    If you have multiple PCI-Express slots (ie If the one PCI-Express slot is already being used by Video)
    Newegg again?
    Newegg Newegg Newegg, I've never seen more links to the business from anyother tech forum. It's all over the place here, (even I post links now)
    I think they should hand us out freebies for all these links

    There is 2 pciE slots in the x1200, What would you be using 2 half height pciE slots for?

    I like newegg, Descent prices, Ok support, and good product selection.

    Since Fry's has a good return policy I decided to go out and pick one of those X-Fi Surround 5.1 USBs up. Plugged it in, didn't have to install anything and now I've got 5.1 optical out (including DTS) running into my receiver. So, if you're looking for SPDIF from the Acer in Vista 64 in an easy way this seems pretty good.

    Hey, just posting to say thanks to everyone who helped out in this thread. I noticed the post from chuckster pointing out the new BIOS, I installed it, and everything is working great now. I'm still a bit upset at Acer's lack of good tech support, but at least they finally got around to fixing the problem.

    I installed this bios update last night to get my audio working and it works but very briefly. Windows boots gets me to the login screen I hear sound and before I can even login my screen goes blank. Tried switching ports on my TV haven't tried another cable yet but I will tonight. I didn't try the HDMI before the bios update because I new the sound was broken.

    Any other ideas?

    Go to safe mode (repeatively press F8 function key on Windows startup)
    Select the Safe Mode option
    Log into your Administrator account

    Once in safe Mode, (Yes) select:
    Start->Run-> Devmgmt.msc ->ok

    Once Device Manager opens, select the + sign on Display Adaptors
    When the submenu opens, showing your installed Video card...
    Right click on it, and select Uninstall (or remove)
    Once the process has been completed, restart normally

    In Normal mode, you will need to load your Video drivers again

    Any further help, you should create your own thread in Audio and Video, stating the fault, and what you have done.

    Well I went into the bios and disabled HD audio and that takes care of the HDMI display going off. Unfortunately this also kills all audio.

    I will try the safe mode suggestion....

    Not sure why this should be in another thread this thread is pretty specific to the X1200.

    So I just picked up this system that was bundled with the 22" monitor since I needed another one anyway, and after reading through this thread, I am wondering if the audio will work if I just run it through the TV speakers on my Panasonic plasma as I don't have a home theater system hooked up to it. I saw a post in this thread that made it sound as if this would work. If not, then I assume I can just use the standard audio out with an RCA cable to input into the plasma.

    I hooked up the X1200 to my Panasonic plasma and it looks great but there was some overscan so I will have to figure that out later. For now I just used the NVIDIA screen adjust tool to get it to look right.

    I was hoping that I would have the latest BIOS update since there was a big sticker on the box stating the BIOS info, but I didn't so I will try the new one from the link above. I am hestitant to flash the bios on a new machine though but I do want the HDMI audio to work so I guess I will have to suck it up and do it. Any suggestions on the best way to go about it?

    So I hate to be "that" guy that resurrects a dead thread with his first post but I have been Googling, reading, and re-reading this thread as well as every other relevant page and forum regarding this issue.

    I have the latest BIOS installed (the one that everyone claims HDMI audio works and has LAN stability). And I have the latest Chipset and Graphics drivers from nVidia's website... I think...

    The one thing I've noticed is that in Device Manager>Display Adapters, it says I have the GeForce 9200... These machines have the 8200...

    Also, in the sound devices, I have a Realtek HD Audio Device and an nVidia HD Audio Device. However, the Realtek device is the only one that I can control in the volume controls. I've tried disabling it but then I have no volume controls. At least, there is no audio device according to them.

    Any ideas? I'm running XP SP3 if that helps at all.

    Thanks in advance.

    djg08642 - No need to worry about being 'the guy'. I hope I can help. I have been helped many, many times on here. I am glad to try and return the favor....

    I don't know why it is showing up as 9200, instead of 8200. I also have all the latest drivers and mine says 8200...strange...

    You have to use the Realtek Device Manager to select the NVidia HD audio device.

    You need to use the NVidia HD audio device instead of the Realtek HD device, but still use the Realtek Device Manager.

    I am at work right now, when I get home later today , I can post the exact steps.
    Its a real pain to get it working the first time, but after that it works ok.

    It should show up in the list of devices from the Realtek Device manager.

    I looked everywhere in the Realtek manager and didn't see anywhere I could select a different device.

    Step-by-step instructions on how to get this working would be much appreciated :)

    EDIT: Just downloaded the latest Realtek Driver and I see where to select the output source but the nVidia HDMI device isn't listed. Just the Realtek one. Help!

    I am having the exact same problem djg08642 is having, even where the card shows up as a 9200 with the latest drivers.

    In my case, the awdbiosa02 fixed my HDMI audio issue to where I could actually boot windows Vista 32 and hear a sound for 2 seconds and then nothing....however when I go into my XBMC and run a movie, the sound works flawlessly over hdmi. Also, my network works perfect, no issues at all

    There is 1 issue and 1 issue only with the A02 though. With the A02 bios, my computer has a problem booting and ALWAYS makes me select F1 to start up...and WILL NOT LET ME IN THE BIOS!! If I hit Del to enter bios at any point, i just get a black screen forever...

    If I load the latest bios, everthing works perfect EXCEPT now no HDMI Audio.

    This is driving me crazy! I have yet to play around with the A03, but the first time I loaded it, it didnt work....

    Okay I reloaded the entire system with the A02 bios and Vista 32 Home Premium and had no sound. The sound devices said High Def HDMI - working. But it really didnt work.

    I stumbled upon an NVidia HDMI Audio Driver...the only ones I could find were for XP 32 and Vista 64. This was on web site. So I tried the XP 32 version of the driver and after it installed, Vista said there may have been a problem with the install, would I like to find a solution, or 'the driver installed correctly'. So I chose installed correctly and rebooted. Went back in to sound devices and noticed now I have 'NVidia HDMI Audio - working'

    Now please note, I have no sound in windows itself, but when I load XBMC and tell it to use 'NVidia HDMI Audio' in Audio Hardware in settings, I then play a 720p mkv movie and I have 5 channel sound over HDMI! :)

    Thats all I really care about. So the bottom line is, the standalone NVidia HDMI Audio driver solved the issue.
