On my previous installation of ubuntu 10.04 it was possible to set a sink in pavucontrol, which is affected by the volume up-/down buttons on my keyboard. Now in Lubuntu 11.10 this does not work anymore. I can check the green tick, but this affects nothing, still always one and the same sink is affected.
Did anybody have this before? Where is this function configured - is there a config file, in which I could change this configuration directly?
