Recently started having an issue with my Klipsch Soundbar. Would like some advise as it is just over a year old and thus out of warranty. On both TV audio feed and Bluetooth feed the sound cuts out and the blue light starts blinking. Sometimes the sound comes right back and sometimes it doesn't. There is no standard cadence for it going out and can be a couple seconds to a couple minutes between sound cut out. My first thought was the audio cable but since it does it also on Bluetooth feed that takes away that thought. I can't find my receipt but I purchased it about 1.5 years ago from Best Buy for around $400. Thanks
