Sound goes into a loop when you change channels on the TV. The only way to stop it is to shut everything down and restart.

Works some of the time. Often when I change channels, it goes into this LOUD static sound, then I have to change settings or power off then on. Sometimes the visual doesn't match up with the audio, and I have to turn it off and then on to set correctly. I wouldn't have bought it if I had known.

the switch is cheap. i have to use contact cleaner to get it to stop making noise on every show.  it works once you get the noise to stop. :-/

I purchased 2 of these on sale a year back.

On BOTH the subwoofers lose connection with the bar, the sound comes out intermittently but frequently, making the whole sound experience terrible. The subwoofers were properly installed and on clear view of the sound bar, and still it just won't work right. Also, we are big Vizio fans, we love our TV, too bad this sound bar doesn't match its quality.

Not really impressed. Very annoying if you have a TV that will change to a newly detected source. This thing goes up and down all day, and you will find yourself reach for the remote to change the TV back to the source you were watching before switched.

When it is working, it works well. However, when I turn off my headphones it goes into standby and won't re-connect when I turn the headphones back on.

I connected it o the Audio Out AND a USB port (for power)  in back of the TV. The instructions say  that you can use it while it i charging, so my hope was that I could just hook it up this way and forget it. Wrong - I've had to reconnect every morning.

The problem turned out to be that the transmitter powers itself off overnight when the TV is turned off and the USB port loses power (maybe after the battery is drained also). When I plug the transmitter into a USB port that remains powered overnight, it works as I expected.

I raised my rating from 1 to 4 stars. The only reason I didn't give it 5 is that there will be a visible wire running from a live outlet to the back of the TV - either a USB power cable or an audio cord, depending on where I put the transmitter.

Works great with HD channels.  Unfortunately, when used with non-HD channels, every time I adjust the volume, the picture goes black for several seconds.  Always comes back on, and sound stays on during the "black-out".  Otherwise, performs as advertized, and sound good.  I am using it with a bose system (non-powered subwoofer and 3 satellites -R, L, and center).

Gets a really clear picture but sometimes has to be moved around after changing channels (similar to the old rabbit ears)

The sound is good for the price, but it randomly turns off by itself. This has happened with two separate units...but hasn't happened for some time now on the current unit. When it works it's great. The unit turning off may have been an isolated incident as I haven't read other reviews.

UPDATE 4/22/12: Unfortunately it is turning off by itself again.  Simply unplugging it and plugging it back into the power will bring back the sound (like setting it up for the first time), but it's annoying to have to do that when in the middle of a great action scene.  Tends to happen during loud scenes as if it can't handle the amount of sounds and just turns off.  I'm using it with the Sharp 80" LCD/LED TV so maybe they just don't play well together.

When I connected my PC to my HDTV with this cable I could hear a clicking sound coming out of my TV speakers in one-second intervals. When I use the separate audio cable the "clicking" was gone. My guess is that the audio wires inside this cable are not shielded and VGA video signal is interfering with PC audio signal

Ok so far, only thing I've been able to do is turn the tv on/off. I haven't been able to turn the volume up/down or change channels. Will update if there's any change. Not sure if it's worth the 90$ buy if it can only turn your tv on and off.

Worked OK for about 2 weeks. It was confusing to try to figure out how to get it to work with my TV. Finally figured it out. When I go to bed I turn on my TV(sound all the way down) and listen to the TV thru the surround sound. When the tv turns off the surround sound stays on but last night the buzzing actually woke me up. I turned it off and you could hear commercials playing. I had to turn it off with the switch on the back of the unit. Do not think that was supposed to happen

Whenever I try to play a game, the speakers give off a weird buzzing feedback sound, enough to the point where I have to unplug them.
