I'm losing HDMI audio just like 10.8.5

Is anybody else suffering with a loss of HDMI audio after display sleep? It's the same issue that was supposed to be addressed with the Mountain Lion 10.8.5 update:
https://discussions.apple.com/thread/5306667?start=0&tstart=0
To get audio back I'm having to reboot again. I thought it had been resolved but since upgrading to 10.9 Mavericks it's back again for me.

Wanting sound quality closer to HD caliber. Using gigaworks. Just bought a vid card with hdmi audio

I just got a GTX 560 TI, and my dilemma arose after installing this card and then trying out the HDMI audio, and being amazed at the sound quality I am NOT getting by simply using my sound card. Here are some of my specs which are relevant. I have the said video card, a Sound Blaster X-Fi XtremeGamer, a Samsung 40" LCD I use as a monitor, and an Asus P5N motherboard. Also, I am using Creative Gigaworks 7.1 750s speakers. I'm running a mini-hdmi to hdmi cable from my card to TV. Basically I am hearing sound quality from my TV that is absolutely superior to anything that has come out of my speakers and am now wanting to achieve better sound quality for my speakers, but how? Should I get a Sound Blaster X-Fi Titanium Fatal1ty? New speakers is definitely not what I am looking for right now, and besides that, they are a very powerful set of 7.1's that you just can't find anymore. I know there are HDMI sound cards, but I doubt I would be able to plug my speakers into those. Is there better software I can download to go along with my sound card? I've updated PowerDVD on the off-chance that it would help (even though I knew it wouldn't). I'm really not sure how much help getting a fatal1ty sound card would be. Any suggestions on how to get my PC speakers running up to or NEAR to HD quality?

$200 at all? So no new sound card? Or 200 for receiver only? So following setups are possible using a receiver:
- Use SB, Receiver: so you connect from SB analog to Receiver and from their analog to Speakers, use HDMI/DVI for video seperately. IMHO Bad as it uses much analog points and would have bad sound quality. As long as you don't buy a quality SB, real good analog cables, good receiver. And so we speek over 1000$
- Use GPU and Receiver directly via HDMI. Then Analog to Speakers and HDMI/DVI to TV. No real extra SB needed, but be aware that if you got an nvidia card it may be you need to connect the sound via SPDIF - check: [url=http://www.hardwaresecrets.com/article/600/">http://www.hardwaresecrets.com/article/600/[/url] . But as SPDIF only provides 1,5Mbit/s (6Mbit/s in rare cases) and formats like Dolby True HD/Digital Plus, DTS HD Master need 18-25 Mbit/s you won't get highest quality possible as software downsamples quality. But i think anyway these formats are not supported by GPU, thats why 3rd solution exists
- As written above use GPU to SB via HDMI, SB to Receiver via HDMI, Receiver to Speakers via Analog. Most expensive as you need new SB and Receiver but thats the way they want high end sound being provided.
Keep in mind that on 2nd and 3rd solution the receiver must have HDMI I/O! Also check HDMI Version! 1.3/1.4? 7.1 is not nessacary (as your speakers can do 5.1 to 7.1 upmix [url=http://support.creative.com/Products/ProductDetails.aspx?catID=4&subCatID=792&p rodID=9306&prodName=GigaWorks%20S750&subCa tName=Multi-Channel%20Systems&CatName=Speaker+Systems& VARSET=prodfaq:PRODFAQ_9306,VARSET=CategoryID:4">h ttp://support.creative.com/Products/ProductDetails.aspx?catID=4&subCatID=792&p rodID=9306&prodName=GigaWorks%20S750&subCa tName=Multi-Channel%20Systems&CatName=Speaker+Systems& VARSET=prodfaq:PRODFAQ_9306,VARSET=CategoryID:4[/url] ) but you buy a receiver normally just once and so i would recommend to get that too. If you want a good one LipSync, Deep Color, x.v.Color should be onboard too.
So on the second part - why do you think you have to buy new cables and sub? And did i get you right - you want to directly connect the speakers with receiver? No, you have to connect to a sub. Well, if you want the receiver to do the upmix you need the seperate available 4x Stereo or RCA cables as i don't think an receiver will provide 7.1 via the supplied 4x to 3x 7.1 Audio cable.

Just got a new computer and I want to hook up my itouch and treat it just like i did with the last computer, without losing any data. What can I do?

Help me please! I'm a new college student trying to make my new computer just like the family computer, which has all of my itunes, ipod sync "station", and etc.How can I hook up my iTouch to this new computer and treat it the same as i did on the old?
P.S.-and just like everyone else, is there a way to do it without losing all my hard earned data?

Make sure you cpt the iPod backup file from the old compouter to the new one. That file is located here:
Mac: ~/Library/Application Support/MobileSync/Backup/
Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
Windows Vista and Windows 7: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
- after you move the other stuff to your new computer, connect the iPod to the new computer and restore the iPod from the backup you just added to the computer and then sync.

No HDMI Audio from PNY Nvidia G210 Card - Please Help [SOLVED]

***** It's now working! *****
Thanks to some of the posts on the XBMC and Ubuntu hardware forums. I picked up a lot of pointers.
When using this card with XBMC, There is no need at all for an /etc/modprobe.d/sound.conf with probe masks etc. and there is no need for a /etc/asound.conf either (if you are going to just use XBMC like me for your HTPC setup)
All you need is ALSA 1.0.23 installed and at least be running kernel 2.6.34. aplay -l should reveal multiple (4) Nvidia devices as shown in my previous text further down this post, this is fine, however only 1 of these Nvidia devices will actually deliver sound to your TV via HDMI.
In XBMC, goto System Settings, Audio Settings, set device to "Custom" and enter only ONE of the following and then try and play a movie or music in XBMC... (My G210 Nvidia soundcard is card 1 as I also have onboard audio at card 0 so bear this in mind when applying this method to your setup e.g if your HDMI soundcard is card 0 then the first thing to try is plughw:0,3)
plughw:1,3
plughw:1,7
plughw:1,8
plughw:1,9
My PNY G210 card worked using a "Custom" device in XBMC of plughw:1,8
If you are not using XBMC and are using for example a Gnome desktop then you can apparently get sound working by using the text in the code box below in your /etc/asound.conf (this will ensure alsa defaults to the correct card and sub device for hdmi audio) again ensure you are using the correct card number and device number. You can validate this by testing audio as follows from the command line "speaker-test -D plughw:1,8 -r 44100" and simply work your way through the 4 devices until you find the one that works.
pcm.!default {
type plug
slave.pcm {
type hw
card 1
device 8
Given the amount of testing and reading I have done on this, I wouldn't be surprised if this method works for any G210 Nvidia cards and HDMI audio, as the logic seems sound (if you'll pardon the pun! :-))
Hopefully someone will find this helpful.
Original problem text below this point......
Hi Guys,
I am about to give up on this as I cannot get HDMI audio to my TV no matter what I try.
The card is a PNY Nvidia G210. I am running Arch Linux x86_64 and ALSA 1.0.23 and Nvidia driver 256.33

Disabling the motheroard onbonard Intel Audio makes no difference and manually compiling and installing the very latest ALSA driver makes no difference.
Has anyone got HDMI audio working on this card under linux?
Thanks in advance for any help you can offer as I have now run out of ideas and if I can't get this to work will have to revert back to my old ASUS EN9400GT card which takes s/pdif from the motherboard for audio out to HDMI.

[SOLVED] ATI HDMI audio fails when playing videos... fine otherwise.

On a fresh install of Arch Linux, despite being an amateur at best. I'm using ATI HDMI audio using the open source driver, on GNOME 3. I'm switching to Catalyst after posting this to see if that might help, somehow.
After adding the radeon.audio=1 to the bootloader, audio on the system began working just fine as long as I restricted myself to audacious (haven't tried another audio player) or the system sound tests. When I try to use VLC, or mplayer2 for that matter, not only does it not play the audio associated with the video but NO audio will pass through the system at all. I have tried changing the audio source in VLC, although default should work... nothing works. Changing the audio in VLC will cause the system's audio to max out. Changing it back to something else doesn't help, but I can change the volume after closing the video programs, and after a few clicks it will go back to the "bloop" sound that confirms volume changes. Everything works fine again.
I have been at this all day and I am at wit's end. My google searches are getting way too long to be of any help. Any pointers or obvious things that I've missed in my caffeine haze would be greatly appreciated. Thanks!
...SOLVED by switching to Catalyst drivers from open source.

Hi,
Yesterday I upgraded to kernel 3.13.4 from 3.12.9 and
HDMI audio through my nVidia GTX660 card stopped working.
The problem occurs both with nouveau and nVidia drivers.
My system is an aged Intel quadcore Q9400 on a Intel motherboard.

Thank you very much, silenceleaf.
I managed to make it work with some tweaking like you said.
But only after a deep power cycle, unpluging any power to the system.
Just turning off the machine's power button was not enough. Odd!

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!!!

OS X 10.8.5 mac mini hdmi audio output issue

I am running a 2012 Mac Mini with OS X 10.8.5 and my Mac is set for audio and video output via HDMI to my AV receiver / TV. I have recently noticed that HDMI audio output ceases to function once the computer goes to sleep. A full computer restart is required to resolve the issue which is an inconvenience to say the least.
Or is anyone aware of a simple fix?
All my software is up to date, the HDMI lead and connection works fine for video and audio works fine after a restart so it must surely be a software error. Worked fine until the latest OS X update...
Grateful for any help!

XBMC: HDMI audio starts out OK, then gets distorted after few minutes

Hi,
I have posted about this on the XBMC forums, but one of the developers kindly informed me that they do not support XBMC on Arch Linux in any way, so I should take my queries elsewhere. I am hoping that someone here might be able to shed some light on my issue.
I am trying to use XBMC 13.1 (xbmc-13.1-2) with Samsung EH5300 32" Smart TV (2013 model) over HDMI connection. The HTPC computer is AMD-based (AMD A4-5300 APU, which includes Radeon HD 7480D GPU), and runs an up-to-date Arch Linux (last full system upgrade on 2014-06-26). I am using the open source "radeon" driver (xf86-video-ati-1:7.3.0-1). Everything has been great except the sound:
The sound starts out fine, but a few minutes later it begins to get distorted. At first it sounds like reverb affecting voice only, but with time the distortion increases until it sounds kind of cued TV noise. If I restart the video, the sound works again for a while. If I change options in Settings -> System -> Audio Output, like the number of channels or pass-through, the sound is again good for a little while. If I enable or disable "Stereo Upmix" or change audio stream from the "Audio - Settings" dialogue window available during video playback, it too seems to "reset" the sound to sounding normal for a while.
Has anyone seen something like this?
I have tried different videos, and it seems like HD videos are affected more than SD videos, starting with distortions only a few minutes in (except the one Xvid video, which was fine for 15 minutes). Some SD videos are completely fine, some start having distortion issues only after 20 minutes or so. Judging from video information, if the video uses 5.1 channels (all HD videos fall in this category), it definitely gets distorted; if a video only uses 2.0 channels (like the SD videos), some are fine while others get distortion later on. I have "Number of channels" in Audio Output settings set to 2.0. Changing this (or any other audio settings) has not affected the distortion.
Following Arch Wiki: Radeon note about HDMI audio, I tried adding radeon.audio=1 to the kernel line; this did not solve the issue, just added some visual glitches.
In the XBMC debug log I posted, the distortions happen at around 17:26, though there is absolutely nothing logged at that time, even though I enabled "Verbose logging of AUDIO component" in the Debugging settings. The video I was playing there showed the following in the information window: 720 H.264 dts 5.1 16:9.
Any suggestions, ideas, or experiences would be appreciated. It definitely seems to be XBMC issue, since I was able to play the same HD video through mplayer without any problems (for at least half an hour, which would have already showed distortions several times through XBMC).

Hi GDykes,
OK Imagine that Connection speed from your ISP is like an empty freeway. You can go full tilt (upto that road's speed limit)
Bandwidth is like a busy freeway where you only get to go as the bit you are in allows.
Reducing the Bandwidth in iChat or in the System Preferences > Quicktime > Streaming tab is like a vehicle that has a maximum speed that is slower than the speed possible on the freeway.

Is Auto Switch to HDMI Audio Possible?

I have a dv5-1235dx laptop and use vista, and finally figured out how to get the hdmi sound to work after searching this board and other sites (by manually choosing hdmi as default playback device), but it appears this requires a manual switch every time the hdmi cable is plugged in. Have updated all drivers etc. (intel high definition hdmi), but still requires manual switch when I want to watch something on my hdtv. Is there any other driver or solution that would just switch over to hdmi audio automatically when plugged in? Seems like this is a common issue, and one that ought to be fairly easy to resolve, but i'm not really that tech savvy so maybe it's more complicated and just an HP/intel issue that can't be resolved? Anybody have any workarounds for this?

First of all, its not a Intel/HP issue and your playback device will automatically be set to speakers once you disconnect your HDMI cable.and be automatically set to HDMI once you connect your HDMI cable to the laptop.
Its similar to how you connect your headphone to headphone jack on the laptop. Make sure setting - HDMI as default playback device has been done when you have disconnected your HDMI cable from the laptop and not when its connected to the laptop.
In order to do,
Go to Control Panel\Hardware and Sound and click on sound . On playback tab, right click on white (blank) area and you would see 2 options (Show disabled Devices and Show Disconnected Devices). Make sure both options are checked to have all playback devices listed.
Now right click on HDMI ouput device option and ensure "Set as default device" option is checked to hear audio from external display while playing picture on external display.

Try using this command with all the listed devices until you hear sound from one of them.
aplay -D hw:1,9 /usr/share/sounds/alsa/Front_Center.wav
Also, go into alsamixer, press F6 to go to the right sound card, and unmute everything by pressing M (OO means on, MM means muted). For me, I have a similar aplay -l, and for some reason, the correct device for me also hw:1,9 (no clue why there's four of them...), and things like pulse just assume it's 1,3. If you use ALSA, it should be easy to set it up in /etc/asound.conf. If you want pulse, you might have to go into /etc/pulse/default.pa and add a line like this in order for the correct card to show up, it worked for me on my GT430:
load-module module-alsa-sink device="hw:1,9" sink_name=digital_output

HDMI Audio is not on Playback List

I have a Pavilion dv7 running Windows 7. I've had the laptop for 3 years now with excellent service. Recently, I purchased a flat screen TV and I would like to play programming from my laptop to the TV by HDMI connection. I have a high quality cable that has worked in this case sporadically, since the HDMI audio playback option likes to periodically disappear from the Playback Device list. The few times in the past when the HDMI audio option has gone missing, I have somehow managed to get it to return by replacing drivers or doing some other kind of recovery. Right now, it's missing and I can't get it back.
I have tried a number of the standard fixes to no avail.
First, I checked to see if the IDT High Def Audio CODEC was "disabled." No, it's "running properly" and is "enabled."
Second, I checked to see it the driver for the IDT was up to date. Yes it is.
Third, I tried removing the device and its driver completely and reloading the IDT. Good exercise, didn't work.
Next, I tried running a full set of updates to Windows etc., since I'm not good at keeping up to date. Still doesn't work.
As I write this, I am connected by HDMI cable to my TV and the HDMI Audio option doesn't appear on the Playback List, so that's not the problem.
In case it helps, the Playback Devices list has two entries. The first one is "Speakers and Headphones" and it is my "default" device. The second one is "Independent Headphones".
It's been annoying in the past to have the HDMI Audio come and go like this but this time it's really stubborn and it's making me really crazy. I'm sure I'm missing something but I just can't figure it out.
Help!!!!!

Hello labargephoto.
When you're in the playback window right click in the white space and ensure that "show disabled devices" and "show disconnected devices" are both enabled. You should then be able to activate the HDMI audio.
Let me know if this helps. I hope you have a great day!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"

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.

Radeon HDMI audio out defaults to disabled

A quirk that I've been noticing on my system for a while now is that playing audio via the HDMI cable on my Radeon 5450 doesn't work just after my system has booted (i.e. on the tty console, I do startx manually). Alsamixer doesn't show the output as being muted, and application that play sound (such as aplay /dev/urandom) don't throw an error, but nothing is heard from my monitor's speakers.
Now, if I run startx and try playing audio in an xterm, it starts working. It continues to work if I quit my X session, up until I reboot my system. I've tried weston as well, because that does DRI modesetting like Xorg does, but sound refuses to work if I run that; no matter what I do, no sound can be heard from the monitor speakers until Xorg has run at least once.
I figured it must be something that specifically Xorg does when it detects HDMI outputs as it starts up. This would seem to be supported by the fact that it's possible to mute the audio out for a HDMI output connector via an xrandr command, like so:
xrandr --output HDMI-0 --set audio off
(and likewise with "on" for enabling again).
Another interesting pointer is a control shown by
amixer controls
when ran against the HDMI audio "card", called "HDMI/DP,pcm=3 Jack". The value of this control is "off" when ran before Xorg is started (i.e. no sound), and "on" after Xorg is run (i.e. sound working). This would suggest that the audio "jack" for this output is not detected, despite the fact that there's a HDMI monitor plugged in.
Has anyone else encountered a similar situation with the HDMI audio out on radeon cards? And if so, how did you fix it? Is there a tool somewhere that can do what Xorg seems to do without needing to startx (i.e. NOT xrandr)?
I realize that for most people, audio will only be played after a graphical X session was started anyway (i.e. a music player application), but Xorg won't be the main windowing system forever, and sometimes I like playing music on my console without having to startx (currently using the motherboard's onboard sound until I can fix this), so starting and quitting Xorg just to "unmute" the audio on the HDMI connector seems a long-winded workaround. Plus, it seems quite strange that the kernel can do modesetting on the HDMI display just fine but seems to need a userspace application to tell it when to enable the audio part.
Any pointers, info or docs as to why this is a thing or how to work around it (without Xorg, please ) would be appreciated.
(NB: I've tried looking at the Xorg source code, the result was me getting lost in there with a headache >.< )
Cheers, D^2
EDIT: A bit more poking around:
- Changing the DDX (i.e. to something like xf86-video-modesetting) doesn't affect the sound starting to work after Xorg is run; it would seem this rules out anything weird poking done by xf86-video-ati, so it looks more like the sound enabling does happen at the xrandr level.
- The adformentioned amixer control for jack detection is a read-only property, I can't set it using amixer ("Operation not permitted").

I did what is said here but audio will not work.
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/f16ef16a-2e5c-4725-97e0-9ae1f947c86f ro nomodeset radeon.audio=1
My alsa-info is http://www.alsa-project.org/db/?f=0eb0e … 26897b908c
Notable is the fact that when running
$ aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav
there is no error but the program finishes instantly, rather than being busy for 1.43 seconds which it usually takes to play back that sound.
speaker-test -D plughw:0,3
also rapidly progresses to the next tests.
alsamixer only has one option: "S/PDIF:ON"
One more info: I also have an on-board sound card, which uses the same module, so I disabled it in BIOS.
I'd be glad to have my audio back.
PS: oh. - http://www.x.org/wiki/RadeonFeature

Turn off HDMI audio output?

Hi all.
I have my ATV (current gen) hooked up to my TV via HDMI, and hooked up to my home theater system via optical audio cable. The problem is now, sound is being output on both the TV and the home theater system. I can turn the volume on my TV to off, which is a workaround, but it's a bit kludgy. Is there a way to turn off the Apple TV's HDMI audio output or otherwise tell it to just output the video and not audio over HDMI?

I think it's silly that I can't change the audio output, but I appreciate the help.
I'm actually glad that all outputs work simultaneously - something like a PS3 where you have to choose between optical or HDMI can be a real pain if sometimes you just want TV speaker audio (HDMI in my case) and other times you want the full surround experience (optical to hi-fi).
I'd have no qualms about allowing disabling individual outputs but having them active over more than one is better than constantly having to fiddle in Settings menus each time you want the audio from a different device.

I'm losing HDMI audio just like 10.8.5
