I can see similar stories of this issue popping up here and on other forums but can’t see any resolution.
example:
I’ve had the beam 2 a few weeks and started to notice a few days ago. First thing I noticed it on was watching Reacher on Prime Video.
Two scenes across the series generated similar to what is described in this thread - squeaky metallic noise over voices which was really high pitched and coincided with talking. A few scenes later it was gone but it was really noticeable at the time and replying the scene it comes back.
LG G2 TV - eARC HDMI - Oututting Dolby Atmos.
Beam Gen 2. No surrounds.
is this is a known issue or a hardware defect? Seems like some people have tried multiple units with the same issue?
