Sonos Arc & Vizio TV - audio dropouts

Question

Having issues with my Vizio M507-G1 and just-purchased Sonos Arc and Sub Gen 3. Everything is up-to-date.

Essentially, when I configure the Digital Audio Out to anything but PCM (which is just stereo...), the audio breaks up and there is a lag I cannot fix. Didn’t do this with previous Vizio soundbar.

Does anyone have a similar setup with this all working how it should that can share their settings, please. My current ones are below:

Speakers: Off

Volume Control Display: On

Surround Sound: Off

Volume Leveling: Off

Balance: 0

Lip Sync: 0

Digital Audio Out: PCM

Analog Audio Out: Variable

Thanks in advance.

Set Digital Auto Out to Auto and unplug your TV and Arc for a couple minutes and see if that helps.

Also be sure the HDMI cable is connected to your TV’s HDMI ARC port which I believe is HDMI 1.

Is CEC Enabled or set to ARC Only?

Thank you! I’ll definitely give that a shot and hope it works. I wish I had stuck with Sony when “upgrading” TVs as I feel like this Vizio has been pretty problematic occasionally.

CEC is set to “Enabled” as I have an Apple TV connected also.
