My Surroundbar 360 has started making a high pitched humming sound when turned on. Does not matter which input I use (cable box, dvd, etc). It's so bad I can't use the system. Any suggestions on cause/solution?

    Are your sources set to output PCM? You can check in the menu of your cable box/dvd/etc.

    Otherwise, I would suggest contacting Polk Customer Service.

    I am having the exact same issue. Have had the unit for a little more than a year. Had it sent back two times for other issues that popped up. Contacted customer service via email this time and got no response. It is out of warranty now which is a bummer. Did you ever get this fixed? If so how?

    Thanks
