Thank you for that video. I've done my own research to learn most of that, but this was clearer. Also makes me realise I should have the BD secondary audio set to on, on my 4k player.
You can always, when sending PCM, use an upmixer (DSU, DTS Neural:X or Auro 3D) in the processor/reciever to upmix the 7.1 PCM stream to use all the speakers. Even the height speakers.
@keetvhdlimited962”sounds better” is totally subjective. Is it louder overall? Sound coming out of all speakers? This is not a good idea because you’re sending an “uncompressed stereo” codec to your receiver and you’re either getting Dolby 2.1 surround or a stereo mix going to all speakers.
I am not sure if there is a difference between PCM and LPCM but PS5 has 3 options: LPCM(uncompressed), DTS(compressed), DOLBY(compressed). Which is why I use LPCM with Denon x3600h
@KTV HD It’s the arctic nova pro , I have no clue about 5.1 and these values. I see people saying use linear pcm or Dolby for ps5 . I use Dolby because someone from the astro stuff commented on Reddit that linear is only sterio
He is referring to gaming only. For blu ray playback it’s either Bitstream or PCM. The reason is because sony cannot do Atmos/DTS X in video games. It can only do that in movie playback. That’s why the two have different settings.
Wrong the audio on the disc is already compressed if it wasn’t it be way to big. LPCM is uncompressed meaning it dose nothing to the audio it dosnt mean the audio track itself isn’t compressed it still is. If your using a high end soundbar or AVR you always want to pick bitstream the amplifier in the soundbar or AVR boosts the audio if you pick LPCM the player or console whatever the source is will just convert to it to LPCM it’s best to let the audio equipment do the decoding.
Here’s the simple answer do you want your audio equipment to do the sound decoding or do you want your player to do the sound decoding and have your audio equipment just play it. Me personally let your audio equipment do the decoding that’s why you have the setup right. If you’re just using the tv speakers or a cheap soundbar go with LPCM.
I'm playing bluray movie through PlayStation 3, PCM output to AVR sound better than bitstream, if output bitstream, sound very low, especially the center speaker.
The part about BD secondary audio being set to on is throwing me. In the manual for my UB820 and a Dolby home guide they both state that to get full Atmos and DTS X, both should be set to bitstream and the secondary audio set to off. They both state this setting on players is for an alternative audio track on the disc if some of your equipment doesn’t support the primary audio track. Not that this setting allows for a separate overhead mix to play for full Atmos or DTS X. Some clarification on this would help, thank you.
I'm sure it depends on model, brand, and firmware updates. What Brian states in the video is a generalized settings, however, your equipment may differ. Try out all the settings on and off and see what you like best. At the end of the day, you decide what sounds best on your system, not strangers on TH-cam.
I've been researching PCM vs Bitstream for the past several days. Every discussion, every single resource has stated (in no uncertain terms) that PCM can only send 2 channel audio. Now this guy says PCM can send up to a max of 7.1 channels. Every discussion I find is contradictory to the previous discussions. I'm pulling my hair out. Good grief.
Can you show me a link please? I have NEVER seen any documentation ever that says PCM can only 2 channels, furthermore, if that was the case why hasn’t anybody in this comment section called me out for putting up false info.
@Movie University ~ You raise a very valid point. I've never seen so much contradictory information on any topic. I'll get you some links later tonight for sure.

I have connected my Sony bravia tv to Cambridge CXA80 amp using an optical cable and playing the audio in 2 JM Lab cobalt 816 speakers. Now i have got 3 options in my Sony tv for audio output, 1.

hi. i have a sony 5.1 surround system that supports only dolby digital & dts & lpcm connected to sony tv via arc. i use the surround when playing 4k movies on samsung k8500 4k player. my question is should i set the audio in the tv & dvd player to pcm or bitstream unprocessed? i heared that bitstream is used only for high end surround systems like those who support atmos for example. need ur advice please.
Listen to what Brian says carefully. Both have the same sound quality. However, Bitstream can play spatial sound like Atmos and PCM can’t. It’s a matter of how the sound is being decoded from the source, not of quality.
@@MovieUniversity Could you clarify that though? Dolby is a compression technology and is compressed audio, is it not so? I have heard many different calls on it.
When i choose PCM via Spdif i only get 2 channel emulation to all my speakers... When i choose bitstreming i get real 5.1 output for my movies but only on Dolby digital formats if i run a movie with DTS audio i get no sound... PCM works with all audios formats but only with 2 ch emulation! How can i output real 5.1 using PCM setting ? Can PCM output 5.1 or only support 2 ch output ? I am confused !
Jesus Christ, why are you still calling it Spdif? It’s an optical cable and that is extremely outdated tech. PCM though optical is always going to be downgraded to 2 channel. The bandwidth of optical can only support compressed audio like Dolby Digital 5.1 or DTS. If you’re going to stick with optical cables, you have to stay on bitstream if you want surround sound.
Are you using optical out from your tv you need to plug your player or consoles directly into your audio equipment not the tv and optical can’t pass the HD audio formats only HDMI can. Optical only supports Dolby Digital and DTS not the HD audio.
I do have a question about this... I own a Nintendo switch... and noticed something strange.... if I set my sound from pass through to digital. After a second or 2 of not navigating the switch menu. Or game auido. The auido will cut out when resuming. But if I set it to pass through everything is fine!!!! Why is this? And why does the auido cut under bitstream?
I couldn't tell you. Sounds like that's more of a programming thing internal to the Switch. Does it affect the syncing of the audio between the speaker(s) and TV?
I have Nvidia shield streaming device..plus Denon avr..my question..In my NS settings their is a setting in my Audio that’s telling me that I can upmix stereo to 5.1 pcm..not sure if I should! I have a 5.2.2 speaker setup..if anyone can’t help it would be appreciated!, thx
My samsung tv have 2 format while playing netflix (atmos movies). Automatic and pcm.

It has no problems if choose pcm format, but the sound wasnt so good, no dolby atmos. Hows that so, and how to fix this? It makes me frustrated
It is not possible to play Dolby Atmos using PCM. You MUST put your setting to auto to utilize the bitstream format. Are you streaming Netflix through the TV or another device?

When I watch a UHD disc on my PS5 that’s connected to my LG CX (which cant decode DTS) and then to my soundbar (sonos arc) which is connected through HDMI eArc to my CX, it reads DTS content as ‘Multichannel PCM 5.1/7.1’ Am i still getting the same audio quality (bitrate) as if it could decode DTS?
I don't think so, but I could be wrong. Because the LG TV isn't an audio/receiver unit it doesn't have the ability to unpack or pass on the signal. You'd need to hook the PS up separately. One cable going to the sound bar and another going to the TV.
@@MovieUniversity hmm, my Sonos App shows it as MPCM 7.1 when I put a DTS X UHD disc in. As long as there’s not such a thing as lossy PCM, I might be getting lossless. Hope so anyway….
I’ve been having HORRIBKE audio delay with my OG PS4 and Den-in AVR-x7200wa. It’s most noticeable with GT7. Of course I’m using H-DMI and not optical. I decided to switch it to PCM from Dolby, and the delay during shifting, going over rumble strips or kerbs. Contact with walls or other cars results in about 1/4 of a second delay!!!! Switching to PCM corrected the delay. However, tone is different and I have to readjust the output of all 11 speaker for this particular input. GT7 has stereo or “7.1 surround. I don’t know if it is DTS or Dolby or Sony’s own code. I’m guessing it’s a SONY format. For some reason, both DTS and Dolby are causing a horrible delay which makes the audio from the PS4 to be ahead of the AVR output. I cannot use the audio delay on the TV or AVR. It makes the delay worse.
If you’re running the ps4 to your tv and the tv arc to your receiver that’s most likely the delay. Either way unfortunately when you sent a pcm signal to you receiver it just downgraded you to “uncompressed” stereo or some other 5.1 simulation. I hate PCM.
You have to run the HDMI from your PS4 directly into the AVR or Soundbar first then run a second HDMI out from the AVR or Soundbar to the tv. You’re getting a delay from the tv. If you do it this way then you can run everything in bitstream with no problems

You cannot get Atmos or DTS:X with PCM because of the technological limits. Only possible through bitstream. No matter your HDMI cable or what you are putting out from your A/V receiver.
