Hi, Yes i get that strange sound too, it happens with both the optical and analog inputs. It's different depending on what I'm listening to. During a led zepelin Blu Ray Dolby disc i have it sounds like a reverb is added to the back speakers. But on my Chicago Blue Ray (NO Dolby used during their recording only DTS) the back speakers sound fantastic. Some other music sources do exhibit a wierd mish-mosh of delay or mis timed chanels. If I dont like the way that sounds, i just turn off the first blue light, turn on tru volume and crank it up. I've dont have a PS3.
ANY WORD ON THE VOLUME LED'S ?
Mine worked flawlessly for 5 weeks, then two days ago I thought it wasn't working, I got up real close to the soundbar and I could see the LED's were working, but so FAINT that I couldn't see them more than 2 feet away. I unplugged the power cord and held the power button in for 30 seconds and the lights are back to normal. Can't Vizio come up with some repair or replacement for this. I think they owe us owners an explanation. I guess I'll just return it before my 90 days is up at Walmart. Without the LED's I cannot get it adjusted properly. Any other ideas? Bill
PS. Concerning the Optical, direct from bluray or set top box, verses Optical thru the TV's HDMI versus analog, ...... they all sound the same to me, so don't waste your time with the opitical switch and a bunch of opitical wires all over the place. Just put all the devices thru the TV ( I have a Vizio E550VL) with HDMI's, then from the TV to the soundbar using the Optical input. Additionally I hooked up a red/white analog cable directly from the Bluray to the soundbar using input #1 (labeled "IN" on the remote). I can play MUSIC from the bluray to the soundbar with the TV off using the analog cable. The Bluray is also plugged into the TV with an HDMI cable for playing movies and other video, for this I use input # 2 (labeled "OPITICAL" on the remote).
