Surround Audio setting doesn’t change surround levels on Era 300s

@Corry P Some Reddit users noticed that the Surround Audio TV Level setting doesn’t actually change the rear surround levels on the Era 300s. So I decided to test it for myself.

When playing a Dolby Atmos 7.1.4 Test Tones video and a DTS 7.1 Sound Check video, the TV Level setting has no affect on the levels of the rear surround channels. It only changes the side surround levels.

When playing a Dolby Atmos 5.1.4 Test Tones video, the TV Level setting has no affect on the levels of both surround channels. BUT when playing a DTS 5.1 Sound Check video, the TV Level setting DOES change the levels of the two surround channels.

NOTE: The DTS audio is being played as Multichannel PCM from a Blu-ray player.

Is this a bug in the software?

Thank you for posting this. I am the original author of the Reddit post. Thank you for also posting this here and doing additional testing of your own. I also created a thread here in this community before I saw your post.

I truly believe this is not working as intended. Hopefully we can get an official response.

Hi @GuitarSuperstar

Thanks for your post!

Several of the settings sliders are not functioning on iOS devices - we are aware of this and are working on a fix.

If you happen to have an Android controller, please adjust settings on it in the meantime.

I hope this helps.

Interesting. So if I do my normal Trueplay with my iPhone and then switch over to an android device I can adjust the surround levels on there and it will raise both side and rear surrounds as opposed to only the side surrounds when I do it on iPhone?

Used an Android device to change the surround levels in the app and the issue is still the same; side surrounds change in volume with slider while rear surrounds do not

@GuitarSuperstar what are you using as test tones? I tried an mkv file but i noticed my up fire speakers are not producing any sound and the inner drivers from both of my eras are not producing any sound either. I have removed them as surround and played the audio again but still have the same experience. I wonder if it’s the audio that’s corrupted or simply not meant to be tested with the eras and I’d like to try a different source.

I am using test tone videos from official Dolby Atmos and DTS demo Blu-ray discs. But you can download these MP4 files from Dolby’s website.

These files can also be played in Dolby Atmos directly from an iPhone to an Apple TV 4K or Roku Ultra via AirPlay.

My atmos speakers were doing the same and not producing any sound as well. When I unpaired the 300s as surrounds and re-paired them, and after true-playing again, I do hear the Atmos up firing speakers during the 7.1.4 test file.
