I have a fresh install of Wheezy on a DELL latitude 6530 with LXDE, Iceweasel + Flash plugin and some more apps. Sound worked just fine, however, it has just mysteriously stopped working. I have worked with alsamixergui (and seen to it that speakers and master are on) and run
and... nothing :-(.
It used to work and I am lost... where to begin my search for the problem?
