Thanks this fixed my problem although i must say the sound volume is extremely low but never the less i have some sound
Make sure to check all the mixers: Kmix, Pulse audio volume control and the volume control in the
flash app itself, all of them add up to make the volume. You may need to activate channels in
kmix that aren't even visible (run Kmix, pick "Settings" Menu and from that "Configure Channels"
and experiment with the channels. It's possible an important channel is not showing and has
a low value. What you could try is unhide them all,
experiment with each one. Hide the control channels that your hardware doesn't use as you
try each one. This will make later usage of kmix easier.
If you use Gnome there should be a similar mixer to KDE's, I don't use gnome so I'm not sure what this would be
