If I remember correctly DTS bitstream is actually slightly higher bandwidth compared to Dolby Bitstream. DD and DTS bitrate is way batter than any raw sound from video games. Where do you mean to set HDMI as main output? In terms of sound quality, whether you set the Blu-ray Disc player's HDMI audio output PCM or bitstream doesn't matter. TV is set to bitstream via hdmi. My set up is ps4 pro connected to TV and TV to the speakers via ARC HDMI. Random, but you know whats weird, Dark Soul 3 and Doom(Bethesda games) have less normalization in them(louder at much much lower volumes) I don't know why but it's something I've noticed. Use PCM if you are just going to use plain TV speakers. Bitstream means don't touch the source and send signal as is. Both Dolby and DTS bitstreams should work. I'm using PCM also on my PS4. Not lossless. As for bitstream versus LPCM there is really no difference. While lossess is actually better quality, some people can not hear the quality difference and actually prefer Dolby Digital because it kind of over samples everything more than it should. Compatibility with devices and supported frequencies are bigger factors to consider than sound and transmission when choosing between PCM and bitstream. Curiosamente, a maioria das pessoas não tem uma idéia clara de fazer uma escolha entre PCM e Bitstream. However, here is what happens when you choose either setting. I don't know if you ever got this figured out, but here is the reason. Pcm is the more "pure" unencoded and bitstream is encoded. The reason bitstream sounds better to you may be because setting it to PCM forces the sound to stereo on the PS4 side. My speakers say they support DTS and Dolby Digital. PS4 is connected to the TV via HDMI and the 4.1 Samsung Soundbar system is connected directly to the TV via Optical cable. - Driveclub has a proper 7.1 mix but it doesnt send much engine noise to the rear speakers only tire squel, gravel and collision sounds. 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. Tutorial sobre cómo configurar el audio de manera correcta tu Ps4 o Ps4 Pro para escuchar en Receiver o Barra de Sonido So i set the PS4 to Bitstream (DTS) and let my receiver upmix the sound to 7.1 which works quite well. Dolby Digital lub DTS. Use PCM if you are just going to use plain TV speakers.

Same situation. Bitstream to prawie to samo, ale dotyczy innych formatów dźwięku, takich jak np. Bitstream oznacza wypuszczenie dźwięku w postaci źródłowej z płyty.Wszystkie kodeki wyszczególnione powyżej (DTS/Dolby itd.) W surroundach nie było dźwięku, przełączyłem na Linear PCM w PS3 i jest już dźwięk. I think I have the same set up as you. I got it wrong. So I have two questions – QUESTION ONE: does anyone know why this could possibly be happening? Pytanie, jak to możliwe? Set HDMI as your main output and the LPCM will be multi-channel. Wut? This will ensure that you are getting the properly coded audio from what ever game you are playing. Im setup similar and the max quality I can get to pass through ARC is Dolby Digital+ (which isn't a PS4 output option). Yeah in theory but for some reason recent Yamaha receivers won't do this. I had the same issue in the game Until Dawn but have never had it another game. But using ARC HDMI forces me to use HDMI CEC, which I hate because it makes the TV automatically switch to other sources when, say, I turn the PS4 off. Nie potrafię nigdzie znależć czy ten soundbar bez problemu radzi (dekoduje) sobie z dźwiękiem przesyłanym w formacie PCM. Linear PCM (over HDMI) is the 'native' format of the sound generated by games. 3. Press J to jump to the feed. Et je ne sais pas lequel utiliser. D'après ce que j'ai compris, le PCM est de meilleure qualité, pas compressé, sauf que, lorsque je passe en bitstream, mon ampli reçois bien des signaux DD, DTS, DTS HD ou DD TrueHD, et ce jusqu'en 7.1, mais en lisant les infos sur le net, d'après les différents avis, ce ne serait pas un vrai 7.1 ou alors en qualité limitée. Otherwise use Bitstream for surround sound decode for your setup. 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. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. So, bottom line is, with the PS3 set the audio output to "Linear" when using an HDMI cable. Playback the disc and while it's playing, press the It might depend on what your tv can pass along. Brb, changing my configuration. I believe Bitstream allows raw decode of audio data while PCM uses some form of transformation/compression to decode. - GTA V seems to "only" have a 5.1 mix even when set to lpcm. 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. In the Dolby/dts bitstream the sound bar will do the decode so you can get all the channels. So when set to BITSREAM you are actually not getting full HD sound. It's a real pain. Je m’explique, on me propose PCM ou BitStream Dolby. Press question mark to learn the rest of the keyboard shortcuts. Well, it's just a data file you can call it PCM data file but when it's just referred to as PCM misunderstandings happen (and the thing you have to understand is that going from analog to digital isn't 1 to 1, going from digital to analog is though so in a broad general sense PCM is … Not really, 1, DTS and PCM both are same for games only DOLBY DIGITAL is bad(lower quality) and the only difference is the low freq/ SUB. 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 … I have reviewed many posts in the A/V forums and other areas that don't seem to give a definitive answer. Is Bitstream Dolby doing some sort of post-processing "simulation" to place sounds through my speakers, and is Linear PCM playing the purest form of audio, the way the games are supposed to be playing their respective sound? Częstotliwość próbkowania takiego zapisu wynosi 44.100Hz. Press question mark to learn the rest of the keyboard shortcuts. The TV can be set to output DD when using the TV's built in apps for viewing, and there is no audio delay to the soundbar. Setup is a bit odd, so I was wondering which one I should stick with. I've got a Samsung 4k TV and had to rearrange everything just like you to have the 4k HDR signal. Output audio via HDMI, and ensure that the "Audio Format (Priority)" is set to "Bitstream (Dolby)." Bitstream unprocessed. Linear PCM is the PS4 decoding the audio stream. nothing else why? So after trying to figure out why this was suddenly happening (tried turning receiver on/off, tried turning PS4 on/off, tried turning TV on/off, problem still pops up), I tried switching the audio to Linear PCM, and the problem goes away. New comments cannot be posted and votes cannot be cast. Again, that PCM signal will be downmixed to a 2.0 stereo signal. 2. Dialogue on some movies is really low with Linear PCM. If you want uncompressed audio the ps4 would need to run through the AVR. Some of them aren’t aware of what Bitstream and PCM are and why should they choose one over the other. Bitstream for gaming is limited to Dolby Digital or DTS on the PS4. PCM will decode the 7.1 or 5.1 core only and bypass the Atmos encoding. Doesn't matter if I bypass the the tv. The largest PlayStation 4 community on the internet. Bitstream re-encoded for Dolby/DTS will almost certainly do the same thing and give you just the core.

Some argue that when PCM is selected, the PS4 encodes the audio and when Bitstream is selected, the PS4 sends raw audio to your receiver so that your receiver can encode it. No idea why it might be suddently failing but I wouldn't worry about it and just use Linear PCM as your system supports it. Make sure you have set HDMI as your primary output or else you'll just get stereo through it - which might be why you think that the surround effect has degraded.

In the case of the Sony® Playstation® platform, both the PS3™* and PS4™ are capable of performing bitstream pass-through of Dolby formats when content is played back from a Blu-Ray disc™. I believe Bitstream allows raw decode of audio data while PCM uses some form of transformation/compression to decode. 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. Bitstream and PCM are capable of producing the same audio quality, and the only difference is how your setup decodes the compressed file. Procedure.
