    Have installed Windows 2008 R2

    Can anyone please guide me to a working drivers for Dell Soundblaster OEM 5.1 PCI Sound Card.

    I have searched around a lot and still not able to make it work.

    Thanks for all the co-operation

    Arris: Have you tried to find your PC at the Downloads & Drivers section at the Dell website and download the Windows 7 drivers with the right architecture (x86 / x64)? If you did, read the Drivers in Windows Server 2008 R2 page or ask your question at the forums and add some more info about the device which can be found in the Details tab of the device in the Device Manager (devmgmt.msc).

    Thanks a Ton Bud. worked for me 🙂

    Thanks very much mate. You rock

  4. Bryan Price says:

    (Now I read what Tom says)

    14 is 20 in hex. If you’ll notice the default is 64 hex, 100 decimal.

  5. Bryan Price says:

    Thanks Tim for that bit on configuring the sound.

  6. Tom says:

    The default SystemResponsiveness is 100. It looks like your reg tweak will set it to 14? Is that correct?

    Or does your tweak make it the Vista default of 20?

    If you are having no audio
    – with a RealTek integrated audio card,
    – and your headphones / speakers are plugged into the front jack
    – and your audio works when they are plugged in at the back

    try disabling Front Panel Jack Detection in the RealTek HD Audio Manager. Click on the Folder icon in the main screen, on the right side, under the Advanced Settings link. Check “Disable front panel jack detection.”

    Take all of your volume settings down to a reasonable level. Try your audio program again.

    I have the same issue as Kevin. Did the stuff on the audio page and at first I got sound, then after a reboot I lost the audio device (speakers?) and now I ony got SPDIF device which I can’t use =/ Does anyone know how to fix this?

  9. Kevin says:

    I have server 2008 running on HP DV4-1275mx with no audio from speaker but headphone works. There are 2 playback devices, Digital Output Device (HDMI) and Headphones. There is no speakers device. What did I miss?

  10. Kal says:

    I found audio was choppy/stuttering… it turns out that Windows 2008 uses different priorities for task scheduling…

    The following registry entry is set to 100 in Win2k8, where it is set to 20 on Vista.
    HKLMSOFTWAREMicrosoftWindows NTCurrentVersionMultimediaSystemProfileSystemResponsiveness

    for more details.

    Arris: Thanks for your explanation! This tweak has already been added to the Registry Tweaks page and a link to the tweak in step 5 of the Enable Sound Acceleration article.

  11. Jonathan says:

    I’m posting this here, if you have problems with sound you could try this registry hack.
    Right click > Merge.

    What it does is what a Microsoft employee described on a forum.

    I don’t think it can harm your computer, but use at your own risk.

    Neither did I have any sound.

    Sound acceleration and the like were enabled.
    All drivers were correctly installed.
    No problems were to be identified in the device manager.

    The funny thing it all worked AFTER I connected headphones to my laptop.

  13. Marty says:

    Tim,

    Thanks for the tip, that is exactly what I needed, and I’m glad I finally found it here in your insightful comment.

  14. vmlinuz.exe says:

    I recommend against changing the DEP settings (I also recommend not to buy creative but hey ;). You could at least add an exception to the faulty image so the other programs are still protected. I’ve had to do that for printer drivers :p

    Arris: You are right about that! From a security perspective it’s better to leave it enabled. However, if you get the ‘DEP Problem’ with many applications/games it’s more simple to just disable it at all.

  15. Tim says:

    Sometimes people may want to use Remote Desktop Connection to their WS2008 box and have the audio redirected to the system from which they are remoting. By default, WS2008 comes with the ability to redirect the audio over RDP disabled. Here is how to enable audio redirection:

    start > run > tsconfig.msc > rdp-tcp > properties > client settings > uncheck audio > ok

    You need to logoff/logon to enable this change.

    Arris: Didn’t know this trick! Thanks for your comment, Tim! 🙂

    I also have no sound :[

    Arris: You can create a topic in the Drivers Compatibility section at the Forum with information about the hardware and OS you are using.

  17. Brent says:

    To anyone reading this, if you have this problem, load the motherboard driver for the audio in xp and it should now say Intel Integrated audio in device manager. Update the driver to the one on the intel cd and you should be all set.

  18. Brent says:

    I have no sound also, anyone figure out a fix to this? It is on an intel board with 845 chipset. AC ’97 also.

  19. Dave says:

    Followed all the instructions here, modified DEP, still can’t get my AC ’97 audio working. The driver installed, the mixer is working, but no sound

  20. Adrian S. says:

    Maybe You should add to Your excellent guide that Win2008’s DEP-Setting causes Creative Audigy to fail partially (no appropriate mixer devices are created). DEP should be set to the same value as in Windows Vista. After setting it correctly everything installs just fine.

    Arris: Thanks for the tip. The article about setting DEP to the same value as in Vista can be found here.
