Sometimes no sound with HDMI under Windows 7

I'm running bootcamp with windows 7. After booting windows on the mac mini 2010 there is no sound via HDMI. After rebooting the system with mac os the HDMI sound works. After bootin windows again the sound works in windows too. When I shutdown windows and switch power sound is off again.
Maybe its an issue with the nvidia audio driver in windows 7?

Same problem here. Did you ever figure it out?

HP 2311xi Monitor not working with HDMI? - Windows 8

I have my RCA 6ft HDMI cable plugged into the back of my computer, and running to the back of my monitor. I can see my background, and the bottom tab showing files, internet, etc. But nothing else. No time, sound, or date in the bottom right corner, and all my programs are missing. I have to switch back to DVI for everything to work. I am confused how I get connection with HDMI, but my programs are missing? - Please Help

I understand things aren't quite working as expected with HDMI and the 2311xi monitor.
Is the monitor being connected to a notebook or a desktop PC?
What model is the PC?
If it is an HP PC, what is the product number?
As far as sound goes, have you verified in the sound manager that the HDMI port is selected as the sound output? Sound may still be defaulted to the analog sound output similar to when DVI is used.
Go to Start, search for Sound and open the result under Control Panel.
Verify that HDMI is selected.
if HDMI, or the monitor is not listed, then let me know what options are available. You may need to right-click and select show hidden/disabled devices.

Acrobat reader X with thunderbird under windows 2008 server

Hi,
i use acrobat reader X under windows 2008 R2 . My Mailclient is thunderbird.
I get an error when trying to send an E-Mail. "Acrobat could not get a connection to your e-mail programm".
I defined thunderbrid as the standard mailprogramm under START->CONTROLPANEL->STANDARD-PROGRAMMS
I already tried to google the solution, but the only one i found was for Windows VISTA and Windows 7. There, you have not only to define the STANDARDPROGRAMM, you either need to make a change on "default programms and computerstandards" which is missing in windows 2008 R2
Can anyone please tell me how to use acrobat with thunderbrid in a windows 2008 environment????
Thank you

Hi Michael,
sorry for using the wrong forum. I'll post my question to the Reader board ...
To answer your question. That was my idea too, but it is not possible to copy a whole profile. They are a lot of other problems if you do that. I didn't find the settings only. may it would be enough to copy the settings for the reader.
Best Regards,
Markus

D2kwutil running with Forms6i under Windows XP

Hi
I'm trying to run D2kwutil.pll version 6.0.6.0 with Forms6i 6.0.8.8.0 under Windows XP and it's not working when I try to call WIN_API_FILE package. I tryed to run the demo form (WAPIDEMO) that I downloaded with the PLL but they don't run either - As a matter of fact, this form don't open.
Does anyone know what can I do to solve, I mean, to run this PLL under Windows XP - if it is possible?
Thanks

How can anyone help if you don't describe the problem? Saying "it doesn't work" is of no value whatsoever.

Forms Product Management Not to be critical or anything Robin, but publicly berating and humiliating your customers doesn't help anyone either.
This is especially true when its obvious from the name and the return email address that the person is Brazilian and is at least making the attempt to communicate the issue in English. Would you have understood their problem better if they'd used their native tongue? Obviously something didn't translate well - and it came accross as "its broken".
And by the way, the customer did describe some of what was wrong... they attempted to open a specific demo form, which came bundled with the PLL file from YOUR company, and it wouldn't even open. They are running XP and Forms 6i, which as far as I last knew was not a certified product combination (which is likely part of the problem).
A little effort (and a kind word) might go a long way toward finding a solution. And if you're just burnt out or having bad day, try to remember that its not OUR fault.
With all due sincerity,

Enabling EAX tm for Sound Blaster ZS under windows 7

My sound card used to have EAX support under windows xp 32-bit, thus I could enjoy that choice of noise within video games. Now the options in video games tell me that I don't have that EAX capability. I'm rocking windows 7 32-bit and don't know what to do for this [email protected]

You install Alchemy yet for those DirectSound3D games yet? Even better use this,

I can't read Nikon D5200 Raw NEF files with CS6 under Windows 8.1?

I bought a new PC so I could use Photoshop CS6 more efficiently. However, after I installed CS6, I can't read Nikon D5200 Raw NEF files under Windows 8.1. I've tried updating CS6, but nothing seems to work.

First, I hadto load the most recent version of the Adobe Application Manager. Then I could see all of the CS6 Updates including the most recent Camera Raw update.
I had to run one update at a time for it to work correctly.
But now I'm cooking with gas.
Thanks for your help.

Problems with GUI under Windows-NT

Hi friends,
I've created a Java-Application which works fine under Windows 2000, Windows XP, Linux and Solaris.
The only problem I have is with Windows NT.
When the application starts, the window will open but doesn't display any content. The application is
working (as I can use keybord-input, keybord-shortcuts and so on), but no display besides an empty
window...
I tried different Look&Feels, but no change....
Do you have any ideas what could be wrong?
Thanks a lot,
Chris
P.S.: JDK is 1.4.2_04

MSI FM2-A75IA-E53 : No Sound with HDMI

Hi,
I recently bought a MSI FM2-A75IA-E53 for a media PC , installed Windows 8 and after a lot of hassle finally have everything installed...everything works great except I can not get sound through the HDMI port. Windows shows that the HDMI audio is disconnected (cable not plugged in) even though the video works fine through HDMI....just no audio!
I have installed and removed the Realtek HD Audio drivers, as well as the ATI HDMI audio drivers numerous times, in various order and my HTPC does not recognize that I have HDMI sound at all. The only thing that is enabled is "Realtek Digital Output" which corresponds to an optical jack that isnt even connected.
I have also tried to disable the HD audio from with in the bios to see if that would default to HDMI but alas, still no success.
I recently utilized a trinity APU to update my bios to 2.0 and finally installed a richland APU (A6-6400K) if that makes any difference.
Any Suggestions? I am at my wits end!

Thanks for the reply Flobelix, but I am not sure that is the case for two reasons:
1) I definitely have an additional audio device that appears under my device manager that accepts the ATI HDMI Audio drivers, and displays them under sound devices. Even if I don't install them, windows identifies an additional audio device it determines as HDMI sound as well. I can also disable the Realtek Audio within the BIOS options and I still have an additional sound device which windows recognizes as a HDMI audio device.
The problem is that windows just doesnt recognize that it has a physical connection.
2) On the FM2-A75IA-E53 webpage (....msi.com/product/mb/FM2-A75IA-E53.htm) they even advertise their HDMI v1.4 as:
HDMI v1.4 (AMD)
HDMI (High-Definition Multimedia Interface) is new generation fully digital video/audio interface which can transfer 1080p High-Definition video and Audio output in single compact connector. Supporting HDCP copy protection such as Blu-ray Discs, HDMI provides you with the highest-quality home theater experience.
Features
- Next-Gen Multimedia Interface
- Deliver Full HD Video & Audio output In Only One Cable
So I would assume this motherboard does indeed support HDMI audio.
Has anyone else encountered this problem with this board or a similar MSI board?

the ^CAborted by signal interrupt is because I ctrl c ended it because it wouldn't play the sound, it would just hang forever. It works with my Logitech Headset though. I'm running gnome 3 and the latest proprietary Nvidia drivers. Funny thing is I had HDMI running flawlessly through MATE a few days ago before the OS crashed and I had to reinstall. Any ideas?

so i installed the latest beta drivers and now pavucontrol is atleast showing that sound is coming out/trying to come out of the device. still no audible sound though.
i can't get aplay to get any sound out of my headset anymore though... but my headset is still working just fine in pulse. any ideas?
edit:::so I completely removed my de along with xorg, pulse, alsa and everything.. basicaly back to a square 1 arch install, and installed mate from there.... still having the same problem...
could it be a problem with the latest kernel update? it was working on an old install a few weeks ago on the older kernel. i don't remember going to all this trouble to get hdmi sound last time.

5.1 Sound via HDMI in Windows 7

Hi there,
I have a MBPr and have got the sound working via internal speakers and also can get surround sound via the optical connection. I'm trying to get surround sound working via the HDMI port though, but so far have had no luck.
The system reports that there are only 2 channels available via the HDMI. Orginally it had them listed as nvidia HDMI Digital Audio, but after me messing around it's just labeled as generic HDMI Audio.
Has anyone managed to get this working correctly? If so which drivers are needed as Windows just installs the generic ones. I've tried the Cirrus Logic and also the nvidia drivers, but they aren't recognised.
Any help would be appriecated.
Thanks.

I tried the solution in the wiki. The sound would work when I issued the aplay command, but then when I set the .asoundrc file, sound would not work (after logging out and logging back in). I also tried this solution from another thread, but I mistakenly forgot to make backups of the two respective files and now I have no sound at all. Help would be much appreciated! Thanks!
Edit:
Also tried this, didn't work either.
Edit2:
Finally got it solved! All I had to do was go into alsamixer and unmute the "S/PDIF" channel, follow the instructions from the wiki (see link above), and I finally got the sound to work.

HDMI no sound with Windows 7 upgrade

I am unable to get sound with HDMI , but visual is working, after upgrading from Vista to Windows 7. G70 series laptop, s/n 2CE92870KS.
Under control panel/device manager/display adapters, what is listed is mobile intel (r) 4 series express chipset family.
Under control panel/device manager/sound video games, what is listed is coexant high definition smart audio 221 and intel high definition audio hdmi.
Under control panel/sound/playback, what is listed is coexant high definition smart audio 221.
I am floundering greatly trying to figure out why the intel high definition audio hdmi is not listed under sound/playback. I would greatly appreciate any help. Thanks

Hi Jim,
Try this to see if it helps. Download the Chipset driver and Graphics driver on the links below and save the installers to your Desktop.
Chipset
Graphics Driver
Next, in Device Manager, open Display Adapters, right click on the Intel graphics chip and select Properties. Click the Driver tab and then select uninstall. When done, do the same for the for the Intel High Definition Audio Codec found under Sound Video and Game Controllers.
Now return to the Desktop and install the Chipset driver and then the Graphics driver. When complete, reboot the PC and see if this has helped. Check in Device Manager that both the Intel Graphics and the Intel Hi Definition Audio codec have reinstalled successfully and whether you now see the HDMI Audio option under playback devices ( found in Control Panel, Sound ) as shown as the top option on the screenshot below ( ignore the fact that it's ATI, i just mean the TV icon option ).

If it shows up correctly, try the HDMI connection and see if it now functions properly.

Microsof VX 3000 or 6000 Webcam does not work with Lync 2013 under Windows 8.1

Hi,
The problem is that i cannot use the Microsoft VX-3000 or VX-6000 with Lync 2013 under Windows 8.1.
If i go in settings under Video i can see the preview from the webcam just fine, so it works there no problem.
Wenn i try to enable my camera in a conference it does not work, i get an error: Your video cannot be started.
Now, there are no Windows 8.1 drivers for the Webcam so i installed the latest Windows 7 drivers. Because of that this webcam does not work with apps, that is fine i understand the driver problem and the way the new apps work.
But this Webcam works with skype under Windows 8.1 and it works with Lync 2010 client.
The same Webcam works just fine with Lync 2013 under Windows 7.
Is there anything i could do so that i get this Webcam to work with Lync 2013 desktop client under Windows 8.1?
Thanks

Hi,
According to your description, it may be caused by driver.
You can try to install the latest version of Display Driver to fix the display issue.
Since there is no driver for Windows 8.1, I suggest you wait for updating.
You can also post a case on Windows 8 forum, thank you for your understanding:

HT3986 I have a Macbook Pro, have recently upgraded to OS 7, have installed the bootcamp option, and am not getting any sound with using windows applications.

I am getting no sound with I use windows programs on my Macbook Pro. I am operating with the bootcamp option. The sound works fine with I am running the MAC OS 7
I read that my problem could be a driver, but I am unsure how to get this driver and how to install it.

Read the Boot Camp installation guide http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.7.pdf. You download the drivers during the installation process. Then you install the downloaded drivers after booting into Windows. You can also go to the source to get the sound drivers for your comuter. Search this forum and you will find posts with the url from which to download the drivers.

Error 2048 under Windows 7 64bit when opening DNxHD .mov

Hi people,
i'm experiencing a weird problem while trying to open a DNxHD encoded .mov file with quicktimeplayer under windows 7 64 bit.
getting the error 2048: "Couldn't open the file because it's not a file that QuickTime understands."
filesize is 5,6 GB and im running Quicktime 7.7.5, the file was encoded using avid media composer.
Other (smaller, around 2GB) files from the same source and using the same codec will play back fine!
This file is running fine on my macbook (10.8.5), but will fail to play under windows 7 bootcamp or on my PC.
I've read about filesize-limits around 4 GB, is there some truth to that?
thanks for your help
EDIT: i need to be able to play back the file with quicktime-components (not vlc or something like that) because im working with protools, which is using quicktime for video-playback.

Thanks for your reply nyc.
But the code i copied is in fact an extract of the USBDescriptors.c present in this directory.
If I try to execute this example, the result is the same.
