fixmy1200

Hi folks. We have a Klipsch 1200 that a family member purchased for us (second hand i think). It constantly disconnects, so far i have tried HDMI ARC, optical, spotify, bluetooth. Errors are HDMI ARC We can watch tv fine for minutes/hours/days then all of a sudden the audio just stops coming out of the speaker. Swapped to Optical Exactly the same problem, regardless of HDMI input (tried them all). Spotify. Sometimes connects within a second. Other times connecting takes minutes. Will play half a song, 10 songs but at somepoint it just stops. Spotify app (tried multiple phones and laptops). Still shows it playing through the sound bar for a minute or so until it realises the bar has given up. Then i can select the device and it starts playing again. Is this a common problem or is the sound bar just faulty? Any help appreciated.
