i bought the u2412m soundbar and have the AY511 soundbar. The monitor has a connection for power for a soundbar but where do i get the cable to use this connection? any help would be amazing
The AY511 uses a Power Brick to supply power - it has a DC jack plug connector to fit the jack socket on the Soundbar. Your monitor also has a jack socket, used for the AX510 Soundbar. So you would need a short lead with jack plug on each end to connect your monitor to your Soundbar.
Wish I could help. I too am dealing with a sound problem. Mine is an inability to find how I can plug in my midi keyboard to the SoundBlaster. There doesn't seem to be an exterior plug-in for it on my Dimension E520. I know Sound Blaster was installed, but am vexed at the very real lack of a way to get the keyboard connected to the PCs sound system.
