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. 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. 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.
