Front and rear audio not working only from internal speaker

[freakadell]

I installed 2008 R2 on my HP Dc7100 and almost everything is working.
The problem i am having is that i found a driver for audio and it installs ok, but the audio is only coming from the internal speaker. Front and rear audio jacks are not working.

Have searched the web and this forum.
Anyone has any ideas?
Thanks

Sounds to me like a wrong device is configured as the default audio output.

Try one of the solutions halladayrules proposed in a similar post: [localurl=viewtopic.php?p=7463#p7463:1qnzop2l]Win2008Workstation Forum – Sound disturbances[/localurl:1qnzop2l].

Hope one of these solutions helps you too! 🙂

I have created a video tutorial on how to change your default sound device on YouTube. Be sure to read the description for further details.

P.S – Arris, do you like my idea of video tutorials? I’m not sure if you can embed youtube videos on this forum or not can you possibly add that feature or show me how?

Hi,

Thanks for your replys and suggestions, i have tryed all of those but nothing changes.

Is there some registry keys for enabling /disabling rear and front audio jacks? Because it seems like windows does not know that there is those jacks present.
I am thinking to install Win 7 x64 on same hardware and see if its possible to get working driver from Windows Update.
Or is there a way to fool WU that i have Windows 7 instead of Server 2008R2?

One other thing i noticed is that Mic works on the front panel. So there is just something missing somewhere. In the registry maybe.

It might very well be an incompatible driver even though its properly loaded. Have you tried flashing your bios to the latest possible version to see if that helps? After flashing your bios try to run Windows Update to search for your audio driver.

Here’s a video tutorial I made on how to enable driver search through windows update. It’s Server 2008 but its located in same exact place on R2.

It sucks your chassis is small form factor cause you pretty much gotta have a low profile card to be guaranteed to fit in your machine. It might not matter even if you purchase a budget PCI sound card. Some of the budget priced ones pick up too much static sound, even more than your integrated solution!

There is actually a raiser card available to install full size PCI cards, but then i only have room for two, right now i already have second nic, Ati graphics and SATA raid controller.

I could use the graphics card via HDMI and get sound but i havent got ATI CCC fully working, the display has black border around the edges of the screen.
For now i made myself an usb soundcard using broken Logitech headset 😀 . And it sounds actually better than the onboard audio. So i am happy for now.
Still would like to get everything working and i think next step is to install Win7 and see if i get sound working with windows update drivers or with some others.

Well well well. I finally managed to get the audio working with DC7100 onboard soundcard.
From dev manager i took the hardware id and googled it which lead me to some Dell x64 compatible drivers. Windows ofcourse warned that this driver is not compatible but it installed ok and audio is working as it should.

And the issue why the sound didn’t work before because there is a registry key that should have audio jacks configuration in it. The previous driver that i used did not have the info how to add all thats needed.
For my pc it was HKLMSYSTEMCurrentControlSetControlClass{4D36E96C-E325-11CE-BFC1-08002BE10318}007Settings.

Maybe thats useful for someone, but for me Server to Workstation conversion is now complete.
