HDMI sound output works just fine, audio jacks not at all! New PC

Hello everyone, you guys seem to know your stuff so Ill ask for your help:

I have a frustrating problem with my brand new XPC Shuttle computer. Everything works fine, just not sound. I tried hooking up the computer via HDMI to a TV for the first time as I didnt have a monitor - sound works just fine. Then later I removed the casing and installed 4 more Gbs of RAM for a total of 8. In order to do this I had to remove and reinsert the videocard. Computer was never on during that procedure.

Now, I cannot for the love of God make this computer produce sound trough the (correctly) connected audio jacks while it is hooked up to a proper pc monitor - Ive tried with numerous speaker/headphone devices which all are in mint condition (confirmed with other devices).

My OS is Windows 7 Home Premium 64 bit. In the sound manager down in the corner it said at first only "Realtek Digital Output". I figured this could mean that somehow, using HDMI cable (as it was the first monitor I used the system on) that the system defaulted on a HDMI output for sound. It would not show bars for anything else, and Speaker/Headphone devices were listed as "not connected" - despite clearly being so. It seemed at first like a problem with drivers - classic stuff. Please dont go there: Drivers are installed, up to date.

Then I launched Realtek HD audio manager and checked the box "Disable front panel jack detection" - as instructed by the program in case I had problems with detecting devices. Now the soundbar is moving vividly on screen as I play on some "virtual" version representation of a headset. See picture.

But the problem persists. Ive seen numerous similiar problems online, but none where HDMI output were fine. I have not been able to go trough BIOS and find solution there as I couldnt find an option that was related to sound as far as I could see.


Any help would be greatly apreciated!

Best regards, Lars

My problem seems very similiar to this gentleman's:

He seems to not have found a fix to his problem too. About my system: Could you guys look at the pictures attached to this post?

Thank you so much for any insight or help!

Update-different fix attempts, but still not working

I checked the following:

- BIOS: on-board sound enabled
- Service.msc windows audio automatic start enabled
- Realtek HD audio manager: box "disable front jack detection" checked (recommended in case windows wont detect audio devices)
- Drivers up to date and running
- Clean install of Windows Ultimate 64 bit, did not resolve the problem

Anyone had a similiar experience, or know what could be the problem?

I would say enable jack detection.
Set the default to Speakers. Unplug the speaker cables.
Plug in your speaker cables and see if the jack detection pop-up appears.
Press OK to the prompt.

If no jack detection appears, unplug the cables, restart your computer and try again.

Hey p5bdkw,

Il try that, getting back to you in a second!

1. When i enable jack detection, the speaker symbol appears as not plugged in, when I enable it it says that the device is connected - regardless to if the speaker/headphone is connected or not.

This to begin with seem a little counter-intuitive to me, but Im going to go ahead with your recommendation anyway.

2. When front jack detection is enabled, the speakers are not detected (this situation persists if I disable front jack detection, it seems as if windows just "makes up some sort of imaginary device" when I disable front jack detection.

3. Unplugged everything, restarted, no improvement.

Thanks for your attention though, any other suggestions?

I take it you're getting no front panel jack detection.
Are you getting back panel jack detection?

The reason I ask is that....
1. The back panel is connected directly to the motherboard and should work, unless the board is faulty.
2. Front panel connectors plugged into the motherboard can be problematic and sometimes don't work at all.

So if your back panel detection works, then that's good.
If it doesn't, then that's a problem if neither the back or the front connectors work.

Thanks again for coming back to me, greatly appreciate the effort. Im afraid that neither the front jack nor the back works, it just wont detect the audio device. Though I left out one interesting detail that could help:

When a headphone is connected to the front jack, the right earphone will produce an annoying rather loud electric noise or interference, this does not occur with the back one. Maybe the front one is faulty and somehow some sort of electrical conductance problem is impairing Windows in registrating the audio devices when plugged in or not? Im just guessing at this point.

Thanks again for your attention!

Hey again, now I droned trough the forum and found this thread: http://www.sevenforums.com/graphic-...-geforce-gtx-460-has-disabled-my-sound-2.html

I would seem that my Graphics cards (Nvidia GTX 570) built in soundcard, which is only enabled in HDMI mode (hence my audio only works in HDMI mode) completely takes over and disables the on-board sound. This is the most reasoneable explanation I can find right now, but the strange thing is that in BIOS I have confirmed that on-board sound is enabled! :S

Could that be the problem? That HDMI audio driver of graphics card overruns the sound driver of mobo?

Update:

A person on the above forum listed the following possible options:
1. Get a dedicated soundcard to override the video card driver - impossible to me as I have a small box (Shuttle)
2. (see picture) Disable the audio channel with the same bus as the video card, in effect disabling the overriding effect of the video card. Tried that, no fix.

Are your drivers up to date.

As you can see they are both from august this year

Im pretty sure its the graphic cards audio drivers, related to HDMI use that somehow have impaired the mobo sound drivers. My question now is really how to make the mobo drivers override the graphic card ones?

Ive tried removing the NVIDIA sound drivers and the related Audio services which use the same bus as the graphic card - thought that would "block" them. I just played Elder Scrolls IV: Oblivion on my tv-monitor and the sound worked perfectly, but the ability to simply play the sound trough speakers still are not available to me. Ive droned around the web, and it seems a rather common problem, at least not very rare.

surely there must be some way to fix this?

Thanks again for your time!

This gentleman have the same problem as I: http://www.sevenforums.com/graphic-cards/64554-graphics-card-upgrade-2.html

On bottom of second page. Now, I have on-board audio as enabled with my BIOS - (the auto function is not available to me, only enable/disable) what can I possibly do??

I would disconnect the front panel connection to the motherboard. It may be defective.
After disconnecting it, unplug your back panel speaker connection. Plug it back in and see if you
get the Realtek jack detection pop-up. If you do, see if the Speaker says "working".

Its 4:35 AM here in Norway now, have flipped my day-rhytm 2 days in a row now to fix this, Im just going to to reinstall the video-card and realtek drivers and drop of the faulty piece of annoyanc (aka computer) off at a repair shop as you are probably right, it seems to be a fine combination of the: as some guy said at another forum: "I think the graphics card has somehow confused the PC into thinking it had another sound card installed."

And some form of mechanical issue.

In a last ditch attempt I uninstalled anything NVIDIA, together with all audio drivers and teared the video card out of the machine to no use - the sound didnt return.

Someone came up with the idea that the graphic card were to power draining so that power to sound were cut but:
Though, as I mentioned earlier there was still static noise in the jack when volume slider and volume knob on speakers were turned all the way up - and i have a good 500W PSU, so I have plenty of power supply.

Thanks for your time. Best regards, Lars

Hi Lars (I guess this is your first name...)
Believe it or not, I have suddenly the same problem after my power supply had to be replaced. And I also have a Shuttle with a graphic card.
If by any chance you come across this thread (long time passed since you posted yours) -please let me know if the issue was fixed.
