LG C1 and LG SN10Y Soundbar no sound

[Beilish]

Hello everyone, I need help understanding what I'm doing wrong.

 

I have:

• LG C1
• LG SN10Y Soundbar
• PS5
• Nvidia Shield Pro
• 3x HDMI 2.1 cables.

I connected them like this:

1. Soundbar eARC -- > TV HDMI 1 (eARC).
2. PS5 --> TV HDMI 2 (Also eARC)
3. Nvidia Shield --> TV HDMI 4 on the back of the TV (Also eARC)

Settings:

• Enabled eARC in TV settings
• Sound output is on auto (tried Passthrough as well)
• Soundbar and TV on latest firmwares.
• Soundbar is on eARC mode (tried HDMI1/2 also)

I don't get sound from either the PS5 or the Nvidia Shield. When I plug the PS5 and Shield to the soundbar, everything works fine, but then my PS5 says it doesn't support VRR.

 

I don't know what else to do, am I missing something?

You should be plugging your sources into your TV, which will hand the audio off to the soundbar through earc. Normally the tv makes the switch automatically but you may have to go into the tv settings to enable earc. I’ve also seen weird behaviour with the ps5’s audio settings so it might be worth checking that out if you continue to have issues.

Thank you, I did that and edited the post to reflect my changes.

I get no sound still, not sure what I'm missing.

For TV settings, check if HDMI input audio format is on Bitstream, and digital sound output on Passthrough. Just a reminder LG X, 1 and 2 series do not support DTS decoding & passthrough.
