PCM is not of a better quality than bitstreamed audio formats and the bitstreamed package is where the PCM data was sourced from. The only difference is which device is used to decode the compressed format to get the uncompressed PCM data. If you bitstream then it is the AV receiver that is doing this decoding..
In this way, what is difference between Bitstream and PCM?
For digital optical/coaxial connections, while the bitstream output option can send a standard Dolby Digital or DTS 5.1 surround sound signal to your receiver for further decoding, the PCM option will only send a two-channel signal.
Similarly, what is the best HDMI audio format? The highest quality possible for ARC is DTS and DD/DD+. If you are plugging your android box into your tv you should use passthrough for everything up to DTS, then send anything higher (i.e. the lossless) as 7.1 PCM and set your tv Digital Output Audio Format to DTS.
Also Know, what is audio bitstream?
Bitstream encoding is a core technology that is used in home theater audio. 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 a variety of connection options.
Is PCM surround sound?
PCM can carry surround sound, but it cannot do so over an optical cable—the optical cable can only carry stereo PCM (using TOSLINK, the home stereo standard). To send surround PCM, you'd need to use an HDMI cable (or alternatively displayport on a PC), which carries both the video and audio signal.
Related Question Answers
Should I use PCM or Dolby Digital?
Yes, PCM is uncompressed audio, whereas Dolby Digital is compressed, which compromises quality for space. Dolby TrueHD, on the other hand, is a lossless audio format, like a zip file, which is identical to PCM, in theory (I won't get into that debate). That's like asking if CD's sound better then MP3's.What is PCM audio setting on TV?
Pulse-code modulation, abbreviated "PCM," is a form of digital signal that is used to represent analog data. Depending on the model of television you watch, switching the audio output to PCM may improve the sound quality of the television's speakers.What's the best audio format for ps4?
And QUESTION TWO: after extensive Google searching, it seems the consensus is that Linear PCM is best for HDMI/5.1/7.1 sound for "lossless" audio, but why is it that Bitstream (Dolby) sounds "best" to me – and I mean "best" because in most games, using that setting has a more "real" surround sound effect.How do I set up PCM audio on my Samsung TV?
Troubleshoot no sound through the Optical output - Press the HOME button.

- Select Audio output. If you don't find this option, go to the next step.
- Select Digital audio out.
- Select PCM.
Is optical audio better than HDMI ARC?
Both are better than analog (the red and white cables). Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio. These formats can't get transmitted across optical.Is Bitstream better than uncompressed?
The older, more common bitstream formats (Dolby Digital, DTS) feature lossy compression and are limited to 5.1 channels so uncompressed PCM sound is superior. DTS and Dolby being lossy doesn't mean you are gaining anything by first uncompressing them and then passing over.What is HDMI audio format Bitstream?
HDMI Normal / Bitstream Audio on HDMI or S/PDIF: If you, for example, play a Blu-ray disc with audio encoded in Dolby TrueHD and you select Bitstream, the Blu-ray player will simply stream the Dolby TrueHD track from the Blu-ray disc to the AV Receiver to be decoded.What does audio delay mean on Samsung TV?

If the distance is sufficiently less than 50', within the length of available optical cables, use optical. If not, you'll have to use the RCA cables. If it sounds good, fine. If you get hum or RF rubbish, look for a better system.Are all HDMI cables the same?
Not all HDMI cables are the same. It's true that HDMI is a digital signal, and that as long as the signal is passed cleanly, you won't be able to tell the difference between two different cables. However, digital signals are a pass/fail proposition.Does quality of optical cable matter?
Quality of the actual connection matters most. Then it usually is a matter of length. Short length, then a regular run-of-the-mill plastic fibre is ok. For longer cables you want a glass-fibre with quality connectors to get better s/n-ratio.
