DOLBY DIGITAL SURROUND DRIVERS

If you have a system with in-ceiling speakers or up-firing drivers in a soundbar, you can enable Dolby Atmos on your Xbox for immersive, overhead sound effects. How to Set Up Dolby Atmos with a Soundbar or Home Theater System So each approach has its own pros and cons. If you choose 5.1 or 7.1 uncompressed, you'll get higher quality audio, but you might not be able to use certain features on your receiver (like Dolby's 'Night Mode,' which requires bitstreaming Dolby audio). This HDMI audio setting applies to surround sound-compatible games as well as apps like Netflix. No matter which of these you choose, audio from Blu-ray discs will be bitstreamed in its default format, provided you leave the default settings under Settings > Devices & Connections > Blu-ray.

If you have a Dolby Atmos system, skip to the section below.

(Some systems may only support one or the other, but many will support both.) In that case, you can choose Bitstream Out and select DTS Digital Surround or Dolby Digital as your bitstream format to get proper surround audio.

If you have a 5.1 or 7.1 system with your Xbox plugged into your TV, with audio routed to your speakers over Optical or HDMI ARC, uncompressed may require too much bandwidth for your connection.

If you have a 5.1 or 7.1 system with your Xbox plugged directly into the receiver or soundbar, choose 5.1 or 7.1 uncompressed.

Here, you'll want to select the options that fits your system best. Head to Settings > General > Volume & Audio Output and look for the options under Speaker Audio. While we can't delve into every combination of gear, we can point you in the right direction.

DOLBY DIGITAL SURROUND TV

Which settings you choose here will depend heavily on your setup-what formats your TV and sound system support, how they're hooked up, and so on.

DOLBY DIGITAL SURROUND SERIES

In the next section, we'll find out about the clever trick that makes this possible.The Xbox Series X and S support multiple surround formats, whether you're using an AV receiver with dedicated speakers or a sound bar system with rear satellites. In this system, originally used in the quadraphonic home stereo recordings of the early 1970s, four channels of audio information are encoded into two tracks. In order to allow for four separate audio channels, they developed a special 4-2-4 processing system. When Dolby engineers started working on the new format, they figured out they would only be able to fit two optical tracks in the available space. The real innovation of Dolby Stereo is how so much audio information is squeezed into a small space on the film. (See How Home Theater Works for more information.)

DOLBY DIGITAL SURROUND PRO

In 1987, Dolby introduced Dolby Pro LogicВ®, which had an additional channel for a front central speaker. The speakers are set up in the same basic way as in a theater, except the original home Dolby system only had three channels - left speaker, right speaker and rear speaker. The audio channels are encoded as magnetic tracks on video tape or broadcast as a television signal, rather than put down as optical tracks. Dolby Surround reproduces the effect of Dolby Stereo in the theater, but it works a little bit differently. In 1982, Dolby launched Dolby Surround В®, a version of Dolby Stereo for home entertainment systems. The subwoofer channel in both analog and digital surround-sound systems is sometimes called the low frequency effects (LFE) channel. Many moviemakers use the subwoofer to create a powerful rumbling in the theater, shaking the audience when there is an explosion or earthquake on-screen. In later versions of the surround-sound system, theater owners could hook up a subwoofer to handle extremely low-frequency sounds (a crossover unit can separate out these sounds from both audio tracks). Later movies followed the ' Star Wars' model, using the surround track to create fantastic effects, as well as fill in background noise to establish a scene's setting.
