Thunderbolt to HDMI audio issues

I apologize in advance if this has already been asked in some way that I didn't see in my previous searches for answers.
Why is it telling me this? I have been pushing audio through perfectly fine, then yesterday it started to display this and was no longer pushing anything. Anyone know how to fix? I have changed nothing on my physical display or my prferences to bring about this change.

I posted a picture on there, but it appears it didn't go through. I shall attempt to get it up again.

Thunderbolt to hdmi audio inconsistent

I have the macbook pro 2010 i7 2.66G 15" with 8g ram osx 10.9.2
connect the thunderbolt to hdmi adapter, video is perfect, but the audio quality is inconsistent,
the way I set it up,
turn on the samsung tv to hdmi input source
turn on the macbook pro
set the sound output to samsung hdmi
play the video in vlc, quicktime or youtube.
sometime it is good, but when I stop and play again, either same video or another video, the audio will drop out, noise etc.
if I do the same in another MBP 13" 2011, 4G ram, os x 10.7.6. everything is fine.
would it be some driver program on mbp 2010 that is not 100% compatible to hdmi audio?
base on this, I can assume the hdmi cable and hdmi adapter is not the issue.
please suggest.
thanks.

I believe so. See this writeup about a Thunderbolt to HDMI cable, and, in particular, its reference to audio.

HDMI Audio issue / Strange aplay -l output

I've yet to get HDMI audio output to work correctly. I've tried the advice to use aplay -l to find my card/device number, but my output seems different from every other one I've seen online. To my knowledge, I have the proprietary NVIDIA drivers installed correctly.

there has been additional data to allow the user to determine which device. I've tried to play audio using aplay through each device and none produce sound output. I have a Windows drive on this computer on which sound works, so it isn't a hardware issue. Anyone know how I can fix this?
Update: After some more research, I've been able to force white noise through with:
sudo speaker-test -Dhw:1,7 -c2
I can also force aplay to play a .wav file. But after multiple go's trying to configure asound.conf, I can't seem to get anything else to play.

i had the same problem the device you need to use is propably 9 install alsa-utils if you havent and run alsamixer then select the Nvidia device and check if all 4 of them are unmuted (the last three will probably be muted...)
You can unmute them with M after that test the devices again with aplay

HDMI Audio issue with Samsung Plasma

Hi all,
I have a mid 2010 Mac Mini that I bought for my HTPC. I am unable to get the HDMI audio to work after trying a number of connection possibilities. Here's the setup -
Mac Mini to Samsung via HDMI cable (1.3a) in either HDMI port - no audio
Mac Mini to Samsung via HDMI cable currently working for my uverse service - no audio
Mac Mini to Insignia LCD via HDMI cable in either HDMI port- no audio
I thought it was hardware, so I made a genius appointment and took it in. They gave me a new mini. Same exact issue.
When I switch to SAMSUNG in the sound properties, it tells me "The selected device has no output controls"
Video works fine.
What am I doing wrong? Did I just get two bad boards? This is really freaking annoying.

I have the same issue... perfect image on a Samsung TV UE32EH5300, but no sound. I tried changing the input name to HDMI/PC (and tried all others) with no success.
Altough I noticed one rare thing. I opened Mountain Lion AudioMidi Configuration and selected the HDMI output. Can't move the volume controls because these are supposed to be controlled on the TV. But when clicking at the Speaker configuration and making a test for L/R speakers... each TV speaker (connected by HDMI) reproduced statics.
THEN I'M CONFUSED!!!!... how can I hear sound produced by the computer but can't have the normal audio on HDMI???
Any help???

HDMI Audio Issue/Radeon Grapics Card [Solved]

Hello All,
New user to Arch, been using linux for a little while longer. I'm trying to set my HDMI out as default output, but cannot seem to make it work. I've tried the wiki, forums, and websearches, but none of the methods (and variations thereof) seem to work for me. The hw must work, for I am listening to music as I type via HDMI, but I must go into VLC>Audio Output>HDMI. So if someone could help me out, walk me through it, I would appreciate it very much. I'll post some info below, sorry in advance if it's not everything needed. If you want to assume I am a complete n00b/idiot, I will not be offended. Thanks in advance!

OK, I think I've got a resolution. I used a combination of several wikis to get it right, mainly:
ALSA-Gentoo Wiki
ALSA-Arch Wiki
ATI#HDMI Audio-Arch Wiki
Kernel Parameters-Arch Wiki
I searched a number of other pages I don't remember right now, but these were the most helpful as I recall. I again added "radeon.audio=1" to /etc/default/grub per the "Kernel Parameters" and "ATI#HDMI Audio" Arch Wikis. I then modeled my ~/.asoundrc to match the Gentoo Wiki example, with a slight tweak to fit my hardware. That file now looks like this:
GNU nano 2.2.6 File: ~/.asoundrc
pcm.!hdmi {
type hw
card 0
device 3
pcm.!default {
type plug
slave {
pcm "hdmi"
It's been a few days, with rebooting everyday, and so far so good. Audio programs (eg. VLC) and flash content are working just fine. However, speaker-test & aplay -D give no errors and the scripts run, but no audio is actuallly produced. ??? Is this a problem, or can I continue to ignore it?
Anyways I consider this pretty much resolved, and hope this helps anyone else with this issue. Cheers!!!

Thunderbolt to HDMI - audio?

I have a Macbook Air (2012) running Maverick (OSX 10.9.2). Will the Thunderbolt port provide video and audio to an HDMI converter cable for HDTV display of media played from the Mac?

I believe so. See this writeup about a Thunderbolt to HDMI cable, and, in particular, its reference to audio.

Mac mini 2011 HDMI audio issues

What are the known issues with HDMI audio with Lion and the new Mac minis?
I'm in the process of swapping out an older Mac mini that was connected to my home theater (Pioneer SC-05 reciever, Pioneer TV), with a new 2011 i5 Mac mini. The old Mac required use of a minidisplay port to HDMI adapter, and a toslink adapter to get audio to receiver through an optical cable. Previous setup was working fine, but with the new 2011 Mac mini swapped in with the direct HDMI connection to the Pioneer SC-05 receiver, I'm not getting 5.1 audio. The video is fine and is being passed through to the TV, but the receiver is only doing dolby prologic audio, even though the movies are Dolby Digital 5.1.
I'm using Plex .934 on the Mac. Audio on the Mac is set to HDMI. Plex is set to Dolby (AC3) digital capable receiver, etc.

Hi All, I have the new 2011 macmini to replace the 2010 version. I had issues with HDMI sound as well, but it turns out the issue lies in having AND the HDMI cable in AND a toslink/headphones cable.
In the 2010 version you could select the Sound output to go via HDMI or Analog.
In the 2011 version (if you have plugged-in a cable in the headphones) the HDMI sound output is impossible to choose. It is only selectable when you have unplugged the headphones cable. So what is the use of the Output settings if you cannot select anything if you have more than 1 output.....
The guy form AppleCare told me this is a firmware bug that 'should' be solved.....
When I unplug the headphones and start a movie in Movist, I have DTS and DD. With VLC it does not work, but that has to do with the upgrade to Lion (see the VLC forum).
I assume the firmware upgrade will come soon otherwise I will be VERY dissapointed in Apple quality this time and will certainly stop buying new Apple gadgets when they come out. As this was the reason why I switched from Microsoft to Apple......

Two Thunderbolt Displaysand USB Audio Issue

I have a brand spanking new Macbook Pro 15" Retina (2.7 Ghz, 16GB RAM, discrete graphics chip). I also have two thunderbolt displays, one is about a year and a half old, the other is pretty new.
I also use an Apogee Duet 2 USB sound card.
If I plug the USB soundcard into my Thunderbolt USB, after a few minutes the audio is all distorted. I've so far resorted to using a USB port on the MBP itself, which fixes the issue.
Is there a "Best practices" guide for how to connect up these displays? I currently have them daisy chained, so I have just the two cables going into my Mac which I wanted. Is there a better way to hook this up for reliability sake?

I have this exact same issue. I wish there was a fix but I have been looking for a while. Apple must know about it!

X1 Carbon (3rd Gen, 2015) HDMI audio issue

Hi,
i recently used my X1 to connect it to my TV via HDMI. It worked like a charm. Yesterday it stopped working (Nothing was changed. Audio was working, lid was shut. Lid was opened the other day, audio is not working...). I get a video signal, but no audio. To verify, that this is no issue on the hardware defect issue, I booted to an installed Debian and there I get an audio signal over HDMI.
After that I deinstalled the audio and graphic driver, rebooted, installed the audio driver, rebooted again, installed the graphics driver, rebooted again. Still no working audio over HDMI.
After that I tried the procedure above again but installed the audio driver first. Still no success.
The HDMI audo device does not show up in the playback device tab. Not even if I select to show me disconnected devices.
OS: Win 8.1 64bit, drivers a all newest.
What to try next? Any ideas?

You are welcome...you need not worry about the temperature...the temperature (or the boot etc.) was on the older SM 941 one problem..and also you will not have any problem with the latest bios version on the carbon .there is no white list in the carbon bios etc.for the ssd's (that means you can use any ssd's on the carbon..Samsung ,Toschiba ,Intel etc..at the moment only Samsung is x4 speed and the fastest on the market) in the bios..and the bios will detect it as a bootable drive whitout any problem...and that's the truth and fact.Best regards..

HDMI audio issue

I regularly use my l755 to stream video through an hdmi cable to an lcd tv. Recently, when i hook up the laptop to the tv, all other sounds come through the tv speakers except video sounds. This is the case with multiple tvs and video formats, (netflix, youtube etc) Please help!

Can you check the laptop's full model and part numbers from the label on the bottom? Don't include the serial number.
What version of Windows are you using?
No matter what type of video you use, it plays through the laptop's speakers? Do any of the laptop's sounds play through the TV?

T410s/T410/T510 DP- HDMI, audio questions, survey

Hi,
after all the confusion concerning DisplayPort-audio and the T-series, I decided to find out for myself and test it at my local Lenovo dealer.
As my dealer had not a single HDMI and audio capable output device in his shop, I brought my own Medion MD 20226 LCD TV, which has 2 HDMI-in ports.
The idea was to use a 2m DisplayPort->HDMI-cable provided by the dealer in order to connect the T410s in question to my little TV.
Background: Due to the misleading information from Lenovo concerning the last generation T400s/T400/T500 models and their audio over DisplayPort issue (no audio at all), I expected to get a picture without any problems but that I would need to figure out how to enable the sound by changing some settings inside Windows 7.
What happened: Actually neither me nor my dealer were able to get ANYTHING out of the DisplayPort, when using the DisplayPort->HDMI-cable. There was NEITHER video NOR audio!
I should point out that at the time being my dealer only had T410s models without the (maybe) switchable NVidia graphics.
Another point that I want to emphasize is that, after 45 minutes of trying everything we could to make it work, we switched to the T510 that was standing right beside the T410s in his show room. Unfortunately I was too confused to ask what kind of graphics setup this machine had, but the result was the same: no video, no audio at the TV.
As it is apparent that there are quite a lot of confused Lenovo customers out there that have similar questions:
I HEREBY FORMALLY ASK FOR A DETAILED AND IN-DEPTH INVESTIGATION/CLARIFICATION OF POSSIBLE DP->HDMI, DP-AUDIO AND DP->HDMI-AUDIO ISSUES WITH THE CURRENT T410s/T410/T510 SERIES (all combinations of graphics cards).
Of course I think that it would be best if one of the Lenovo engineers would take care of that in one of the Lenovo blogs.
But until then, it might be a good starting point to ask those of us, who already have a T410s/T410/T510.
So I just start right away:
MODEL:                   T410s (NUK39GE / 2912-39G)
used GPU:              Intel GMA 5 / QM57
DP->DP-video:       not tested
DP->DP-audio:      not tested
DP->HDMI-video: tested->not working
DP->HDMI-audio: tested->not working
As I said, I was only able to test it at my local Lenovo dealer and I gave up after around 1 hour of testing. So it might be, that someone who has more time and resources (different adaptors) might be able to get it running.
So to all of you out there with a new Tx10(s), please take the time, find your next HDMI-TV and try it.
And to Lenovo: as long as there is no official statement concerning this, I will keep asking for an official response ;-) (and THIS time, don't blame the chipset, as the new Intel-Calpella has all the HD-video/audio goodness one could ask for: wiki article on Intel Calpella and its DP features).
Thanks for reading all this!

How do you setup HDMI audio with "Nvidia Quadro 4000 for Mac"?

So I just purchased a new Mac Pro:
Mac Pro (5,1) 3.33 GHz 6-Core
8 GB Ram
ATI Radeon HD 5770
1TB HDD
OS 10.8.3
I also purchased a new Nvidia Quadro 4000 for Mac Graphics Card because the 3D animation software I'm using (Blender) requires this card to accelerate render times.
I have installed the card and all is working well as far as I can tell except for the HDMI audio. According to the specs on Nvidia for this card, it DOES support HDMI audio through the Display port. I have my HDMI cable plugged up and the video works great. However the audio option does not show up in the System Preferences. (Here is the page for the graphics card. Look under "specifications" at the bottom for the audio part. http://www.nvidia.com/object/product-quadro-4000-mac-us.html).
I did find a link for a kernel addition for HDMI audio but it stated "non-Apple Nvidia cards" and this one is specifically for Mac. Here is that link: http://forums.macrumors.com/showthread.php?t=1499797. (I also plan on posing the same question there.)
The reason I want the HDMI to work is I'm using a TV as my monitor.
Now I did try the HDMI with the ATI Card and both the audio and video work great.
What I did for a quick work around is install both cards and use the GPU processor on the Nvidia for the animation program and use the ATI for the actual port and this fixes the hdmi audio issue. However this takes up pretty much all of my PCI slots and seems like a waste of space and power.
Has anyone else run into this problem and found a solution?? Any guidance would be greatly appreciated.
Thanks!

I went ahead and tried that extension that I found. It worked!
I guess Mac just didn't include the audio support in the driver that it includes. Below is were I found the instructions and download. It includes a shell script that installs the kernal from the Terminal prompt. The instructions were clear and installed with out a hitch. There were also instructions to remove it if there were issues.
Here is the link:

Thanks again and hope this helps.

HDMI audio via AVamp

Hi, apologies, I know this topic has been covered in part elsewhere, but I have tried everything but still have issues.
I have a PVR, Blu Ray Player and Apple TV connected via HDMI to an Arcam AVR350. This in turn is connected via HDMI to a Pioneer plasma.
When using the Blu Ray or PVR I get audio in surround via the Arcam and via the TV speakers if I wanted it. However, if I switch to Apple TV I get no sound through the amp as such, instead the sound is via the TV speakers. Odd...I've tried all of the suggestions from the ATV support page and no difference. My other two devices work perfectly. Any ideas? The ATV is two weeks old and patched to the latest version. Do I have a duff ATV??
Thanks and regards
Hunttheshunt

Hi thanks for the response.
I understand what you mean...however my Sony Blu Ray player provides sound to both TV speakers and my surround setup. I have used exactly the same cables, setup etc but with the ATV I only get sound through the TV speakers, which would seem to suggest that it's the ATV that has the issue. I've seen a number of posts with regard to HDMI audio issues so wondered if it is the unit at fault. Any other ideas?
Thanks and regards

Audio issues with HDMI connection

I just bought a toshiba 40l5200u (40'' 1080p) and I'm having issues with connecting my macbook pro to it with a HDMI cable. The picture looks fine and everything, but the audio is horrible. The bass specifically sounds terrible, very gravelly if that makes sense. Dialogue is usually fine, but when something loud, for example, happens in during a movie the audio (bass mostly) gets very distorted, scratchy, and just a pain to listen to. The audio sounds perfectly fine when I play a DVD through a dvd player, so it the speakers on the tv don't seem to be the problem.
I was originally using a "Cable Matters Gold Plated Premium Mini DisplayPort | Thunderbolt to HDMI Male to Male Cable in White 10 ft" (here's the Amazon link: http://www.amazon.com/gp/product/B004CADYDO/ref=oh_details_o04_s01_i00?ie=UTF8&p sc=1). I thought the issue might be with the HDMI cable, so I recently bought a "PNY A-DM-HD-W01 Mini DisplayPort to HDMI Adapter" (here's the Amazon link: http://www.amazon.com/gp/product/B007B6YPAM/ref=oh_details_o00_s00_i00?ie=UTF8&p sc=1) and another HDMI cable, "BlueRigger High Speed HDMI cable with Ethernet, Supports 3D and Audio Return" (here's the Amazon link: http://www.amazon.com/gp/product/B003XM9774/ref=oh_details_o00_s00_i01?ie=UTF8&p sc=1) but that didn't fix the problem at all.
What I can deduce is that the problem isn't with the tv's speakers. Other than that though I have no idea. Any suggestions on what to do? I would be very appreciative. Thanks.

It sounds like a software problem. Try updating your Flash software and your audio drivers.

Issue with HDMI audio output

Hello everyone,
this is my first post in Arch Linux forum. I am a Newbie but have always managed to work things around with ArchWiki documentation, but I am having an issue I could not solve for some time now.
My HDMI audio output was working fine, but stoped working about a month ago, maybe due to some update. I use the open source ATI driver (xf86-video-ati package), and enabled the kernel parameter radeon.audio=1, like it is documented.
My graphics card is a Radeon HD 3650. I checked for the compatibility of the driver (http://www.x.org/wiki/RadeonFeature/#De … ting_names) and it seems to be ok.
Do you have any suggestion to help me?
Thank you in advance
