I have a serious problem with sound control in my ubuntu 13.10.
It just went crazy. But, to be specific - it's constantly making the volume go up to the max and now it's flashing in the upper right corner.
And it happened suddenly, I was listening to music and I easn't changing the volume. I restered my pc and tried to shut down some proceses but with no effect at all.
EDIT: Ok, so I restarted it once again, tried to change the volume from notification and it worked, when I used keyboard buttons it rapidly went up but now it works fine. Still, I don't know what seemed to be the problem but it's a bit worrying...
