ERA's 300 center channel not working if connected as surrounds to ARC/SUB

As i pointed out in my Dolby ATMOS TrueHD test file analysis. There is this weird behaviour, where ERAs center channel is not playing anything at all. Only speakers that are involved are upfiring ans side speakers.

This is also true for ATMOS music played via Apple Music or even Stereo music via Apple Music or Spotify. Center channel is just “dead”.

Is this intentional or a bug?

Just to give this post a reply, Sonos have confirmed that in surround configuration, the front tweeter is not used.

It is only used when they/it is used for music playback outside of a HT set up.

Just to clarify, is the centre channel inactive when listening to music on setup connected to a soundbar?

The center channel will never ever fire, regardless of whether you are listening to your TV or music, so long as the 300s are configured as rears. No way to switch that in the app, as silly as this sounds.

Exactly.

I’m still a bit confused as to whether the front channel is working at all for music alone. Has anyone got their 300 set up only as one speaker to play music but can hear the front channel working? I have this exact set up and I still have no sound from the front. I’m tempted to send it back for a refund.

Hi @Henrique Gusso 

I’d encourage you to get in touch with our technical support team with any issues you notice.

The front-facing driver is only disabled when the Era 300 is used as a surround speaker. The front-facing driver is enabled when used as a stereo pair with another Era 300. Two Era 300s as a stereo pair sounds fantastic especially when playing music in Dolby Atmos.

This is especially punishing on gamers because you no longer can receive precise directional sound from the surround speakers.

For the time being, I have to put the Era 300’s outer speakers close to a wall so it has some clarity to it. Please make an option to turn these speakers on, it would be a shame to have to return these.

I’ve now tuned my single Era 300 (to play music only) using advanced tuning via IOS. The front channel is definitely working now and the sound is amazing!
