Audio over standard DVI HDMI?

What are the audio capabilities with the 1st 4 generations of MacBook Pros with standard full size DVI outputs when using a DVI to HDMI adapter?
I know that the mini display and thunderbolt ports support full quality 7.1 audio at 24bit 96KHz over HDMI (plug and play right out of the box to a surround receiver). What about the DVI machines? Can you at least get stereo audio thru the DVI port for basic TV/movie watching? Or is audio over HDMI only available starting on the 5th generation MacBook Pros?

Ehych is very correct.
On your $300 switch box, here is *one from MonoPrice* that is only $43!
I've purchased several cables & switch boxes from them - VERY good quality, price & shipping.

Sound over DVI- HDMI

So, until yesterday, I actually believed that this was not possible, but I updated BootCamp to 4.0 and I noticed that when I was using my external display with a MDP -> DVI -> HDMI, there was sound and video coming through it.
My question is, how do I send audio and video using the same combination using Mac OS X Lion ? Apparantly it only works in Windows.
Thanks!

And from Wikipedia:
"Features specific to HDMI, such as remote-control, audio transport, xvYCC, and deep-color, are not usable in devices that only support DVI signalling. However, many devices can output HDMI over a DVI output (examples: ATI 3000-series and NVIDIA GTX 200-series video cards),[7] and some multimedia displays accept HDMI (including audio) over a DVI input. Exact capabilities vary from product to product."

Not sure that I have selected the correct forum. Hope my questions are clearly stated.
Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter. TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices). It does not show Mail or Safari menus. System preferences' display "gathered" the Samsung and chose its resolution. I did not find a way to select the Samsung as my display.
In addition to having old hardware, we have Verizon FIOS providing internet and TV access. Is there any way to make this work for us? We would like to stream video (Netflix) and view shows from the Web. Do we need Apple TV to do this? Or is it not possible with our old iMac? My husband thinks that our Airport could be a factor.
Thank you

Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
There are, actually, many alternatives to choose from than just from a Mac.
You need to have or invest in a WiFi capable router for all of these examples.
Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
If you have a older Mac, like I have noticed many users do, then you have other options.
If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time, you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

Switched from DVI to HDMI, I can't get audio over analog! [SOLVED]

I want to use my onboard audio instead of the HDMI ATI audio (I'm using catalyst if that helps), but it seems to have all but disappeared as an option. For example, KMix now only allows me to switch mixers between my webcam mic, HDA ATI SB, and HD-Audio Generic (S/PDIF). In the Phonon audio setup, if I test hw:1,0, sound comes out of my headphones like it should, so I put it on top of each list in Playback, and HDA ATI SB below that since that works too... but why, my headphones are hooked up to the motherboard, not the graphics card? I'm just so confused right now.
EDIT: Solution is to set up the default sound card as specified here.

No screensaver or sleep when outputting audio over HDMI

I am using a Mac Mini i5 2.5 running 10.8.2. This is a new setup and I have tested it with a standard computer monitor and it works fine, however when I implement it in my home theater setup running into a Pioneer VSX-1325 receiver, which I use for my video and audio switching the screen saver will not turn on once I have played any audio over the HDMI (iTunes, Netflix... etc). From a cold boot the screen saver will boot up, until I trigger any sustained audio (non-system sounds) through the HDMI connection... This includes web based audio as well. Has anyone else experienced this? For this is a major issue as this display is connected to a plasma TV and I can not rely on my wife to always use a hot corner. I do not want any image persistence or burn-in on my display. I should add the the screensaver function will resume after a period of time when there is no audio being output.

Apparently this was an issue in Lion as well. Thread below, but can Apple fix this ASAP before I have a Plasma with burn-in?

H61M-P31 (G3) Audio over HDMI

Hello
i m trying to make a HTPC with H61M-P31 with i3-2125. i m not able to setup with onboard audio over on HDMI cable using onboard disply DVI port. within window 7 i do see my Sony TV but there is no way for me to selet the TV as a audio device inside Volume control option. is it something that i need to set in bios ? what is PEG and IGD stand for ? thx so much for any type of help

What a surprise to see you on here, micgo.
IGD = Integrated Graphics Device
PEG = PCI Express Graphics
DVI provides display signal only but no audio therefore you may need to use a video card with HDMI output to accomplish your goal.

USB Dock 3.0 Audio through DVI-HDMI cable?

Hey there!
I currently own the yoga 2 pro and I am looking for a suitable dock. One thing that prevented me from ordering the usb 3.0 dock was that I am not sure whether with a DVI to HDMI cable I am able to get audio from my laptop to a TV.
For better understanding: Laptop -> USB 3.0 -> USB 3.0 Dock -> DVI -> HDMI -> TV
I asked my local retailer and they said it isn't possible but I am not sure whether they tested my method. They said I'll be needing a seperate audio jack cable -.- ugly... with my old 460 GTX I was able to transmit sound with the same DVI/HDMI cable
Can anyone who owns the USB 3.0 dock confirm that audio through DVI-HDMI cable to a TV is working / not working?
Any help is appreciated!
Greetings

DVI won't carry audio on the ThinkPad USB 3.0 dock.

785GT-E63 - Audio over HDMI

Hello All,
I couldn't find this info anywhere, and am hoping that folks here can assist me.
Does this board support audio over HDMI?
I would like to use this board in HTPC setup.
Thank You!!!

Quote from: Fredrik on 20-April-10, 05:16:50
Hello!
Speaking of info. - Please describe your system in some detail, and do not forget to mention the specs of your PSU. There is a sticker on the PSU box.
Generally HDMI transports sound, yes.
Thanks for the reply.
My set-up is pretty simple.
Besides the new MB and CPU (which i got at a great deal on $115 for both) all the components are being recycled from other PCs.
MSI - 785GT-E63
Athlon II 630
2x512MB of DDR2 Ram
Thermaltake TR2 430W PSU
nMEDIAPC HTPC Case 6000B
Windows 7 Ultimate
1.5TB Segate HDD
2TB Hitachi HDD
Video capture card (don't know the specs)
I do not have a dedicated video card, and for my purposes i don't think i need one.
I would like this HTPC to output audio to a 5.1 channel system powered by Onkyo TX-SR507 Receiver through HDMI
This will be used to watch 720/1080p video downloads, brows pictures, basic online browsing and maybe convert some of my old family VHS videos.

P7NGM-digital : audio over HDMI ?

Hello,
I read elsewhere that for this board, P7NGM-digital, audio over HDMI was not possible ?
Is it true ?
As it is not working for me.

Problem solved. Uninstalled all windows updates and display drivers. Reinstalled windows updates in groups of no more than 5 at a time, restarting after each group. Installed latest Intel display driver, restarted. Works like a charm now.

Simultaneous audio over HDMI and line out optical

Anyone know if this is possible on the new mini?
I currently use an AppleTV with HDMI to TV and optical digital to my older surround processor which does not accept HDMI.
AppleTV is useful in that it outputs audio simultaneously over all audio connections - I suspect new Mac Mini might only allow single audio output at a time.

...I assume by saying this you're implying you can deliver video over HDMI but audio over toslink through the line out i.e. audio out to non-HDMI destinations is not automatically disabled by an active HDMI connection...
Correct. You choose your audio output in the sound control panel (or Option-click on the sound icon in toolbar).
That's ideal then really.
...- that would then allow HDMI video to TV, toslink to AV processor, and analogue audio from AV processor to TV analogue audio in to use when you only need the audio via TV speakers...
I doubt the TV will take an analog audio in at the same time as HDMI video in. It likely only accepts analog audio on inputs that are also analog for video (component, s-video, composite).
You're right, unlilely to be configurable for HDMI, there might be the odd set that allowed something like this but in general most wouldn't.
...A small utility/script might be feasible to toggle between the two on the Mini...
Yes, entirely possible.
Another option would be to do what I do: Disable the TV speakers and use the receiver for all sound. Since TV speakers suck, this is a great option. I haven't used built-in TV speakers for at least 15 years.
I generally do that too, just sometimes for late night listening when others are in bed I switch to the TV speakers, but actually it'd be far easier with no TV audio as you'd not run into those instances when both TV and hi-fi are outputting and messing up the audio effect entirely.

Z68MA-ED55 (B3) - Realtek HD Audio over HDMI

Does anyone know if the motherboard Z68MA-ED55 (B3) is able to get HD Audio out from the HDMI connection?
When I installed the Realtek HD codec I only see listed two digital outs: optical and atapi. (which I don't know what atapi is for)
I think my motherboard need bios updates as mine is in version A1, and the latest A4 seems to fix some audio tables (which I don't know what it means neither..
Anyone has HD audio over HDMI for this board or advice about what to try?
thanks
Update:
Seems my board should support HDMI HD Audio out..
From MSI board document:
Chip integrated by Realtek® ALC892
Download the manual at: http://www.msi.com/product/mb/Z68MA-ED55--B3-.html#?div=Manual

Any luck getting HD audio to work over HDMI?

[SOLVED] Audio over HDMI stopped working? (Intel/i915)

My audio over HDMI was working fine until recently and I can't figure out what's stopped it from working... My configs haven't changed and aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav gives no errors, but no sound can be heard. There are no errors/messages in dmesg either.
My graphics card uses the Intel i915 chipset (Asus laptop).

Yeah I checked and everything is fine... this is really weird!
I've tested audio over HDMI on windows, so I know it's not the cable/HDMI port. I've looked through my pacman.log (I tend to update daily) and the only thing I can see which could affect it is a kernel update and intel-dri. I tried downgrading those and re-tested, to no avail.
I also installed pulseaudio and pulseaudio-alsa before it stopped working. This could have broken it, but I've since uninstalled them and replaced /etc/asound.conf with my original, so that rules those out; unless there is something else that pulse could have broken?
Cheers

No audio over HDMI

So, I generally use Windows via Bootcamp on my 2012 Macbook Pro (15"), and I frequently hook it up to my projector and media center via an HDMI cable. Everything was working perfectly up until three days ago, when suddenly the laptop wouldn't send audio over HDMI. On the Windows side, I spent a couple days doing everything the internet said I should try (reinstalling drivers, rolling back drivers and updates, managine audio output devices, etc.) and never got anything. My graphics driver could see the HDMI device and said that there should be an HDMI device on my sound control, but it never showed up.
I figured it was a problem with Windows, so I jumped over to the Mac side, where I'm running Mavericks. Just like the Windows side, video works flawlessly but there's no audio output. In Preferences, under "Sound" and "Output", I only see the speakers of my laptop and one AirPlay-compatible device that's set up in the room. Headphones work great. But there's no way to send audio over HDMI.
Just to be safe, I installed a fresh version of Windows and a fresh version of Mavericks, and I'm still not getting anything. Is there something that I'm missing? Because right now it feels like it's a hardware issue, but there's no reason that it should be. And I'm confused about why I still have perfect HDMI video if it is a hardware issue.
Any help on the issue would be greatly appreciated. Thanks!

I should mention, by the way, that I ruled out issues with my HDMI cable or other hardware. I have tried multiple cables with the same results, and my roommates can all send audio over HDMI without problems.

Ok, rc7 is out. Dave Airlie disabled HDMI Audio on rv710,rv730.
Dave Airlie (9):
drm/radeon/kms: fix incorrect logic in DP vs eDP connector checking.
drm/radeon/kms: use active device to pick connector for encoder
drm/kms/radeon: pick digitial encoders smarter. (v3)
drm/radeon/kms: release agp on error.
drm/radeon/kms: move radeon KMS on/off switch out of staging.
drm/radeon/kms: disable HDMI audio for now on rv710/rv730
drm/radeon/kms: make initial state of load detect property correct.
drm/radeon/kms: rs400/480 MC setup is different than r300.
drm/radeon/kms: fix r300 vram width calculations
EDIT: Further more, Jerome Glisse talked about future radeon development [1]
Coming up in the Radeon DRM for the Linux 2.6.34 kernel (or releases thereafter) is support for un-mappable VRAM, support for Evergreen GPUs (Radeon HD 5000 "R800" series), use of the Linux power management API for better suspend-and-resume support, better DRM power management, HDMI audio for R700/800 graphics processors, and improved GPU lock-up recording.
Therefore, Audio over HDMI is expected for 2.6.34+!

10.7.1 Audio over HDMI Problem

Hi All,
Here is a breif history of my problems with audio over HDMI. From 10.6.3 to 10.6.7 everything was working great. I have a mid 2010 i7 iMac hooked up via HDMI to a Marantz receiver which is in turn hooked up to a Panny TV. Everything worked as it should, audio went out to the receiver and video to the TV. Then the upgrade to 10.6.8 began the trouble. On the Marantz, I have a visual representation of the audio input. The unit showed that the audio was intermittently "flashing out". That was confirmed while listening to the output of the iMac via the Marantz. The image to the Panny was solid. I tried a variety of fixes (grabbing system files from 10.6.7, PRAM reset, etc.) all to no avail. So I reverted back to 10.6.7. Recently I tried again. Upgraded to 10.6.8 and applied the supplimental update that was supposed to fix the audio over HDMI issue. No good there either. I got the same audio dropping out problem. So I figured I'd go all out and try to upgrade to Lion. The upgrade went smoothly but the problem has morphed a bit. Now when the Marantz is on the iMac input, the iMac doesn't output audio or video ver HDMI. The moment I switch to another input on the Marantz (DVD for example) the iMac senses a switch and outputs audio and video. (At least that is what Display and Sound preferences indicate, as I'm not on the correct input on the receiver, I have no way to verify that anything is actually happening). So I'm back to square one. Do I downgrade back to 10.6.7? Any opinions or similar experiences out there? TIA!!

If anyone's curious, I seemed to have solved the problem the other night. I simply switched the HDMI input on the receiver. Previously it was going into the "game" HDMI input, and I switched it to the "DVD" HDMI input. I'm not really sure why that made a difference. As I mentioned before, all was fine under 10.6.7. Perhaps under 10.6.8 and later, Apple changed the HDCP and the Marantz can only make sense out of it on a "traditional video input" (ie DVD). That's the only explanation I can come up with. Oh well, all's well that end's well I guess.
Thanks.
