I have installed OMV 3, no problem.
but now i wanted to backup a share with the usb backup plugin.
It does work, but, there is no beep when it starts/stops syncing.
i wasn't sure if th einternal speaker still worked, but when i took out the drives and ram, then booted, then i heard a stron beep from the internal speaker in the pc.
I really hope someone can push me in the right direction where to look for it.
