Il try to give as much detail as i can.
when playing eve i normally use either vent' or listen to some music via winamp or VLC, Each time that I session change (dock, undock, use stargate) i loose sound entirely. However, if i close vent' or click stop/play sound returns untill i next session change.
This is where it becomes entertaining, i use a razer-megalodon
the cool thing about the device (and also its bane) is that it is a all in one device, it plugs into any usb port and runs its own sound processing meaning no sound card is required, i've updated the firmware for the headphones to the latest.
Normally i wouldn't think Eve could be related to something like this but as the issue only ever occurs during a session change leads me to think that it has some part to play.
