Low sound output Mandrake 10
I have just installed Mandrake 10. Everything is fine except for the very low sound output when using Totem and Realplayer (I downloaded the Realplayer 8 RPM). There is nothing wrong with the speakers or sound card - the system plays CD's at full volume, and Totem plays DVDs fine as well, but when I try streaming audio from, say, the BBC, the sound is there, but incredibly low. At first the streams were opening in Totem, but I changed the helper application in Mozilla to Realplayer, and they now open in Realplayer, but at the same very low sound.
I can't find a volume control in KDE, but I've been using Gnome as well, with its volume control set at max.
Can anyone help?
