sound system not responding
I have installed a copy of backtrack linux on my computer and I have one problem about my sound system.
On the upper panel I have sound icon which show that currently my system is in mute mode(just speaker icon and no sound lines in front of it). when I click on it, a window pops up and shows volume bar so that I can increase or decrease the volume but when I set volume to any position a new dialogue box pops up and says "waiting sound system to respond" this wait never ends!! and that's why I am not able to listen any songs on my PC (I use banshee media player)
If you have solution to this please help me ASAP!!
