No ATMOS

Be sure your FiOS audio settings are set to:

Audio Format > Surround

Dynamic Range > None

Audio Passthrough > Enable

First, thank you.

Audio Format was already Surround

DR was Light, now None

AP was already enabled.

Still not ATMOS (at least not showing in app)

I’m assuming you have a Netflix premium account which is required for Atmos audio.

Does your TV’s native Netflix app pass through Atmos audio?

Thanks, again for input.

Yes, Netflix premium account.

Just tried Netflix through TV app, TV screen says ATMOS (just like FiOS) but nothing on S2 screen.

Also tried Netflix through FireTV stick. ATMOS is not displayed on TV (and obviously not in S2) through FireTV stick.

FYI- Just put on Star Wars on Disney+ through FireTV stick and I am seeing the ATMOS logo in S2 app.

Something isn’t right. When you check for the Atmos logo on the Sonos app, are you backing out of the TV control screen and coming back to it AFTER the audio has started playing from the Atmos content?

What specific Fire TV Stick do you have?

According to this guide, Atmos audio from Netflix only works on the most recent Fire TV Stick: https://www.nakamichi-usa.com/the-ultimate-dolby-atmos-guide

I am only changing TV input (TV vs FiOS vs FireTV Stick). I left the app alone and when I switched to Disney+ (through FireTV Stick), the Atmos logo appeared in the S2 app.
