One reason of DTS support for Sonos

I think Sonos owe Samsung a deal of gratitude, I use our Samsung Blu-ray to transcode DTS to DD5.1 frequently, also use it for Netflix.

Might have to by a new Samsung Blu-ray player to keep "in stock".

I still feel we should keep pushing for DTS support in the product itself .. I am still switching to tv speakers every time I watch a DTS movie.. just does not make sense to me

Let me again quote from this article:

Digital audio signals, such as 5.1/7.1 multi-channel PCM, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS:X, and Auro 3D Audio cannot be transferred via Digital Optical connections. To transfer these types of audio signal formats you need to use HDMI connections.

The large majority of TV speakers sold by Sonos continue to be powered only by an optical connection. It is only their latest TV speaker, the Beam, which can handle an HDMI-ARC connection.

Just on a point of detail, though, optical connections do support regular DTS, which is the main topic of this thread. My decade old AV amplifier happily handles DTS signals this way, since it lacks HDMI inputs of any kind.

I agree with the other poster. I have always listened to DTS via optical so see no reason why this should not be possible for the playbar?

Agreed. I am even looking at the Yamaha soundbar with HDMI 2.2 and decodes everything. Sonos was first, now they are getting left way behind. I would buy a Soundbase or a new Playbar if they had HDMI 2.2 with 4k passthrough and all the other decodings. DTS, Dolby ATMOS, Dolby Digital Plus and all the other popular ones.

I think there is a great misunderstanding of what sound formats are passed from the HDMI ARC and Digital Optical output on televisions. DTS is not passed by many televisions via HDMI or Digital Optical. DTS is a sound source from DVD and Bluray. IMO, the difference between DTS and Dolby Digital would be marginal at best through a soundbar. Same for Dolby Digital and Dolby Digital Plus. Since most folks using Sonos for movies likely stream, it’s a non factor.

Here’s a helpful link of current televisions and the sound formats they pass:

Agreed. I would jump right on a complete update of both of my Playbar's if the received HDMI inout like the Beam, and DTS, Dolby Atmos, and the other very upgraded sound support and decoding. Sony, Tamaha, and others are doing it and jumping o sales for SONOS, SONOS went public and have to answer to shareholders now, maybe they should start to listen. I own shares of this company

The Beam doesn't have HDMI input. It uses HDMI-ARC. It actually sends HDMI out (a screen saver) to the TV, with audio returning to the Beam over the return channel.
