Hi there have a Samsung tv and just bought ehw450 have connected per instructions and no sound , tried aux and hdmi but checked with usd and iPod and fine
You may want to review posts in the main HW-E450 thread. If you don't find the answer there, post what you have connected, where it is connected, and how it is connected. You haven't provided enough information for us to help you. Also post the model # of your TV. Does it have ARC?
