotmail.com>]

Hi,

I'm running etch with a 2.6.11-1-686 kernel and have installed the rat 
package, but when I try to connect to a multicast audio session I just get:

Setting volume: Invalid argument
Getting volume: Invalid argument
rat-media: auddev.c:957: audio_get_ogain: Assertion `volume <= 100' failed.

without the GUI even appearing. I'm using KDE as my desktop, and otherwise 
sound works well (mp3's, streaming audio, etc.) and have duplex sound 
enabled via the control centre.

Has anyone else experienced this problem? Can anyone recommend a fix?

Ta,
mark
