Volume control under KDE

[Roger Beever <roger2 rogernet net>]

Hi.
I don't seem to be able to find the volume control In KDE.
I can find various sound systems like aRTs where I can play test sound.
I can even start a CD playing and just about hear it  with the laptop
physical volume control right up.
The only vol control I have found is the Bell settings which is
available if I click the use sys bell box when tested it is very loud
until turned down to 1% and off at 0%.
Help please

Acer 508 laptop FC1 dual boot win98 sound  OK.
Same problem if booted straight into FC1 from switch on.
Regards Roger
