I know this isn't really Apple-related, but here goes ... I have the following set-up: - Philips 42" LED TV (42PFL4007H/12) - Harman Kardon Soundsticks II speaker set - Apple TV The speaker set has a standard 3.5mm jack, but my TV only accepts an optical audio connection ... Is there any way to convert the signal? If so, what should I buy? Thanks in advance P.S. I can't simply plug the speaker set into my TV's headphone port, because then I can't control the volume level.
