I have a Beam, 2 Play Ones and a Sub Gen 3 set up and am experiencing sound dropouts when watching live TV only. The sounds drops out for a split second and then comes back in.
I do not experience any dropouts of audio when watching recordings on my Sky Q box or when watching Netflix or Prime through the apps on the Q box.
I had a HDMI cable running from the Sky Q box to tv HDMI port 1 and the Beam connected to port 2 (Arc). In an attempt to resolve the audio dropouts I have tried:
1) Unplugged all other HDMI cables apart from Sky Q and Beam
2) Changed the HDMI cable from Sky Q box to TV to 4k cable
3) Tried optical adaptor supplied with Beam
4) Played about with LG TV settings as suggested in other posts (PCM, HDMI control off etc)
I am still experiencing the audio dropouts. My diagnostics code is 633986811.
Thanks.
