Hi! I have a new roku soundbar hooked up by the hdmi cable that came with it to a new LG 4k smart tv. The soundbar audio is great except when I play discs in my magnavox 4K player. When I do this, I get intermittent audio cut outs at random times. The cut outs are around a half second each time. I have switched hdmi cables from the 4k player with no success. If I switch the audio to the internal tv speakers, the problem disappears. When I go back to hdmi arc for my audio through the soundbar the problem comes back...but only when using the 4k player. I have no audio issues when streaming. Sorry if this has already been asked. I didn't see it anywhere.
