Hello,
I have a Sonos Beam connected to a Samsung Series 8 through optical. Recently we have found that anytime we are streaming something on our Firestick (ie Netflix, Disney+), the audio will stop intermittently for a second or two and then resume. This occurs every hour or two. I am not sure why this is occurring, as we have everything connected correctly that I am aware of and streaming with internet capability up to 1000 mbps.
