Lifestyle 650 - sound dropping in and out
We have a Lifestyle 650 system purchased in April 2017. Worked perfectly well until approximately 4 months ago when suddenly the sound will drop in and out. You can hear it glitching and then occasionally it will drop out and sound like it’s underwater. You can still hear some sound but it’s muffled and very faint. Then it will work again. Totally random. Could go hours of use without an issue and other times it will begin happening within minutes of being turned on. Tried software updates, unplugging, resetting and none have completely resolved the issue. Always comes back. For a $7,000 system I would have expected excellent long term performance and we can’t afford to replace as speakers all hardwired in to media room. Please help us fix this problem! Thanks.
