Please advise what is the correct soundbar (by part number) for a Dell P2222H monitor, and does it need any additional hardware other than what comes in the kit? I'm looking for a soundbar that would attach directly to the bottom of the monitor and not some rigged-up deal that attaches to the monitor stand by a clamp or some-such, primarily so the speaker will rotate along with the monitor when the screen is turned in a particular direction. Thanks, and standing by.
