We want to gather some details from people experiencing issues with playback of 7.1 LPCM audio streams on a Sonos Arc or Beam (Generation 2), via an LG television set. Specifically, when channels are playing from the wrong speakers - for example, but not limited to, if you hear dialogue only coming from the rear speakers, consistently.
If you have experienced this channel mis-mapping, please provide, in this thread, the following details:
Your LG TV model number
Your media source device name and model number or TV app that the issue was noticed on, and the name of the movie/show that was affected
Models of any other HDMI devices connected to the TV (if applicable)
The confirmation number of a Sonos system diagnostic submitted while the affected media was playing and 7.1 LPCM was reported in the Sonos app.
Thank you for your assistance.
