Multichannel PCM on Arc

Are you really not supporting multichannel PCM on the newly announced Arc?

Why? It’s not a licensing issue this time.

It seems like there is always something missing with your home theater products.

Hi all,

We hear you. With a software update today, Arc now supports multi-channel LPCM, bringing new immersive sound experiences for gaming, Blu-ray discs, and more. To get support for multi-channel LPCM on Arc, download the latest Sonos S2 update from the app store and then update your system in the Sonos S2 app. After updating the app, go to Settings > System > System Updates > Check for Updates.

All the best,

Ditte

@GuitarSuperstar Buenas otra vez, probé con el cable directamente de sonos arc y sigue saliendo digital plus, ahora le he añadido dos sonos one SL y sigue poniendo 5.1 puede ser porque tenga que modificar algo desde al app de sonos? Me sale lo que adjunto en la foto y no se si tengo que quitar la compresión. Me estoy volviendo loca de no saber que pasa.

@Madejón La configuración de compresión en la aplicación Sonos solo afecta la entrada de línea, así que manténgala configurada en Sin comprimir.

¿Está activado Simplink (CEC) en la configuración de su televisor?

¿Qué películas/programas específicos has probado en Netflix?

@GuitarSuperstar Simplink se establece de manera automática al activar hdmi arc, te paso fotos con el manual que he leído en la tv.
He puesto en Netflix Ratched en versión original y por fin me sale Dolby Atmos! Pero en español no.

@GuitarSuperstar - Sonos just released a 13.2 update with bug fixes - I wonder if you wouldn’t mind checking if multichannel PCM 7.1 mixing issue has finally been resolved?

A Sonos staff member, Corry P. stated last week this was not addressed in the latest update.

@madhav @khaz22 @Corry P I’m happy to report the LPCM 7.1 to 5.1 down mixing problem seems to have been fixed with the latest update.

I played the DTS Sound Check from a DTS demo disc with a DTS-HD Master Audio 7.1 track. Before the Sonos update, my rear speakers didn’t play the test tones from the left rear and right rear surround channels. I would only hear the test tones from the side left and side right channels. Now I can hear the test tones from all four surround channels playing from my rear speakers.

The only thing that is still incorrect is the Sonos app is showing “Multichannel PCM 7.1” when I play the 5.1 test tones DTS Sound Check. But all channels are playing through each speaker correctly.

Hi @GuitarSuperstar

I’m glad to hear you’ve spotted an improvement! As mentioned on another thread, we’re still not announcing it as fixed though. I’ve checked some internal documentation and it’s still not official. However, if it’s usable it’s usable - great!
