Sonos Arc with Nintendo Switch and LG CX

Hello,

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:

Sonos Arc

Sub Gen 3

2- Sonos One SL

LG CX

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)

eARC: On

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.

Thanks!

Are there any other devices going to the LG through HDMI? A pc, laptop, HDMI splitter, dock, converters, other consoles or streaming sticks? If so unplug those with the tv on. Then while keeping all other devices removed unplug the tv from the wall for 5 or 10 minutes. Turn the TV on and with only the Nintendo switch and nothing else plugged in give it a try.

If that doesn't work I would then suggest taking a photo of all your tv settings then perform a factory reset on the TV. Possibly even the Switch, though I know how much of a pain that can be to reinstall games.

I had the exact same problem as you, and even made a similar post.

I ended up finding a fairly good fix! Set the TV sound settings to passthrough, eArc on, bitstream on HDMI input. Also, in the Sonos app, make sure you turn audio compression settings to uncompressed. Not sure if it matters, but what the heck, right?

Then set the switch to surround mode. You won't hear anything, but go ahead and put the switch in rest mode. Turn the TV off. Then power the switch on with the controller while the TV is off. Proceed to turn the TV on and see if audio is working. It's worked for me twice now. It only seems to get out of sorts again if you unplug any HDMI inputs and mess up the eArc chain you've got going.

Hey @ChingisKhaan27,

So I tried your method, and unfortunately it didn’t work for me. I do believe this a LG CX issue though because I’ve found a workaround that will work temporarily too.

So if I set the Switch to Surround Sound with the normal TV settings (TV sound settings to passthrough, eArc on, bitstream on HDMI input) and start a game that supports 5.1 (like Mario Party Tennis) I can unplug the power cable for the TV from the outlet, wait a few seconds then plug the cable back in and turn the TV on. Doing this, the audio for the game will kick on using the Surround Sound, and the Sonos app will show the Multichannel LPCM. This only temporarily works until I change the input or power the TV off then back on, at which point it no longer works.

So just like you, I think this is an issue with the LG CX, and I’m hoping a future firmware update for the TV fixes this.

Thank you for your suggestion though!

Actually, as soon I posted my reply, your way did end up working. I set the Switch to Surround Sound, powered it off, then turned the TV off. I waited a bit, turned the TV on first, then the Switch and the sound started working on surround with Multichannel LPCM 7.1 showing in the Sonos app. But, the same thing happens with the method I found where as soon as I switch inputs then come back to the Switch, the sound no longer works.

Having similar issues to this too, which is odd because everything was working fine last week. Was playing mario kart with surround no issue.

Everything else works fine with surround from my pc to my ps5. I’m trying the ‘work around’ listed above and no luck.
