​Hi @Flaku

Welcome to the Sonos community and thanks for reaching out to us. Let me share some information to help you out. 

LCPM ​is an uncompressed audio format that provides high-quality audio to our eARC supported home theater devices. It supports up to 8 channels (5.1 and 7.1 surrounds are the most common). Getting audio depends on the physical source device playing the content and the format or output must be set to one of our supported home theater audio formats. Some players and game consoles use DTS audio format which is not supported by Sonos. Some have the ability to transcode DTS into a format that Sonos supports, such as Dolby Digital 5.1. You may also check this article about unsupported audio on home theater speakers for reference.

To take a look at your Sonos system, it would be great if you can submit a diagnostic and include the confirmation number in your response. I'd appreciate it too if you can provide us the make and model of your TV so that we can look up the information.

If you need help with any other information, please be sure to let us know. We’ll wait for your reply.
