Sonos Arc with Nintendo Switch and LG CX

 

These settings give me multi channel 5.1 with the full Arc system. The Switch is set to surround.

(Also, I named this Sonos set up "The garden" as there are 22 alive house plants in the room).

 

Lame question, but is your HDMI Input “Bitstream” or “PCM”? 
 

thank you!

For clarification I have my tv set to bitstream. My bad on having PCM highlighted with the remote in the photo. Selecting PCM only gives me stereo sound with game consoles.

Oof! My dang setup only gives 7.1 with these settings and Switch, Arc, and LG

Thank you for the reply!

Hey Everyone!

Sorry for the delayed response, and @Tylertron21, thank you for the screenshots. Here are some of mine:

Please let me know if everything looks good on my end, or if I may be doing something wrong.

Thanks!

@rflurry512 Have you tried unplugging the Arc, Switch, and LG from power for a couple of minutes?

OP do this while also unplugging every HDMI to the CX. Leave the devices fully unplugged from the wall outlet and tv inputs for 10 full minutes. Set a timer to return to plug everything back on.

Start with the Sonos, plug your full Sonos system in to the wall and allow it all to power on.

Now the CX, turn on the CX, let it fully power up. Plug up the Nintendo and also power it up.

Now plug in each HDMI one at a time with the Arc being last in the chain. Wait a minute before playing any audio once you select the Switch input as the tv automatically switched from internal speakers to earc.

See if this woowoo magic works. This method fixed the audio lag issue I use to have with my tv and the Arc.

Hey all,

So here are the steps that I tried:

1. Powered off the TV, Arc, Switch, etc.
2. Unplugged all devices from the wall outlet (TV, Arc, Fire TV Stick, Switch dock, cable box) and waited around 15 mins
3. Plugged the Arc back in, and waited for it to fully come back up
4. Plugged the TV in, and powered back on
5. Plugged in the Switch, and the rest of the devices back into the wall outlet and powered on the Switch
6. Plugged the Switch HDMI cable into the TV first, then the cable box and Fire TV Stick one at a time. Changed to the Switch input
7. Plugged the Arc into the eARC HDMI port on the TV (HDMI 2)

After doing these steps, I waited a bit then tried switching the sound on the Switch from Stereo to Surround. Unfortunately, I was still not able to get any sound to come through when running the test after changing the sound. I also could not get any sound running a 5.1 supported game, and the Sonos app showed as No Signal (like my above screenshot).

I have also tried plugging the Switch another HDMI port to test, and had no success.

I’m not really sure where to go from here troubleshooting wise, but I’m willing to try any further steps you all may have.

Thanks!

Is it possible to try another Switch and dock with your tv? Maybe have a friend bring theirs over. I normally don't suggest these basic ideas for people but, have you tried another HDMI cable? I am using the one that came with my Switch.

With

HDMI Input: Bitstream
eARC: On
Digital Sound Output: Passthrough

your Sonos app should be showing Multichannelp PCM 7.1 in the app. The 7.1 is just an LG TV problem, the speakers will still be getting the correct 5.1

whats odd is that you’re not even getting the 7.1 to show up. Do you have every HDMI Input set to bitstream? Make sure to do that. Also double check that the Sonos Arc is plugged into the ARC HDMI port and turn eARC off then on again.

also make sure your sound out is only set to ARC. Not ARC + TV speaker or any other combination.

Also maybe buy brand new HDMI 2.1 cables just to be 100% certain every cable in this chain is up-to-date

Hey all,

@Tylertron21  - So I went ahead and tried both my brother’s Switch and dock with the same results. I have also tried 3 different HDMI cables including the original one that came with the Switch.

@ejihnen  - I included some screenshots above of how my settings are. One of the screenshots shows that the HDMI Input Audio Format for each HDMI input is set to Bitstream, another screenshot shows where the Sound Out is set to HDMI ARC only, and I did double check and verify the Sonos Arc is plugged into the eARC port (HDMI 2) on my TV. Here’s another screenshot to show this:

Per your suggestion, I did toggle off eARC and wait a bit, then toggled back on and tested with the same results. As for the HDMI cables, I am using the original HDMI cable that came with the Sonos Arc that goes from the Arc into HDMI 2, and I have tried 3 different HDMI cables for the Switch, all with the same results.

I do have one more thing I can think of trying which I will probably try later on this week, but I’m open to anymore suggestions prior to then.

Thank you again for the continued responses and recommendations!
