If you want more you will have to buy several independent speakers and connect them to an av amplifier compatible with the latest audio formats.įor DTS, Dolby Atmos and the like, I agree. Sonos has the best audio decoder in the market. The 640 kbps bit rate, which is higher than the standard 448 kbps used on DVDs, is fully compatible with all existing Dolby Digital decoding products such as A/V receivers, and can provide higher-than-DVD quality from Dolby Digital Plus soundtracks when played back through existing systems.Ĭode: I think you do not need More, if what you want is a sound bar. Dolby Digital Plus soundtracks are easily converted to a 640 kbps Dolby Digital signal without decoding and reencoding, for output via S/PDIF. Is Dolby Digital Plus content backward-compatible?īecause Dolby Digital Plus is built on core Dolby Digital technologies, content that is encoded with Dolby Digital Plus is fully compatible with the millions of existing home theaters and playback systems worldwide equipped for Dolby Digital playback. are backward-compatible, however, I think the TV set has to support the conversion. I don't know the standards, so not sure what the default behavior should be in that case. If your input device cannot do that, it is up to the input device what you get: either it will revert to stereo, or still send DD5.1+ in which case you will have no sound. It requests via HDMI handshake, yes, but it does not do the conversion. They never did on DTS and I do not see any sign of change in terms of Dolby Digital Plus. Here is hoping thay Apple will continue supporting the excellent on-the-fly converting capabilities of the Apple TV (or LG/Sony releasing a decent Oled TV-set with similar capabilities!) - cause I am sure Sonos will not be changing their strategy on this. This is coming from a long-term Sonos-fan owning (and having done so since their respective dates of release) each of the Playbar, Playbase and Beam.Īll of them are great products, but getting the most out of them is becoming increasingly more difficult with the widespreading of unsupported file formats. ![]() Dolby Digital and avoids the problem this way, but generally - unless you use an Apple TV, Playstation, Xbox or similar - you will not be able to get full surround from Netflix and many other streaming services from a Sonos-device - including the Beam. Some build-in apps on TVs only stream in e.g. I even put up a specific thread to identify any TV-sets with this feature - but was out of luck.Įxcept for some Blu-ray-players, Xbox/Playstation and Apple TV, TVs and streaming-boxes (including popular choices as Chromecast and Fire sticks) are not able to downmix Dolby Digital Plus or DTS on the fly. I have yet to find a single tv-set with this feature. Dolby Digital Plus to Dolby Digital and that handshake will force the TV to do so. Some people seem to be of the impressions that most TV-sets can downmix e.g. In this case, handshake will ensure that the Beam receives the best possible, supported format being stereo (PCM). With Chromecast and most other systems, only Stereo and Dolby Digital Plus are available for Netflix. However, Netflix for instance does typically not include several types of audioformats in their streams. Dolby Digital Plus, Dolby Digital and PCM is available, the TV will send Dolby Digital to the Beam. Handshake simply ensures that the TV will provide the best possible sound available that the Beam supports. Handshake does not mean that the Beam can downmix Dolby Digital Plus to Dolby Digital - the Beam cannot do that. The Beam supports PCM and Dolby Digital but not Dolby Digital Plus. In my understanding, handshake is simply a feature enabling the Beam to request supported fileformats.

The Sonos Playbase and Playbar only have an optical connection.
