Lost system notifications

[Alan Chandler <alan@chandlerfamily.org.uk>]

Last week sometime, I rebooted linux 2.4 (from 2.6).  As a result sound was 
not installed (because 2.6 uses alsa).

I logged into my kde account and obviously something there detected that there 
was no sound server because sound for the system notifications has stopped.  
Playing with control centre does not get it back - although testing sound 
within the "sound system" page of the control centre does actually play 
something.

I can log into root and kde plays the system startup notification there just 
fine.

I presume there is something in ./kde/share/config that I need to tweak.  Can 
someone point me at what.

Thanks
