Samsung Soundbar HW-C451 - Buzzing with Xbox 360 optical


Standard Member
Model: HW-C451
Connection type : optical

I purchased the HW-C451 a few days ago, and have loved it so far. I have 3 devices I swap between the 2 optical inputs. (Mac Mini, PS3, Xbox 360). The PS3 and Mac work without problems. However, The second I turn on the Xbox 360, I can hear a humming noise coming from the soundbar (both speakers). This is not present with any other device.

I have tried 2 different Xboxs (Elite, regular), also swapped the optical cable for a known good cable, also swapped the VGA video cable on the Xbox. (we have 3 in the household). I have also unplugged all other devices in the room, including the wireless sub, to minimize interference. The problem persists.

The only other thing I can think of is the wireless router in the house. I have disconnected the wireless on the xbox, but have not yet changed the frequency settings on the router.

Any thoughts? Help would be greatly appreciated.

slighlty off topic, but can I ask where you got the 451 from?(silver version) as I have been looking everywhere and only ever see the 450 black soundbar. Thanks
