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."

P2415Q - No display over DVI, HDMI. No menu. Worked perfectly for one month over display port

Reason Line: Dell P2415Q. After one month working perfectly over display port, no display on screen over Display Port or HDMI, no response to menu buttons, backlight and power LED on but no image on screen.
Problem Description
The monitor worked out of the box for one month using the display port to mini display port cable provided with the monitor, which was plugged into my XFX 7970 and 7950 graphics cards. It supported 4K at 60Hz and was exceptional for photos, videos and games. On Wednesday the monitor stopped working, no image or menu is displayed on the monitor. I plugged in my old monitor to help diagnose via DVI from the same graphics card. When I press the power button on the Dell P2415Q monitor, the power LED lights up and the computer detects the monitor (as shown in the windows screen resolution menu). It sets it as a secondary display but the monitor remains black, I can see the power LED and backlight is on. No power saving mode popup appears on the monitor, when I press the menu buttons there is no response from the screen, it remains black. I repeated with a HDMI cable the same issue occurs with no response or image. I repeated and disabled crossfire (which allows the graphics cards to function independently) and tried the second graphics card with no response. I tested the HDMI cable I used on my old LG monitor, it works well. I have tried connecting a laptop over HDMI to the monitor too, with no response from the monitor. I have exhausted all the tests I can think of, I presume I will have to return the monitor for repair or replacement under warranty. A question to the dell rep and community - is there anything else I can try / do to get it working?

No sound with DVI-HDMI

My computer is connected to my TV. I had sound from the TVspeakers through an HDMI-DVI cable on my HP Pavillion with Win 7 64k before. After format, no more sound. Help me!!!

Many of the TVs understand this issue and support the audio thru another port. In my 26" Philips HDTV, I have to select audio input for HDMI port thru AV input or HDMI. If I select AV, then the audio jack from the mac mini needs to be connected to the AV1 input of my TV. So, I purchased a 3.5mm Stereo to Stereo RCA Jack cable and connected the headphone output of mac mini to my TV and voila, I had the audio playing back thru my TV. Other TV brands may have similar implementation, while some may not support computer input at all (this feature is called computer input by Philips).

Lenovo A62 sound via dvi

Hello Everybody,
I want to use a dvi to hdmi cable to transfer graphic and sound via dvi to the tv. Is this possible?
I allready installed realtek high def. audio driver and amd catalyst software suite but no sound over dvi, only over system speaker.
Any idea ?
Regards, feberg
Solved!
Go to Solution.

this is not possible with the integrated GPU. There are certain Nvidia graphics card that allows you to do this. But none of the Lenovo shipped Nvidia graphics card has this ability.

Qosmio G50 No sound over HDMI

*Qosmio G50 No sound over HDMI*
Hi all,
Hopefully anyone recognises the following and would be so kind to help me. I have searched the forum and tried severall of the offered solutions mainly applicable to Vista, but still.
I hooked up my Qosmio G50 to my Philips LCD by HDMI cable. Picture is ok but there is no sound. I tested the cable with a Toshiba Satelite Pro L550 and it works allright. Picture and Sound are working. But that laptop has Intel HDMI audio.
I'm running Windows 7 Home Premium 64 bit. I upgraded by Toshiba update DVD from Vista 64 bit. Sadly I do not know for sure if HDMI audio did work before that. I think so because I did use the laptop for watching a movie on a Panasonic plasma. But I can not remember if that was before or after the upgrade.
Realtek HD Audio device is installed driver version 6.0.1.5923
Realtek HDMI Output is selected als default playback device.
Testing gives me graphical response ( the indicator flashes ) but no audible sound from my tv.
Choosing the other audio device Realtek Digital output changes nothing and I do not believe that this would work anyway.
I have tried removing the device and reinstalling the original drivers. I have tried REaltek drivers from their website.
I have tried changing the view to HDMI only but that does nog change anything either.
One thing that worries me is that under Sound / Realtek HDMI Output / properties / Supported Formats there are no formats present. The Satelite gives me DTS audio and some other. So I am wondering if there should be formats present and if so how can I change this / add any.
Please forgive me if there are errors in the text. I am translating this from a dutch language version of Windows 7.
Please help me. Any suggestions are welcome!

Jeka-?? & PinkPanther thanks for your replies!
The solution for the G30 you mention is not the one for me I am sorry to say. I have tried that one allready. Windows automatically switches on the HDMI audio out when I connect an HDMI cable. Connecting the cable before switching on the TV and laptop is a good thing to try because it eliminates possible problems with the connection. The connection in my case is ok.
At some point I concluded that there must be a softwareproblem of some sort.
I have found the solution over night. Could not sleep anyway. I did not know that the videodrivers are also handling HDMI audio out but in a way it makes sense. I have completely deinstalled the NVIDIA video drivers. After downloading the latest drivers and installing them everything works absolutely fine!

[Solved] A75A-G35 gives no video signal over HDMI, resolution over DVI limited

Hello community,
following problem: I have been using my A75A-G35 board with an A4-3400 Llano APU, the APU has been connected to a 19" BenQ FP91GP monitor via a DVI cable. I got its maximum resolution of 1280x1024 with no issues.
Now I have purchased a 24" Dell U2415 monitor with a maximum resolution of 1920x1200 and wanted to connect it to my computer. However, I got stuck:
1. I get no signal whatsoever using the HDMI output and a HDMI>HDMI cable. I have tested a different computer and connected it to the Dell with the same cable successfully, so the cable and the monitor should be fine.
edit: Disregard the following as the problem with the DVI cable appears also with the other computer. The problem is therefore just the fact that the HDMI output of the board doesn't work!
2. I get a signal with a DVI>DVI cable + DVI>HDMI adapter. I can access the BIOS, the boot manager and see the boot screen, however once the desktop should be displayed the screens turns black and the monitor keeps switching to standby and back on again, the screen staying black all the time, however. But before installing the driver package (for chipset and video, downloaded from the MSI website), I could see the desktop with a resolution of 800x600. Also, if I boot into safe mode, I can see the desktop and increase the resolution up to 1280x1024. Higher resolutions up to 1600x1200 are available, however selecting any of them results in severe screen flickering.
3. If I boot my Linux install, I have almost the same behaviour. I see the boot messages but then the screen turns black when the desktop should appear. However, if I connect the old BenQ monitor to the VGA port, I get a signal on both screens, however both screens have the resolution 1280x1024 and I cannot increase the resolution of the Dell, because if I try to, the screen turns black again. Lower resolutions than 1280x1024 are possible, though. Note that the "second monitor trick" does only work with Linux, with Windows I get only a black screen on both monitors.
As a side note, the DVI cable I'm using is a DVI-D single link, so the maximum resolution it supports is actually exactly the resolution of the Dell, 1920x1200.
Thanks for any hint,
Photon

your welcome!
when you said your problem and the symptoms I thought that board sounded familiar as alot of people when it first came out that we had to explain that to them so I had a look and yes it had the jumpers to switch ports for its digital display display signal to be routed to another port so i thought that was the cause!
have fun with your board now you have it in HDMI mode!

Sound over HDMI works, but laptop sound isn't working after...

Hey,
First, sound over HDMI was not working on my laptop, but when I followed this section of Alsa Wiki it worked.
So I created the ~/.asoundrc file containing:
pcm.!default {
type hw
card 0
device 3
But now, when I unplug my HDMI cable, and want to listen to music using my laptop built-in speakers/jack speakers, it doesn't work anymore, even if I restart Alsa.
In fact, I need to delete the .asoundrc file AND restart Alsa in order to get it work.
Is there a way to make both sound over HDMI, and built-in speakers works automatically depending on if my laptop is/is not connected to my TV ?
Thanks

You need to restore the card and/or device number to those for your laptop speakers, as determined by:
aplay -l
To do this automatically, you will need to use scripts called by udev, as described a little further down.

Strange mac mini sound issue with HDMI cable

I connected my mac mini to my Panasonic 44 inch HDTV with a DVI to HDMI adapter. I didin't get sound through the cable like i expected. Then I connected a 3mm to RCA jacks adapter to the analog HDMI port on the TV and still no sound. Strangely, when i switched resolutions from 1920 X 1080 to 1200 X 720 the sound started working through the audio ports. It works on every resolution except 1920 X 1080. Any ideas why this is so? Or how to fix it?

First off, the DVI standard makes no provision for carrying sound. That is why you didn't hear any sound when making a DVI-to-HDMI connection from your mini to your TV through the adapter. I am assuming there must be a setting on your TV that is snuffing the sound input from the mini rather than the mini not outputing sound at 1920x1080. This would be easy to prove. Just pull the audio minijack connector from the mini's sound out and I'm guessing you will hear sound coming from the mini's speaker.
Is it possible that, on your TV set, you have associated 1920x1080 with an expectation of HDMI input? Maybe the TV is expecting to find digital audio over the HDMI input and somehow that association is only with that one resolution. Then when you drop resolutions it is looking for sound over the analog port instead of over the HDMI port. I'm just guessing here, but it's something you can check.

Mac Mini + DVI- HDMI + Toshiba 42RV530U = black screen

Hi all, I have a new Intel Mac Mini 2GHz and a Toshiba 42RV530U REGZA HDTV that I'm trying to connect, with only a black screen so far.
I believe the DVI output on the Mini is working - I can at least get a picture with a DVI-S-Video cable, but it's obviously lower resolution. The DVI-HDMI cable works - I tried it on our cable box.
When the DVI-HDMI cable is hooked up to the HDMI-1 input on the TV, the "No Signal" warning vanishes, but it's replaced by a black screen. No amount of fiddling with SwitchResX has worked so far.
I've tried coming up with values for SwitchResX based on these numbers from the manual (don't know why the H Freq and V Freq give 2 values for each). I couldn't get exact values, but pretty close. I'd ideally like to get 1080p working.
Name Resolution Vert Freq Horizontal Freq Pixel Clock
480i 720 × 480i 59.940/60Hz 15.734/15.750kHz 27.000/27.027MHz
480p 720 × 480p 59.940/60Hz 31.469/31.500kHz 27.000/27.027MHz
720p 1280 × 720p 59.940/60Hz 44.955/45.000kHz 74.176/74.250MHz
1080i 1920 × 1080i 59.940/60Hz 33.716/33.750kHz 74.176/74.250MHz
1080p 1920 × 1080p 23.976/24Hz 26.973/27.000kHz 74.176/74.250MHz
1080p 1920 × 1080p 59.940/60Hz 67.433/67.500kHz 148.352/148.500MHz
I've also tried repairing permissions, rebooting many times, deleting the windowserver.plist files, zapping the PRAM, etc. SwitchResX identifies the TV as "TSB-TV", which sounds the same as other posts with different Toshiba TVs. I'm able to remote into the Mini via Remote Desktop Connection to play with settings, etc.
Any suggestions? Would a DVI to Component cable work? The TV does have an analog RGB in, but this won't support high def. Thanks for any help!
-Frank

An unforeseen twist... I tried hooking up the Mac Mini to a DVI computer monitor, also with no picture. When I hook up my Powerbook to the Toshiba via the DVI->HDMI cable.... Picture! So, looks like my new (refurbed) Mac Mini has a bad digital video output. Seems a little strange though, since the analog video output on it is working fine.
Off to the Mac store tomorrow.

HDMI doesn't work, but MDP- DVI- HDMI works

Hello!
I just got my new Mac Mini and tried to connect it to my TV (a Samsung LE22S8) over HDMI, but this doesn't work since the TV reports "unsupported resolution" (it's the TV's native resolution of 1680x1050, where I also checked all frequencies using an external program and they are as written in the manual of the TV).
However when I connect the TV over a Mini Display Port to DVI adapter, and then use a DVI to HDMI adapter (so that the TV is still using the HDMI input) it works fine.
So what's the difference between MDP->DVI->HDMI and HDMI->HDMI (all resolution and pixel frequency settings are identical)? What can I do to get the HDMI->HDMI solution working?

It also appears that there is no conversion when HDMI-video is extracted from DVI, only that the pins are shuffled.
If direct DVI works on that port, then HDMI-video with an adapter should work as well. As I mentioned above, VGA is present on DVI-I ports on a separate set of pins, and VGA working or VGA not working has no bearing on your problem.
If a Mini DisplayPort is involved, the most common issue is that the Mini DisplayPort connector is not inserted firmly enough. It has a lot of pins and you have to press hard to seat it.
Other possibilities are that the resolution you selected is beyond the capability of the display device, or that the adapter is bad.
Is this the stock display card, or one you added later, and what model?

Connecting MacBook to Sony Bravia via DVI-HDMI!

Hi I am having major issues with my Macbook connecting to my Sony Bravia KDL-32V4000 I now have 2 different DVI-HDMI leads as well as the Apple Mini-DVI-DVI and still have absolutely no luck.
The Macbook is picking up the Television absolutely no bother at all but there is just nothing at all coming up on the Television its self it doesn't even recognise that I have the computer in the HDMI slot nothing at all just blank!
Any help would be greatly appreciated as it will save me buying more and more cables if this fails to work will have to go with the DVI-VGA I guess would rather fix this though!
Thanks!

I bought a mini-DVI to HDMI and an HDMI to HDMI cable. Once I went into settings for the display, I found that the TV was acting as a second monitor and that it was off to the right of the macbooks own screen. Thus if i moved the mouse to the right it could control the second monitor. You are able to move the screens so that they have the same data on each or use them as two screen with different info on each. Each screen is clearly visible in Spaces and it works a treat.
It is also possible to use the TV as the only screen. The way to do this is to connect up and close the lid on the mac. Once the light on the front starts blinking you can wake it up by using your mighty mouse or external keyboard. once awake, assuming you have chosen the correct HDMI connection from the TV the TV will act as the only monitor at full resolution.
The problem I have, is that I have not been able to get the sound to work. I have used the earphone socket and connected that to external speakers as I cannot seem to get the analogue signal on the TV on anything but an AV channel (not an HDMI channel). Thus the sound works on one channel and the image on another. My TV is a Sony KDL40w5710 - thus if anyone know the solution to getting the sound running through an HDMI channel on my TV it would be appreciated if you could contribute.
Cheers

When I connect my Mac Mini 2011 with Lion to a TV via HDMI and an earphone cable is plugged in, it´s not possible to choose sound out via hdmi, as opposed to connection via minidisplay port. Anybody knows how to fix this?

Was just on the phone with Apple about this.
The solution was as follows for me anyway...
Go to your Finder
Choose the Go Menu
Choose Computer
Choose your Macintosh Hard Drive
Choose your "Library" Folder
Choose the "Preferences" Folder
There should be a folder called "Audio"
Move that whole folder to the trash
Empty the Trash
Restart from the Apple Menu
When you are back up and running;
     Choose System Preferences from the Apple Menu
     Choose Sound
      In the output tab you should now be able to make the HDMI "Sticky"
      Enjoy your sound over HDMI and no more dirty knees or broken backs unplugging the desktop speakers!

Mac Mini on Toshiba Regza Z3030 42" via DVI- HDMI

Hello,
I'm trying to connect a Core2Duo Mac Mini (running 10.4.11) to a 42" Toshiba Regza Z3030 Full-HD TV via a DVI-HDMI cable. The TV does 1920x1080 (both i and p), but when I select 1920x1080 (interlaced) from the display resolution menu in System Preferences, I get a black frame around the image that is twice as large on the right side of the picture than it is on the left or top/bottom sides (so even if I enable overscan, the picture is not acceptable, as it's missing a strip of the desktop on the left, top and bottom sides then).
I'm running the TV on "Exact Scan" mode, which (according to the manual), should display a 1080 signal exactly the way it is received from the source, no stretching or scaling at all.
Incidentally, the grey screen with the Apple logo and the spinning progress indicator fills the screen completely in 1080i, but as soon as the login panel comes up, the picture gets the black bars, so I think it's a MacOS X issue. Can I somehow tell the Mac not to switch the display settings after the booting process is finished, as the image during the boot process is perfect?
Any hints on what I could try?
Thanks in advance,
Georg

Ok, I decided to take some more time and googled for how SwitchResX actually works and what all the settings in the "custom resolution" view mean. I stumbled across a very useful tutorial in this forum thread: http://www.avsforum.com/avs-vb/showthread.php?t=751713
Following these instructions (basically, I just had to play with the "front porch" and "back porch" parameters until the image was perfectly centered), I ended up with a custom resolution in which the image is centered, but still has black bars around it.
Next, I simply turned on "Overscan" in the Display preferences while setting the TV's HDMI port input to "Exact Scan", meaning it will display the image exactly the way it comes over the HDMI port, without extra scaling.
With this combination, I now ended up with a picture that fills the whole screen and has (according to a test image) a "1 to 1" pixel mapping. Also, for some reason, this new resolution that I made myself rather than taking the values off the internet "sticks" between sleep and wake cycles as well!
For some reason, though, the TV only reported that it supports 50Hz vertical sync in 1080p when I used the "Export DDC" function in SwitchResX, even though according to the manual it also does 60Hz (and the default 1920x1080, 60Hz resolution from the Display preferences works as well). Therefore, I was only able to make my custom resolution for 50Hz, as I need the values from the DDC export as a starting point.
I only want to use this Mac Mini/TV combination as a media center for movies and music streaming via iTunes, so I guess it won't make any difference wether I'm running it at 50Hz or 60Hz?
Anyways, I hope this thread might help other people with the same TV who are having similar problems with their Mac Minis.

DVI-HDMI Adapter for hooking up a HDTV...Few problems...

I have a spare 32" Sharp HDTV with HDMI, so I placed this next to my Mac Pro and used a DVI-HDMI adapter. Here are the problems:
With my standard GeForce 7300 GT you cannot use both connectors, as they are too close together - so I could not even test to see whether both DVI outputs can work at the same time. So I have to disconnect my 23" cinema display. Now, the Macpro recognizes the TV - in the display preferences - but the resolutions are not good - the only one that works is 1280x720. Other resolutions listed, ie, 1344x756 and higher are listed as interlaced and all cause flicker. This means I do not see the OSX top menus.
I wish to be able to show clients samples of edited movie clips on a HDTV both in FCP and standalone QT. I doubt that appleTV is the answer, as this only works in iTunes - plus, my Mac is next to my TV anyway.
Any thoughts on making this work better? I am trying to not have to buy a new video card. Maybe the Black Magic Intensity card for HDMI output is the answer?

I can live with the lower resolution - the TV is actually 1366 x 768, but the most annoying is not being able to use both DVD connectors on the card at the same time - they are too close together, how stupid is that?
Ideally, I would like to see both the cinema display and the HDTV running at the same time - or least not having to manually switch over the adapter at the rear.
I see no way around this, unless I change video cards but for $250 I can get the Black Magic HDMI card which outputs DV via HDMI to HDMI.

Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.
