I have my PC connected to my 65" Q70T via HDMI and an older Pinnacle Speakers sound bar connected via new amazon optical cable. Occasionally when starting a video or other moving picture with sound file (gif with sound) there will be a loud popping sound from the sound bar. It does not do this if the sound bar is off and I am using the TV speakers. It doesnt do it all the time or with all videos/files. Any ideas?
