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?

        Hi @GuitarSuperstar et all

        We have been unable to reproduce this issue with Atmos playback on Arc and Era 300s. I would encourage you to remove your Era 300 surrounds from your Arc and add them back again - if that does not resolve the situation, I recommend you get in touch with our technical support team in order to go through some troubleshooting steps and to provide some contextualised diagnostics. Please feel free to mention this thread when getting in touch - it’ll reduce the amount of explaining you’ll need to do

        I hope this helps..

        @Corry P When your engineers play the 7.1.4 test tones file below, are they able to control the volume of the rear surround channels (inside drivers) of the Era 300 using the Surround Audio level sliders?

        And are they unable to reproduce the issue with 7.1 and 5.1 playback too?

        Hi @GuitarSuperstar 

        I’m told the effect is not as pronounced as it is with other units used as surrounds, but that it is there and noticeable. 5.1 was not tested at that time and by that person.

        Could you please submit a support diagnostic, change the surround levels, then submit another and share both numbers with me here? Thanks.

        @Corry P The effect is there, but the issue is the Surround Audio level slider doesn’t change the level of the two inside drivers on the speaker. Those drivers remain at the same level regardless if the TV Level slider is set to -15 or +15. The TV Level slider only changes the volume of the two outside drivers. Is this by design?

          Hey @Corry P. Do you have an update on this? Did the diagnostics reveal anything? Is it by design that the inside drivers of the Era 300s remain at the same level regardless of what setting the Surround Level sliders are set to?
