Missing "Attenuation overrides" for Steam Audio

Steam Audio guide says that you need at least 4.19 to get it work, and I have 4.19 Preview 2 from Epic Launcher.
Guide here says to go to Attenuation overrides under Attenuation tab, but, that Attenuation overrides missing for me.

Maybe I missing something? Or guide itself outdated already?

Maybe all of this applied when I did this?

To all who are too have these differences as me:

Go to Edit > Project Settings… > Scroll all the way down to Plugins section > Click Steam Audio > In Indirect Spatialization Method set HRTF > Press Shift+6 > In showed up menu click Add All > Click on any sound effect (not in Content Browser) > Under Attenuation tab uncheck Override Attenuation (check only in special cases) and create asset for Attenuation Settings > Open that > Under Attenuation Spatialization tab in Spatialization Method set Binaural > Under Attenuation Air Absorption tab check Enable Air Absorption > Under Attenuation Occlusion check Enable Occlusion > Under Attenuation Plugin Settings in Plugin Settings create assets for Spatialization and Occlusion (click on +) > In created asset for Spatialization in Spatialization Method set HRTF, and in HRTF Interpolation Method set Biliniar > In created asset for Occlusion in Direct Occlusion Mode set Direct Occlusion, Frequency-Dependent Transmission > In Direct Occlusion Method set Partial.

After all of this stuff hear sounds will be much better. Remember - this is basic Steam Audio setup on your game. You can read full guide and watch videos on youtube to tune every single detail.

And don’t forget to set Attenuation Settings in every sound to your asset.

I’m having this same issue. I’ve tried the answer below but most of the steps require setting checkboxes that don’t exist on my asset. The Shift+6 step didn’t do anything on my machine.

I found the solution! As mentioned in the documentation (https://github.com/ValveSoftware/steam-audio/blob/master/unreal/doc/phonon_unreal.md):

Next, you must modify the command-line arguments used when launching the editor using the shortcut:

  1. Right-click the shortcut to the Unreal editor and click Properties.
  2. In the Shortcut tab, under Target, add -audiomixer at the end of the command line. (…" -audiomixer)
  3. Click OK.
