[Surround 3's crackling sounds]

I wonder if your TV audio setting could be the culprit. Check that your TV output is set to PCM.

[Klipsh Bar 48 with Surround 3 Speakers - 1 Speaker making a scratching noise occasionaly.]

Did anyone check to see what audio output your TV is set to? It must be PCM, nothing else. Can someone check and post please as I am interested in these speakers. Thanks.....

[Surround 3 clicking sound]

I just purchased a Cinema 600 Soundbar with Surround 3 rear speakers. There is an intermittent click or chirping sound from the Surround 3's. Sometime the left, sometimes the right. Sometimes every few minutes, sometimes not for and hour. How loud the noise is in relation to the volume.

I exchanged one complete setup for this and now this one is doing it. The only thing I notice is that the USB dongle that plugs into the right side of the Soundbar gets very warm.

Any thoughts or help would be greatly appreciated...

Thank you, John M.
