I recently tried using my Nintendo Switch for the first time since getting my Sonos setup, and I can't figure out how to get the Multichannel LPCM to work on it.
My current setup:
Sub Gen 3
2- Sonos One SL
My Sonos app version is on the most current version of 13.1.3, and my Sonos system is on 13.1.1
The LG CX is also on the latest version of 03.23.06
My TV settings are as follows:
Sound Out: HDMI ARC
Digital Sound Out: Pass Through (Have also tried PCM and Auto)
HDMI Input Audio Format: Bitstream (Have also tried PCM)
On the Switch under TV Settings, when I set it to Surround Sound and run a test, no sound comes through, and the Sonos app either shows No Signal or Silence. When I set to Stereo, sound will work, and the Sonos app will show Stereo PCM 2.0
I've seen other forums where people will say that Multichannel LPCM works for them using a Switch and LG CX, so I'm wondering if there is something I'm doing wrong, or if there is something I may have missed.
I have tried different HDMI cables with the Switch and verified that my Arc is plugged into the eARC HDMI port (HDMI 2) on my TV. I have also tried multiple power cycles on the TV and Switch.
Any assistance is appreciated.
