( Digital Audio ) 5.1 surround sound via receiver. Possible?

Is it possible to achieve 5.1 surround sound through an audio receiver using a Coaxial cable? (For Gaming, in particular)
In theory, the coaxial cable should plug into the "Digital Audio out" PC port (Realtex Sound card), and the other end plug into the "Coaxial/Digital Audio in" port of the reciever, which would then produce 5.1 surround sound.
The reason I ask is, after doing much research, it appears that it's a common problem that the method described above is only achieving stereo sound.
My components are...
Realtek sound card (Digital Audio)
Harman/Kardon receiver AVR 247
Coaxial Cable
Any help would be appreciated.

If your PC has an S/PDIF connector, an orange RCA-style connector, then you can connect it to a home stereo. You'll need a cable like this one...
The mystery is in Vista/Reatek settings. To get digital X.1 out, you need to go into Vista Sound Properties, select the default device icon for digital out, go into Properties, and then look at the selections that are available from the Supported Formats tab and the Advanced tab. Make selections for 5.1 and formats that are compatible with your receiver.
If you already have the home stereo and a PC with an S/PDIF port, all you need is the cable. Try it out and have fun. Let us know.
btw... if you have XP, then all this is done through the Realtek software - not through XP.

Audio through my surround sound

I have Apple TV hooked up via HDMI to my TV. I'd like the audio to come through my reciever to provide surround sound. I bought the optical digital audio cable ar Best Buy and plugged it into the eciever and selected the proper input, but no audio throught the surround sound. Any ideas?

Welcome to the Apple Community.
Do you have the TV switched on.
Are you sure you have the receiver set to the correct input.
Have you tried adjusting the Dolby Digital and Audio Out settings.

Mac mini no surround sound via HDMI to TV

I have a MacMINI 2011 which is connected via HDMI cable directly to my Samsung UA55HU8590 TV.
The problem is that the MAC is not delivering a surround sound. If I e.g. watch a movie via iTunes I can only listen in stereo not in DTS or any other dolby sound.
I see in the midi audio setup at the HDMI entry that all my 5.1 settings are greyed out.
I have the latest Yosemite installed.
How can I transfer surround sound via HDMI to my TV?

Try:
Force 5.1 out over HDMI

Will an optical digital audio cable improve the sound when I am viewing content thru Apple TV

I have a 2nd generation Apple TV. When I view content via my Apple TV the sound gets "fuzzy" as I increase the volume on my TV. If i connect Apple TV to my Samsung HDTV with an optical digital audio cable, with the sound quality improve??

people say that if the atv2 dont have a connection to the tv optical is muted
I have a atv1 and been using the optical out with my sony stereo system for ages mute the tv so only 1 audio source and on atv1 it play out the optical even with the tv off
of cause one have to choose the optical input as input source on the receiver

I have surround sound with my LCD TV. Will my new iPad into an HDML connection be able transmit surround sound via Utube, iTunes or whatever?

I have surround sound with my LCD TV. Will my new iPad into HDML connection and Utube, iTunes etc. produce surround sound?

ATV definitely supports AC3 DD 5.1... etc, but definately not through AirPlay, only streamed through the inet.
I also found, in the case of Netflix, that the AC3 is preserved in the highest bandwidth mode but not available in the lowest. (frankly i did not test the intermediate bandwidth)
I was quite pleased with the sound and picture from Netflix.
I am not so patiently waiting for AirPlay to support AC3 DD or DDPlus because I record my home video in %.1 surround (AVCHD) and can preserve it through Final Cut Pro and DVD or Red Laser, but cannot use the intended cable replacement (AirPlay) to play them.
Bummer..
I think/hope if more people request surround sound via AirPlay Apple may then follow through on this otherwise good idea.
FWIW

IPhone 5 audio issues when paired with surround sound via Bluetooth.

iPhone 5 has developed audio issues since ios7 updates when its connected to surround sound system via Bluetooth. Audio jumps and skips in erratic and unpredictable manner on music app and worse on third party apps such as YouTube . Have restored phone from factory settings etc. Have also checked surround sound for fault with Bluetooth; iPhone 4 ios7 works fine, android works fine but newest iPod touch with ios7 appears to have developed same issue as iPhone 5 since ios7 updates. Advise people to check for this issue on their Bluetooth devices and any advice would be appreciated on this issue :)

Hey there Vxas,
It sounds like you are gettings some very unexpected behaviour from the iPhone to your bluetooth surround sound system. I would try the troubleshooting recommended in this article:
iOS: How to troubleshoot Bluetooth connections
http://support.apple.com/kb/TS4562
Check that you are in range of the Bluetooth device with which you are trying to pair your iPhone, iPad, or iPod touch. Most Bluetooth devices have a range of approximately 30 feet.
On your iOS device, tap Settings > Bluetooth and find your device in the list. If your device says Not Connected, tap the name of your device to attempt to connect it.
Tap Settings > Bluetooth and turn Bluetooth off and then on again.
Make sure that your Bluetooth accessory is turned on and fully charged or connected to power.
Restart your iOS device.
Tap Settings > Bluetooth and locate the Bluetooth accessory you are currently connected to or attempting to connect to. Then tap and Forget this Device. Try to pair your Bluetooth accessory again.
Note: You may need to re-enter your Bluetooth accessory PIN if your accessory requires one. Some common PINs are 0000, 1111, and 1234.
Restart your Bluetooth accessory by turning it off and then on again1.
Update your device to the latest version of software. See how to update your iPhone, iPad, or iPod touch.
If your Bluetooth accessory has upgradeable firmware, check to see that you have the latest version1, 2.
Thank you for using Apple Support Communities.
Take care,
Sterling

Surround sound via external sound card

I'm looking to connect my W520 to a tv for watching movies. The video is all set up with a DP to HDMI adapter directly from the laptop to the tv. The sound, however, must pass through a receiver first. The receiver only has RCA inputs - it's quite old. I know the hypothetical setup would definitely work because I have a cable tv set top box connected that way.
What's missing is an external sound card that is:
- compatible with the w520
- capable of outputting 5.1 surround sound
- capable of connecting via RCA, be it through an adapter or not
Can anyone recommend a reliable external sound card for the job?

Have you tried one of these?
dynadock PA3927U-1PRP dynadock U3.0
You can stream 5.1 audio (and the video for that matter as it supports two displays). It also supports USB3.0 as an added perk (the dock itself can be plugged into a usb 3.0 port for best performance). It has one HDMI connection, one DVI-I, and an ethernet connection builtin as well as the usb connections.
PS Missed the bit about you only having RCA connections on your receiver. Lol I would get a new receiver. But then again this device may help you as it does have analog outputs (front,rear and c/sub). You would need to build/find cables though (3.5mm x3 to RCAs).
Btw no SPDIF? If no your receiver must be a pretty old one. Hope its a good one ;-). If you have an coax/optical input then there are also USB devices that will provide 5.1 (maybe even 7.1 nowadays) via the SPDIF connection.

How to enable Surround Sound via Optical line?

Hi, I have been having problems outputting Dolby Digital 5.1 from my Mac to my Panasonic Home Theatre Reciever, When I insert the Optical line with the adaptor, It only gives me the option to send Stereo channels. No options for 5.1/6.1/7.1(Rear/Center)
However, I can use Dolby Pro Logic as another way of Dolby Digital. But I wanted to get actual Dolby Digital 5.1 Surround sound. I don't want to use more space on my MacBook Pro's HDD. Just to encode another movie/TV episode. (a.k.a Family Guy)
Is there a way I can install AC3 on my MBP?
I would appreciate everyone's help!

I Found out the problem. When I was hooking everything up, I kept the t.v. on so I can assign audio inputs with the onscreen display. If the T.V. is left on....only stereo outputted. When I turned the t.v. off and with the airport express plugged into AUX, I was able to switch between surround sound settings.
so the moral of the story is, turn off video devices when you just want sound, especially if they are hooked up to the AVR with HDMI.

Surround Sound via StageVideo in Air for Desktop?

I can't seem to find an obvious answer to this question:
I want to use StageVideo to play h.264 videos with 5.1 AAC audio in full surround via a Mac Mini.
Flash is able to play back video with Surround sound, correct?
What is required to make this work?
Thanks!

Thanks for the answer Alex.
Here is a follow-up: Will a StageWebView within an AIR Desktop app, playing the video via HTML produce the Surround Sound?
Browsers themselves seem to play back the audio fine, just curious before I'm able to test if a StageWebView would produce the same result.
Thanks!

Sound no longer playing through Surround Sound via TV

I have had my Mac Mini for about a year now and recently purchased a new 3D LG TV. Prior to that I had another LG hooked up through it and have a Panasonic surround sound system set up with I believe it's a Gefen digital to analog converter, because unfortunately LG only makes digital and alls that is available is analog through my surround sound. I have always been able to listen to my computer through the surround sound, however, since I purchased this new TV I have not been able to. The sound plays through the TV speaker but will not play through the surround sound yet when I change inputs over to my PS3 or DirecTv I can hear everything else except my computer. This is why I am convinced it is the computer and not the TV. I don't know if I'm missing a setting or something needed to change for this type of TV or what. I am pretty technical when it comes to electronics so I have tried changing all different types of settings and played around trying to fix this but so far no luck so who has an idea or ever heard of this before?

@mndwgz and Lousyfool
Sorry for the delay, however, I was out of town and just getting back to this issue. I'm not 100% positive but I'm pretty sure that it has something to do with the computer settings or something of the sort because like I said prior to me switching tv's it has worked no problem, both of which were connected the same exact way. Both LG tv's only have an optical digital output port on it while my Panasonic surround sound only has an A/V input. To solve this I have a Gefen Digital to Analog converter in between the connection from the TV and the Surround Sound, so my computer is not connected anything in between the computer and HDMI connection to TV. Sound comes out of the TV through the computer but will not bypass through the TV to the Surround Sound. However I know it's not the TV settings because my PS3 regardless of the HDMI input plays sound through and over all my speakers. I have not tried rerunning my computer through the old LG LCD tv connect the surround sound as well to see if it worked because all the way up until I switched to an LED tv, it had. It's weird how this is a problem but have tried switching settings, changing inputs, problemsolving etc. but just don't see how my PS3 is converted through the tv to the converter to the surround sound and my mac mini is not!
Old LCD TV- LG model 42LH30
New LED TV- LG model 47LM6200
Surround Sound- Panasonic model SA-PT950
Converter- Gefen Digital to Analog Converter

Connecting audio channels with surround sound speakers

I have an art project coming up and I was wondering if anyone could help me. I have made a film with a separate .aif sound recording to go along with it. I want the sound to play from different speakers at different points, I have a surround sound system I was hoping to use and thought it might be possible to cut the sound files and somehow place them in different audio channels to link with different speakers. Would this work or is there another way to get the same effect?

I've not personally done it yet, but the theory is sound. I'd expect it to work just fine.
In any event, you'll know for sure once you try.

Surround Sound via HDMI

I've tried just about everything to get Surround Sound out of the MacBook Pro. I'm starting to wonder if it's even possible.
I have a MacBook Pro Mid-2010 (the first model to support Multi-Channel Audio, BTW), and I've been trying to output surround sound to a Vizio 7.1 Surround Sound System (It's got sound quality like you wouldn't believe, if only the speakers weren't so slippery and would stay still.) It's connected to a Vizio HDTV through optical audio, which is connected through an HDMI cable to the MacBook, which is using a Moshi HDMI to Mini DP adapter (It's pretty good quality). I know it's not a problem with the HDTV or the Sound Bar, as Surround Sound works fine with our 3D BluRay, our DTV Box, an HD Upscaling DVD Player, and Windows 7 or 8 PCs, including my Surface Pro 2 (Worst computer in the universe.) The Sound Bar doesn't like PCM very much (sometimes it works), and prefers Dolby.
First, I thought it might be a problem with the TV, so I moved the whole system upstairs to a 720p LG HDTV, which also supports optical surround-sound passthrough from an HDMI source. It still showed as a 2 channel device in MIDI Setup. Then I tried various different settings and restarting and resetting the PRAM. I also tried another, unmarked HDMI to Mini DP adapter that I had in a random box, also to no avail. I thought maybe it only works with a lower display resolution, but no. I even tried using someone else's Retina MacBook Pro, but it had the same problems. Seriously, how does anyone even consider a mac as an audio production platform? This is a serious issue for audio professionals (Not that I'd know, I'm an artist). Anyway, I've even tried a few supposed software solutions, like Perian, which didn't work at all. Someone suggested Soundflower, but I know that doesn't work, because I've actually had it for years. (It's quite useful for recording or redirecting audio.) There's a few tutorials I've seen to solve the problem, but they all stop making sense at the "Set the format to 6 or 8-Channel" part. Obviously, if I can't output Surround Sound, that means that there's no "Format" option that's not labeled "2-channel".
Screenshots: (Ignore the Premiere Pro option, that's just there just it's open in the background)
So basically, what do you do if Mac OS X tells you there's no Surround Sound, and every other device tells you different?

Dam I've done it, ok next thing is where the volumes are grey'd out I would like to increase the volume to the rear speakers.

Audio Out to Surround Sound

Does anyone know of a cable that can convert the audio out on a MacBook Pro to 5.1 surround sound? I have a Logitech G51 speaker system and would like to use it with my computer.

Ok, based on what i know you are not able to purchase any one cord to deliver 5.1 surround sound. What you can do though and rather inexpensively for a entry level ($30-$60 on Amazon) is purchase a USB external sound card. Once you download the drivers for the usb device you can connect the logitec speakers to the sound card and enjoy the 5.1 channel surround sound. Hope this helps!

1st Gen Apple Tv doesnt pass video thru Samsung Surround Sound DVD Receiver

Any ideas?

Surround Sound Via Headphone Sockets With ALSA and/or OSS?

I have a surround sound system that uses the green and black 2.5 milimeter jacks for surround sound. Is it possible to configure ALSA, so that the headphone socket on my laptop produces the front (green) output, and the external microphone socket produces the rear (black) output? Also, is this possible with OSS?

Possible in Alsa, yes. Quite a bit of modification of your .asoundrc. Check this out.
