Display port sound

[Rem4rk4ble]

I'm wondering if I hook up my pc to my AV receiver with a displayport (pc) into an hdmi (receiver) will i be able to get 7.1 sound, and are there any circumstances like specific gpus?

Yes Display Port support multi audio channels however a GPU only has output slots no input. So you cant get a signal from an AV reciever to the GPU and output in on the PC.
If you want the PC to output 7.1 this is nor problem

@Goos Kaboose:
I would highly recommend getting an audio card of some kind. Creative makes decent audio cards, both internal and external, that hooks up to your receiver. I have a 5.1 Surround Sound home theater system that uses Fiberoptic SP/DIF and my Creative Soundblaster Omni hooks into it with great results.

Display port can output audio on multiple channels for sure, but you won't get the same quality that would come with an audio card.

that's BS... the bandwidth is the same. and in the end it depends on the reciever. and the soudncard cant take an audio signal from the AV reciever.

Just use DisplayPort for your actual Display, then you could transfer audio from GPU over to the A/V Receiver via the HDMI. Just change the Audio Output in Windows (Nvidia control panel) so that it's coming from the hdmi, not the dp.

The OP wants audio playback....why are you confusing the two?

Uh, DisplayPort has enough bandwidth for super high quality, just like HDMI... more bandwidth than TOSLINK (Optical) can handle. TOSLINK compresses anything that is more than 2 channels. DisplayPort and HDMI are able to deliver over 2 channels without compression.

NVIDIA only allows 2 chanael audio...the OP wants 7.1...

We need as in poor audio, which is true. All those DP or HDMI will do is 16bit / 48Khz ~ LOL

Yes, but the device outputing the playback is a VIDEO card...and NVIDIA only allows 2.0 channel output...regardless of quality, the OP will NOT be geting the 7.1 surround sound they desire.

nvidia isnt a soundcard, nvidia outputs the sound about the GPU which will be done through windows in the end and Windows is capable of 7.1 which you should know as a certfieid Microsoft technician...

TOSLink is what we need to use,...I am not the one suggesting to use the video card....I am the one suggesating the OP get an audio card to use to for output to the reciever.

No kidding it isn't a sound card....you were the one who suggested they not use a sound card...and use the video card's display port adapted through HDMI in stead.

you didnt understood the irony.... Displayport is both 16 and 24 bit capably and 32-196kHz...more then capable to do this job without dedicated soundcard as the AV-Receiever will convert the sound not the GPU.

[Bad 💀 Motha]

GPUs all have the Audio Codec is right on the GPU itself.
No they never will output more than 2-channels. When it comes to using HDMI/DP from your GPU. Yes the cables support much more, when used with a TV, Receiver, and various hardware of that sort. That is now how it will work on PC.

Yes...and only 2 channels availible through that option...go test it yourself.....

I know it is, but it is a crappy one. Seriously...why would anyone in their right minds use a GPU's 2 cahnel audio output for a 7.1 surround sound system?

Not sure where you are getting your information. A quick internet search and you will see that HDMI and DisplayPort are more than capable of 32 bit and 192khz.

Optical cannot send more than 2 channels uncompressed. For stereo, optical is fine, but when it comes to surround (multi-channel), it just cannot perform without compression.

The only way to get features, such as Dolby TrueHD or DTS HD, is with HDMI. Anyone with a decent surround setup will use HDMI over optical.

Simple fact, HDMI and DisplayPort can passthrough higher resolution audio.
