Hello! I just wanted to ask if others have experienced this potential bug; when running Era 300s as surrounds for an Arc Ultra in music mode, the Full/Ambient surround settings change the the sound of the Era 300s even when I’m playing Atmos music (this is through Apple Music on the Sonos app). The description of the setting, however, states that Full/Ambient shouldn’t apply to Atmos playback. I’m curious to know which setting, if either, is the intended EQ for the surrounds.

Possible Bug with Era 300 Surrounds

Since we don’t know what you are hearing your best next step is to run a diagnostic within 10 minutes of the sound change you describe. In fact it might be advisable to run a diagnostic before it happens to establish a base-line and then perform your test with Dolby Atmos and run the second diagnostic.
Record the reference ID’s for both diagnostics but do not post them in the forum (here). Call Sonos Tech support to discuss the results.

As far as I’m aware, the Full/ambient setting is only in effect when the surround speakers are receiving surround data from the ARC or optical line in on the home theater ‘front’ device. That setting would not be in use when there is any WiFi streaming going on.
I think I said that backwards…and not easily understood. My sincere apologies.
The Full/Ambient switch is only in use when WiFi streaming is in effect, via the Sonos Controller, AirPlay 2, or Bluetooth, to the ‘front’ device of the Sonos ‘Room’
That switch is ignored when the digital input is used (either an optical on older devices, or ARC on newer devices).
Hopefully, that makes more sense.

All audio coming via ARC or Optical is treated as TV audio.
The Full/Ambient options are specifically for Music playback which is stated in the app.
I ‘want’ to separate those as inputs, rather than TV, but yes, you’re right.
I think the snip below best sums things up regarding Full/Ambient settings for music play back with Arc Ultra and surrounds. Note that when listening to music in Dolby Atmos the settings don’t apply. The sound does change (as it should) for the Era 300’s when listening to Dolby Atmos recordings vs regular stereo regardless of the settings.
I no longer use Apple Music, but when playing atmos from Amazon Music, switching between Full/Ambient has no effect on the audio. There is no “intended” setting as neither apply to atmos music playback.
Maybe another user will be able to recreate your experience with Apple Music…
