Dolby Digital is the name for audio compression technology developed by the Dolby Labs. It provides a way to transfer data-heavy surround sound information between a source device and a home theater receiver or AV preamp/processor within a narrow bandwidth using various connection options. I don't think this is a problem with the Denon. Post-processing and converting the signal to analog form amplifies and sends the audio to the speakers. This reasoning arises probably because DTS surround sound is usually encoded at a higher data rate than the corresponding Dolby formats. Now that the audio output of the PS4 is configured, we also need to make additional settings to ensure we get bitstream audio during video playback. However, higher bitrates don’t always mean higher quality. For audio, a bitstream can convert sound into digital bits, and then that information is transferred from a source device to a receiver, and, eventually, to your ears. If you receive that content using a media streamer and connected to a home theater receiver using a digital audio connection (optical, coaxial, HDMI), the surround sound audio bitstream is sent to the receiver, decoded, and sent through the amplifier and speakers. Because some people have receivers that don't support TrueHD/DTS-HD/DTS/etc. Comparing DTS and Dolby Digital in consumer applications reveals that both standards are closer in terms of audio performance. A DVD, Blu-ray, or Ultra HD disc contains a Dolby Digital or DTS soundtrack encoded as digital bits. For internet streaming, a service, such as Netflix, offers a program or movie encoded in Dolby Digital or related surround sound format. That means the player will send out the audio signal exactly as it is, and leave it up to your receiver to do all of the decoding. Most Samsung Blu-ray Players have the Dolby Digital transcoding feature (since 2010 or so), including the BD-J5900 player from 2015. If you go with bitstream, it's POSSIBLE that the TV MIGHT output Dolby Digital(NOT TRUE HD) OR DTS(NOT DTSHD), some TV's Optical PASSTHROUGH strips out codecs, so it might give you some raw bad format. A bitstream is a method of transferring encoded audio signals of specific surround sound formats from a source to a compatible home theater receiver or AV preamp/processor/Power amplifier combination in a home theater. The maximum bit rates that Dolby Digital can support for DVD Video and DVD audio is up to 448kbits/s. I have tabulated the pro's and con's of DD/DTS in the matrix below. Here's How to Fix it, Windows 10 Start Menu Search Not Working? PCM will decode the 7.1 or 5.1 core only and bypass the Atmos encoding. Both Dolby and DTS offer surround sound codecs for 5.1, 6.1 (rare), and 7.1 setups, where the first number indicates the number of small surround speakers and the “.1” is a separate channel for a subwoofer. A home theater receiver or AV processor detects an encoded surround format sent to it. However, the 640kbits/s is only applicable to Blu-Ray discs. In that case, the TV will pass the bitstream signal out to the soundbar/home theater for decoding and amplification. Sounds very good, but I'm unable to bitstream the audio. As a result, the receiver will display Dolby, Dolby TrueHD, DTS, DTS-HD Master Audio, Dolby Atmos, DTS:X, or another format on its front panel display depending on which type of bitstream signal is decoded. I can also get it to bitstream vanilla AC3/DTS via directsound and Wasapi.

It's a bad answer but the best thing to do is upgrade, get a soundbar with HDMI, it'll give you better audio. Both audio formats are capable of achieving nearly similar results delivering surround sounds. They recreate object-based effects, such as a plane flying overhead or bullets zinging around the room, thanks to multiple audio signals aimed at set-ups with a greater number of speakers than the standard 5.1. There are other factors such as signal to noise ratio and dynamic range that some audiophiles might consider better in Dolby rather than DTS. Due to the higher bit rate supported by this format, DTS requires significantly low compression of about 4:1. Bitstreams are used in PC, networking, and audio applications. The two most popular ones supported by a broad range of high-end audio systems are DTS and Dolby Digital. So if you add a setting saying 'support passthrough Dolby/DTS' then the steamlink could just pass through the bitstream and not decode it. Here Are the Causes and Fixes. If the file uses hi-res secondary audio formats such as Dolby TrueHD, DTS-HD, or higher, the receiver will downgrade it to Dolby Digital or DTS because it’s trying to squeeze both types of formats into the same bandwidth. One technology used to deliver sound is a Bitstream (aka Bitstream Audio, Bit Stream, Digital Bitstream, or Audio Bitstream). The receiver/AV processor proceeds to decode the information based on instructions provided in the bitstream signal. My speakers say they support DTS and Dolby Digital. Which is best, sending PCM or bitstream from the player to the A/V receiver? The home theater receiver does the audio decoding of the incoming signal. I couldn't get consistent sound out of them using my HDMI devices and my TV (so sound coming from the TV through optical) regardless of whether I picked Linear PCM (default) or Auto on the TV so I took the TV out off the equation by connecting the PS4 directly to the speakers, setting it to bitstream so the speakers use the speakers … Bitstream Dolby Bitstream DTS . Dolby Digital and DTS are compressed bitstream formats, originally designed for disc media and were designed to work over a older coax digital (S/PDIF) or optical (TOSLINK) interace, though they can also be transported over HDMI too. By looking at the specs above, DTS seems to have an edge against Dolby due to the higher bitrate in all of its three versions. A bitstream can also be sent wirelessly via antenna or home network. A TV receives that signal, then transfers the bitstream to a soundbar, home theater receiver, or av preamp/processor using either a digital optical output or. I can only get PCM 7.1 sound out (sporadically) via Directsound. If you are connecting your surround system via HDMI then you should select 'Linear (PCM)' for uncompressed audio such as Dolby True HD and the like.
