Force 5.1 out over HDMI

So my setup is the following.
Mac Mini -> HDTV -> Surround Sound System
The problem is that I can't get surround to work. I think I've figured out the proble, but I'm not sure of a solution.
To start off, my TV is able to accept any type of audio and pass it on to speakers (including DTS, etc), so that is not the problem. I have tried this same setup using a HDMI converter for my Macbook Pro and it works without a problem. Surround sound works with the macbook pro and a Mini Displayport to HDMI convertor. On the other hand, when I connect from the HDMI port of my Mac Mini to my TV, it only puts out Stereo. My Mac Mini refuses to output 5.1.
I believe the problem is the following. When I connect the HDMI cable to my TV, my Mac Mini reads the information about my TV (that it only has two physical speakers itself) and then thinks that it will only support 2 channel audio. Therefore it refuses to output anything greater then that. Even if I go into Audio MIDI Setup, when I try to setup Multi-Channel audio it won't let me do anything but Stereo. It thinks the TV can only handle 2 channel audio, but it is wrong.
It works with my Macbook Pro, because the Mac isn't reading the TV information, it is reading the mini displayport to hdmi convertor's info, so the Mac gives the OK for multichannel audio to be sent.
What I need to do, is trick the Mac Mini into thinking the TV can handle multichannel audio (which it can) so that it is willing to send this audio to my TV. Otherwise I'll have to buy a receiver, which as a college student, I really can't afford. Does anyone know how this can be achieved or have any suggestions? (I can't use the optical audio port, because I don't have one of those available on my TV).
Thanks for any help!

Hey,
You are exactly right about the cause of the problem. I was trying to do the exact same thing, and wrote a reply in this post:
https://discussions.apple.com/message/12949030#12949030
While some have suggested to use Audio Routing apps like Soundflower or JackOSX, they don't work in this situation because the Macbook is still sensing the TV's "2-channel only capacity" and now allowing you to send multichannel sound through the TV's passthrough.
Some people would say... why don't you connect your HDMI directly to the surround receiver and then pass the video through to the TV... well, my setup isn't capable of that. My TV has an optical audio out which outputs the digital audio out based on which TV source I've selected. That's makes a lot sense.
How does the Macbook negotiate what output formats are available? Using some drivers for the Intel® High Definition Audio car, or somewhere in the OSX software as it interprets the EDID data.
Where can I intercept the EDID data?
Or, does it not use the EDID information and instead sense it this way... I found this PDF about the audio card ....
apparently tries to "sense" the number of channels the HDMI destination widget is capable of handling. In section "7.3.4.6 Audio Widget Capabilities" it describes some auto-sensing stuff.
SOMEONE has gotta know about this problem. I can force multichannel output to my TV using a PC, why not a MAC?

  • Force RGB Color Space over HDMI?

    Does anyone know how to force RGB over HDMI on a Macbook Pro with Retina Display. This is driving me nuts, as I have two U2410's. One is connected via DVI (using the DVI thunerbolt adapter), whilst the other is connected via HDMI. The monitor connected via HDMI negotiates the YpBPr color space, whilst the DVI monitor uses RGB. This makes it impossible to get the two monitors to produce the same colour. I can set the monitor to RGB within the OSD, but that just produces a mismatch of green and purple colours - in other words, the signal coming from the mac is still YpBPr so obviously setting the monitor to RGB ruins the colours completely.
    There must be some driver setting or something to force HDMI to output RGB instead of YpBPr. Through Googling, it seems this applies to pretty much any Mac with a HDMI port, hence it's got to be a software issue, that's why I chose this forum. I'm about to duck home (I'm at work) and grab one of my HDMI -> DVI cables to see if that provides a work-around.
    What happened to Mac's being a professional device. Surely they can't claim superior colour management if something as fundamental as the monitor's color space can't be controlled.

    I have given up trying to use a Mac with a Dell or Samsung or Viewsonic monitor. Just ordered and received a StarTech.com DP to miniDP cable and was disappointed to see only YpbPR being output to my 22" Dell monitor. This is on top of the general fuziness and inaccurate colors. I've tried all sorts of other cables and adapters, both Apple and 3rd party, and the plain sad fact is that none of them work properly.
    I plug in an old Cinema Display or a new Apple LED display and it works perfectly, colors look great, type isn't fuzzy.
    I boot into Windows 7 on the same Mac using Bootcamp and my Dell monitor works perfectly.
    It's OSX's display drivers that just don't play nice with Dell or Samsung or Viewsonic monitors. There's no other explanation because every other combination has problems with OSX and non-Apple monitors.
    I can get into the long description of every possible adapter and cable I've tried (as well as the terminal command to adjust font smoothing). If I want the type to look right and the colors to look right, I just have to use an Apple monitor, which is aggravating as I have plenty of larger monitors here at work that I'd rather use.
    Brief summary:
    Three different MBPs, one a Retina display. Four different monitors from 3 different manufacturers, each with various connection options (HDMI, VGA, DVI, DP). DP to miniDP cable, DVI cable with Apple DVI to mDP adapter, HDMI to DVI with mDP adapter, couple of other similiar combinations of cables and adapters.
    Bottom line is that all the screwing around produces a low quality, poor color accurate picture when the MBPs connect to 3rd party monitors. Plugging in the MBP to an Apple monitor (as old as a 2006 era Cinema Display) using any combination of adapter or cable looks great. Plugging in Windows 7 machines, either a dedicated Dell laptop or the MBPs in Bootcamp mode, all monitors look great. Also note that in OSX, the signal recevied by the monitors is YpbPr, but the same laptop in Bootcamp Windows 7 outputs RGB.
    Hence, my guess that OSX display drivers are wonky except when plugged into an Apple branded monitor.

  • G62-a50sf : (only) audio out over HDMI?

    We have a G62-a50sf notebook at my gf's place that we'd like to use as the source for a (somewhat) audiophile audio set-up.  One possibility to get better-than-headphone-output into a good receiver AND avoid using a separate DAC would be to feed the digital audio output over HDMI to the receiver.
    The question I'm hoping to get an answer to is: will this be possible while retaining video output on the laptop's own screen?
    thanks in advance,
    René

    Sorry, but your Mac doesn't send sound over HDMI, only mid-2010 and later MBP's send sound (and even then some require different adapters).  Yours is a 2009 MBP, so only video will go over the HDMI cable.  You will need to run audio from the audio out to your TV or digital audio out from your optical audio out to your receiver.

  • Audio cuts out over hdmi

    My current setup is a 2010 mac mini running OS X 10.7 with audio and video going through a HDMI cable to a onkyo receiver which then passes sound to my home theater speakers and HD TV. Every now and then, the audio will cut out for about 4-5 seconds but the video will be fine. When the audio cuts out, the status display on the receiver will show "no signal". This never happened when it was running OS X 10.6. Has anyone else experienced this problem? Any suggestions for a fix would be greatly appreciated.

    Hello dmurfett,
    Welcome to the HP Forums!
    I see you have some issue with sound cutting out at higher levels. Can you please confirm if this is happening with the notebook speakers and headphones, or if it's only one of them.
    Just to make sure the correct driver is installed and not the Windows driver, uninstall the audio drivers and reinstall using one of these downloads: 
    Windows 7 64-bit - IDT High Definition (HD) Audio Driver
    Windows 8 64-bit - IDT Audio Driver
    You can also try this:
    1. Open Control Panel and click Hardware and Sound.
    2. Click Sound.
    3. While on the Playback tab double click on Speakers to open the Properties window.
    4. Go to the Advanced tab and click the Default Quality drop-down.
    5. Select the highest quality output (the highest Hz setting), and click Apply.
    6. Click OK, and test this setting.
    If this doesn't work, try the following:
    1. Open Control Panel and click Hardware and Sound.
    2. Click Sound.
    3. Click on the Recording tab, and double click Stereo Mix to open the Properties window.
    4. Go to the Advanced tab and click the Default Quality drop-down.
    5. Select the highest quality output (the highest Hz setting), and click Apply.
    6. Click OK, and test this setting.

  • 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.

  • Force RGB over HDMI connection??!! (Dell U2414H)

    Since Apple's support refuses to help me, nor do they seem to grasp incredibly basic technical information regarding monitors, I'm turning to you, dear forum.
    I just bought two brand brand and professional calibrated Dell U2414H monitors to use with my Mac mini workstation in an extended desktop environment.  ...even though Apple themselves erroneously told me I'd be able to daisy chain these monitors over the Thunderbolt connection using MiniDisplay Port 1.2 MST... (they were wrong, their GPU doesn't support DP 1.2)...  So, I resorted to plugging the second monitor into the available HDMI port.
    Problem:  The Mac OS will not send the right color space (RGB) over HDMI.  It sees the monitor as a TV for some reason, and will only send YPbPr... Therefore, my monitors that I paid extra to have calibrated perfectly, do not match.
    I ran this script: http://embdev.net/topic/284710#3027030
    but it didn't change anything.  I'm searching for new solutions now...
    Can anyone help?

  • 5.1 Surround over HDMI: Solve one problem, another rises up.

    UPDATE 1:  After a good night's sleep, and after doing a bit more reading on alsa-project.org (big props to this page), I managed to get a much better ~/.asoundrc together.  It solves all my problems, and I can do everything I need.  I've preserved the post below in case anyone else runs into these issues, and I'll post my solution as a response to this post.
    UPDATE 2:  Looks like I celebrated too early.  Got more strange problems.  Screw it, I'm going back to PulseAudio.  I just wrote a wrapper script to kill and restart Pulse for applications that really, really need ALSA.
    Okay.  I've almost completely worn out my fingers trying to get this working.  I feel like I'm playing Whack-a-Mole.  This is a bit of a lengthy post, but I'll try my best to describe every problem I've encountered in as much detail as I can, followed by the solutions I found, followed by the problems each solution brought with it.  By going through everything this way, mole by mole, hopefully it'll be easy to follow along and help me come to a universally working solution.
    Summarized Version of Problems:
    5.1 surround works only on specific applications which are robust enough to allow me to manually specify audio output options, and only if ALSA isn't configured at all
    once I've configured ALSA, sound works on every application, but it's all downmixed to 2.0 stereo from this point on
    installing PulseAudio lets me choose 5.1 surround as a default, but brings with it its own problems and drawbacks, namely the lack of passthrough support for encoded streams
    Long-Winded Version:
    I have my computer connected over HDMI to an AVR with a 5.1 surround speaker system.  At first, I didn't have anything configured in ~/.asoundrc (or its global equivalent, /etc/asound.conf).  Neither file existed, so everything was running off defaults.  I got the name and device number of my card from aplay, ran speaker-test and played a six-channel test file in mplayer.

    Everything seemed well, all six channels played from the correct location on both tests, but I did realize that the device number of the card was 3, not 0.  A lot of applications that aren't as configurable expect the default card/device to be set properly, and audio won't work in those applications without specifying that in ALSA's configuration.  Knowing this, I set the following in my ~/.asoundrc:
    pcm.!default {
    type hw
    card HDMI
    device 3
    ctl.!default {
    type hw
    card HDMI
    device 3
    This, however, ended up causing more problems.  Oh, it made sound work on everything by default after that, but only for one application at a time!  That surpised me, as I thought ALSA's big advantage over OSS is that it can multitask.  Running the speaker-test the way I did earlier turned out fine, but when I tried playing that test file in mplayer, things got weird again. Here's the output from mplayer:

    Why the hell is it looking for pcmC0D0p?  It should be looking at pcmC0D3p.  Did it not get the memo from ~/.asoundrc?  Urgh.
    I've also tried '-af channels=6' in place of '-channels 6' but the same result happened.  It does the same thing without the '-ao alsa' option, I just specified it to trim down the output, so that I wouldn't be copying and pasting all kinds of other errors about not finding OSS or JACK or other things I don't have installed.
    If I symlink /dev/snd/pcmC0D0p to /dev/snd/pcmC0D3p, it'll fix the problem, but that feels like one ugly kludge.  I'd have to do it again over and over every time I reboot, too.
    Not sure if this would help matters or not, but if anyone knows how to change my card's device number from 3 to 0, I'd like to try that as well, but I'm not sure how to do that sort of thing.  I'm just guessing it might be worth trying, since everything looks for card0/device0 by default, and that kludge I tried earlier did have an effect, so maybe if we can just switch those device numbers with each other, everything would work smoothly without having to force anything through ALSA's configuration at all.  I believe card0/device0 belongs to the Host Bridge... is there a way to have them trade their device numbers for one another's in a safe manner?
    I can also get it to play if I specify the device like I did in my first test, using '-ao alsa:device=hdmi', but that defeats the purpose of getting good defaults set if I still have to set everything by hand before I play something.  If I try playing the test file without any options, like so:
    $ mplayer Nums_5dot1_24_48000.wav
    ... it will play, but only in two-channel stereo, and the parts that should happen in the center, rear and LFE channels get downmixed into the left and right channels.
    I can get it to work in aplay, though!  All six channels!  Not that I plan on using this as my primary multimedia software.
    $ aplay -c6 Nums_5dot1_24_48000.wav
    The only solution I found so far that allows me to have 5.1 audio by default is to install the PulseAudio server, which is able to find a sink/source named 'alsa_output.pci-0000_00_03.0.hdmi-surround' and lets me choose that as my default.  Only problem with this is that PulseAudio has its own problems.
    Aside from the crackling sound issues in some Wine games, Pulse also has a much bigger drawback -- a complete lack of passthrough support, meaning I can't use encoded streams such as Dolby DTS and TrueHD with PulseAudio.  I have a Harman/Kardon AVR and I'd like to get my money's worth out of it, so I'd really like to figure out a solution in ALSA without using Pulse at all.
    Does anyone know how I can have my cake and eat it, too?  I just need 5.1 surround, by default, in ALSA without PulseAudio.
    HUGE thanks to anyone who tries to help here.  This is really making me sad and frustrated, I've been using Arch for quite a while now and this is the first real big stumper I've come across that forced me to post a thread.  Otherwise I've been having a wonderful time.
    Edited because I tried something different that removed *some* issues, but the above problems still remain.

    Well, I thought I fixed it doing this...
    pcm.!default {
    type plug
    slave.pcm "dmixer"
    pcm.dmixer {
    type dmix
    ipc_key 1138
    ipc_key_add_uid true
    slave {
    pcm "hw:0,3"
    format S32_LE
    channels 8
    rate 192000
    period_size 9600
    buffer_size 38400
    ... but then realized it strangely makes applications that run at 640x480 have no sound at all.  No idea why the video resolution is screwing up the sound, but that's what's happening, because if I set the resolution any higher, the sound comes back.
    I'm going back to PulseAudio, I feel like ALSA is mocking me.  I wrote a wrapper script for the few times where pure, Pulse-less ALSA will be necessary for me.  Here it is, in case it helps anyone else.  I've tested it with XBMC, it turns off Pulse and allows ALSA to pass through encoded streams unhindered.  It also works with some Wine applications that have scratchy audio glitches in Pulse.
    #!/bin/bash
    echo "autospawn = no" > $HOME/.config/pulse/client.conf
    pulseaudio --kill &> /dev/null
    "$*"
    rm -f $HOME/.config/pulse/client.conf
    pulseaudio --start &> /dev/null
    I'm removing the SOLVED tag because technically I didn't resolve any of my original issues, I more or less gave up on what I wanted to do and found another way to satisfy my needs, but it still isn't as elegant as I had hoped for.  In any case, I'm done with this issue for now and the forseeable near-future, but if anyone has anything further to add, feel free.

  • Why doesn't the MBPr support 2560x1440 over HDMI with OSX when Windows7 (bootcamp) supports it just fine?

    I purchased a 2013 MBPr 15" (the first Mac I've ever owned btw) and so far have enjoyed the experience. I purchased a large 27" high resolution 2560x1440 non-Apple display which I planned on using HDMI output for, since HDMI has no problem supporting this resolution. After receiving this display yesterday I came to the sad realization that OSX does not support 2560x1440 over HDMI. However, under further investigation I found that Windows7 in Bootcamp on the same machine will beautifully display the full 2560x1440 over HDMI.
    This means that OSX is the problem, and not the MBPr since Windows7 displayed the full resolution with no issue. If the hardware can support it, why would Apple disable it in the software? Is this just their way of forcing people to use DisplayPort? Or is there hope for them fixing this in future versions?

    OK.  No reason to be playing games here.  Just surprised that this issue hasn't been brought up here on the community boards as well.  Here's the simple solution

    After reaching a Level III technician in Belkin customer support today and having spent approximately 4-5 person hours on this issue, we figured out that the Sound/Output preferences in the Apple System Preferences should not be set to "Internal Speakers"  but rather set to "USB PnP Sound Device". 
    Worked like a charm.  Simple, elegant solution to a real problem, one likely to be encountered by 90% of the people who buy a Belkin Thunderbid Express Dock off the shelves of any Apple Store to use with a current generation Apple laptop or desktop computer.
    But the Level III Belkin technician admmtted that this critical little piece of simple, straightforward information should have been readily available to their Level 1 techies who began helping me 5 person hours ago.  Would even have saved Balkin loads of customer service support time.
    And so the saga ends
    Belkin owes me for helping them learn this precious lesson.

    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!

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.

  • No sound over hdmi, ION2 system

    Hi there
    I'm trying to get sound output over hdmi connection without any success. I'm totally out of ideas as I tried it with openelec.tv and a xbmc live system. All the time I never heard anything. I tested with speaker-test and mplayer. I tried stuff from the guide here: http://breden.org.uk/2010/09/30/shuttle … ta-2-live/, http://www.nvnews.net/vbulletin/showthread.php?t=157347 and also from xbmc wiki:
    -different settings of asound.conf (however afaik this does not affect speaker-test -D plughw:X,Y -cN)
    -options for the snd-hda-intel module
    -unmuting
    -different input channels of my receiver
    -different nvidia driver versions
    Here are my specs:

    What I noticed is that dmesg does not show any hdmi hotplug event, something like: "HDMI hot plug event: Pin=5 Presence_Detect=1 ELD_Valid=0"
    So I thought maybe you arch linux people have some creative ideas what the problem is here?
    PS: It can't be the hardware because it works with windows7.

    .:B:. wrote:Does audio over HDMI work when the nvidia module isn't loaded? The 1st gen AppleTV has that issue, but I cannot imagine nVidia's ION platforms suffering from the same problem on Linux...
    No, does not work either... I need to help to figure out why the hotplugging and detecting of the receiver does not even work.

  • Sound over HDMI works halfway.[SOLVED]

  • 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!

  • Audio out from HDMI to TV cuts out

    I'm looking for help to troubleshoot the following problem:
    I have a brand new iMac, 27", i7 (my first Mac ever). Using the Moshi Mini DisplayPort HDMI adapter, I output video and audio to my LG 55LH90 1080p LED TV. Everything is fine except that approximately every 15 seconds, the audio will cut out for 2 seconds completely.
    The problem occurs regardless of whether the audio is from iTunes, YouTube, VLC, Quicktime, etc.
    Does anyone have any ideas about what could be causing this problem or how to fix it?
    Thanks

    I have solved my problem.
    After spending an inordinate amount of time trying to troubleshoot this (trying different cables, adapters, settings on my TV and iMac, different devices, scouring the internet for help, etc.), and with both LG and Apple customer service pointing the fingers at each other, turns out Apple was right (and LG was incompetent).
    The fix was simple. When I was about to give up, I played around with my TV settings one more time. I disabled the "Clear Voice II" setting on my LG TV and it made the problem go away. Audio is 100% fine over HDMI now. Hurray!

  • Audio out from HDMI port?

    I have connected my TV and Booklet via a standard HDMI cable.  This same HDMI cable works fine with my DVD player.   When I use it with my booklet, only video seems to be sent to the TV via the HDMI cable.  Is the HDMI out port supporting only video, or audio as well? I understand the booklet supports HDMI 1.2, which should support an audio profile, as far as I know.
    Let me know if you have been able to get audio to work over HDMI.
    thanks,
    John

    I found your discussion attempting to find the answer to the same question.
    I won 5 of these things at auction and wanted HDMI to be a selling point
    I researched far and wide and now I think I have the answer now.
    I had to reload the OS and  all the drivers for all 5 units
    I read some of the replies to this topic and with some people saying that they had audio and I didn't, I felt that either I was crazy or someone is not truthful. so i had a thought ,
    after about  the 3rd unit I tried to just try to hook it up to a TV bare without Nokia updated software
    What do you know, it worked.
    So I have come to the conclusion based upon using both units after testing them with and without the update, is with the stock driver provided, you will get the audio from the HDMI port; if you update the software from the updater(which I noticed it says the driver is MANDATORY)
    You will not.
    There is a plus and minus on both occassions
    With the graphics driver update you can scale your video once hook to an HDTV to full 1080p HD; but you wont get any audio (at least for now)
    Without the update you will get the audio out , however you will only get the same native resolution as the netbook 720p
    So contemplate which feature is more important you   and make your choice.
    Higher picture quality(full HD) with the driver yet I need 2 cable  (HDMI AND 2.5 to RCA)
    OR lower  resolution720p but audio as well
    I hope this helps but i see my next challenge for both you and is to see if we can roll back the driver if we want audio over HDMI.
