Sep 26, 2015 thank you very much for such a quick reply, I haven't made and changes to the sound setting except from 2ch to 5.1 dts. I just tried what you had said and still no luck, with the Microsoft driver i always have 2ch working but the 5.1 option in advance setting under default settings has vanished, if i install the lasted drivers from asus website it come back and 2ch sound works fine but 5.1 DTS.

The major network stations in the US broadcast AC3 5.1 audio. The TV receives the audio over the air, then downmixes it to 2.0. Another example is Nvidia Shield TV. If you play FLAC 2.0 music files via Plex, the client decodes the audio to 2.0 PCM before passing it to the attached receiver/soundbar/etc.
When Blu-ray hit the scene and snuffed out (outspent, really) HD-DVD in the mini format war, a new audio CODEC was needed to handle the many ways in which audio would need to be delivered in the high-definition era. DTS-HD Master Audio (formerly known as DTS++) became the new defacto-standard for the premium-level of on-disc HD audio. DTS-HD Master Audio is a 'lossless' audio format—using a variable bit-rate technology to deliver high quality audio, while keeping file sizes small and conserving bandwidth. It turns out the format was an impressive jump over prior iterations of DTS and was light-years ahead in how it could communicate and transmit the required 7.1 sound for Blu-ray.
DTS (the company) set out to make DTS-HD Master Audio the audible equivalent of listening to the master recordings. Technically-speaking, DTS-HD Master Audio carries within its file, two data streams: the original DTS 'core' stream and another stream that contains the 'residual' data that is made up of what's left from the original signal and the lossy compressed stream. The decoder is then able to use both to recreate an audio stream that is bit-for-bit identical to the original (i.e. 'lossless'). The encoding process is also very quick, and can be done in a single pass—something that is very important in the area of content creation and mastering.
Since DTS-HD Master Audio is essentially bit-for bit identical to the studio master, it can also be used as an archival format, but while taking up dramatically less storage volume when compared to uncompressed PCM audio tracks.

With respect to the Blu-ray format, DTS-HD Master Audio is becoming popular as it offers a significant space-savings, allowing for multiple languages to be stored on a single Blu-ray movie disc. This leaves more room for higher video quality, additional extras and special features.

DTS is also completely backwards compatible, but in a way that allows legacy AV receivers and other products to play back DTS-HD Master Audio files at up to 1.5 Mbps with up to 7.1 discrete channels at 96 kHz or 5.1 channels at 192 kHz. Here's what the various bit rates for DTS technologies look like:
The many different flavors of DTS and their corresponding bit rates
Note that DTS-HD can output audio at up to 96 kHz sampling rates, but DTS-HD Master Audio can output 5.1 at up to 192 kHz. DTS-HD master Audio also has a dramatic range where it can be encoded at a variable rate below 1 Mbps all the way up to around 24.5 Mbps. This is a flexible Mastering-level audio CODEC that has a lot of room for expansion and seems perfectly fit for all but the most aggressive surround formats of the future.

DTS-HD Master Audio (DTS-HD MA; known as DTS++ before 2004[1]) is a multi-channel, lossless audio codec developed by DTS as an extension of the lossyDTS Coherent Acoustics codec (DTS CA; usually itself referred to as just DTS). Rather than being an entirely new coding mechanism, DTS-HD MA encodes an audio master in lossy DTS first, then stores a concurrent stream of supplementary data representing whatever the DTS encoder discarded. This gives DTS-HD MA a lossy 'core' able to be played back by devices that cannot decode the more complex lossless audio. DTS-HD MA's primary application is audio storage and playback for Blu-ray Disc media; it competes in this respect with Dolby TrueHD, another lossless surround format. DTS-HD MA has enjoyed the greater share of this market since 2010,[2] with the notable exception of the TrueHD-encoded Dolby Atmos spatial surround format, which is more popular than DTS's competing DTS:X (encoded with DTS-HD MA).

Specifications[edit]
DTS-HD MA can store up to 8 discrete channels of audio (7.1 surround) at up to a 24 bit sample depth and 192 kHz sampling frequency (96 kHz for 6.1 or 7.1 surround).[3] Although DTS-HD MA, and the related DTS-HD, allow virtually any number of channels in the abstract,[4] these limits are imposed for practical reasons of limited storage and bitrate availability. A DTS-HD MA bitstream may have a bitrate no greater than 24.5 Mbps (instantaneous), of which no greater than 1.5 Mbps may be lossy DTS (as per the DTS CA specification).[5]
The Blu-ray specification stipulates DTS-HD MA as an optional codec, which means that some Blu-ray hardware may not decode it. This is the reason for the bifurcated nature of a DTS-HD MA audio stream; DTS CA, unlike its MA extension, is mandatory, so a player that is not MA-capable can automatically default to an MA-encoded disc's base DTS stream and simply ignore the supplementary data.[5]
DTS-HD MA is the encoding format for DTS:X, an object-based surround-sound format that competes with Dolby Atmos. A DTS-HD MA bitstream carrying DTS:X can contain up to 9 simultaneous sound objects, which are dynamically mapped to a user's speaker system during playback, unlike the rigid number and placement of speakers required by channel-based surround (a DTS marketing executive referred to DTS:X in an interview as 'whatever.1').[6]
Encoding process[edit]
DTS-HD MA is encoded in three steps. First, the audio master is fed to a DTS CA encoder, which generates the core (lossy) audio stream. Next, this lossy audio is decoded and compared to the master, with 'residual' data being recorded wherever the two differ. Finally, the residual data is compressed losslessly and merged with the core into one bitstream. A DTS-HD MA decoder simply performs this process in reverse.[7]
DTS-HD MA audio, including DTS:X audio, can be created and edited using DTS's DTS:X Encoder Suite. The DTS-HD Master Audio Suite served the same function before the introduction of DTS:X, and can still be used for DTS-HD MA that does not carry DTS:X.[8]
AV transport[edit]
DTS-HD Master Audio may be transported to AV receivers in 5.1, 6.1, or 7.1 channels, in full quality, in one of three ways depending on player and/or receiver support:[7]
- Over 6, 7 or 8 RCA connectors as analog audio, using the player's internal decoder and digital-to-analog converter (DAC).
- Over HDMI 1.1 (or higher) connections as 6-, 7-, or 8-channel linear PCM, using the player's decoder and the AV receiver's DAC.
- Over HDMI 1.3 (or higher) connections as the original DTS-HD Master Audio bitstream, with decoding and DAC both done by the AV receiver. (This is the transport mode required for DTS:X playback.)
TOSLINK does not have the bandwidth to carry DTS-HD MA (or PCM in more than 2 channels). A player using TOSLINK audio may output DTS-HD MA as either lossy DTS (which TOSLINK can carry) or downmixed stereo PCM.

DTS-HD Master Audio delivers sound that is bit-for-bit identical to the studio master. It can deliver audio at variable bit rates which are significantly higher than standard DVDs. DTS-HD Master Audio can provide up to 7.1 audio channels at a 96k sampling frequency / 24-bit depth or 5.1 audio channels at 192 kHz that are identical to the original master. The DTS-HD Master Audio bit stream also contains the DTS 1.5 Mbps core for backwards compatibility with existing DTS-enabled home theater systems, and delivery of 5.1 channels of sound at twice the resolution found on most standard DVDs.
