The speakers stopped working a while back and I can' figure out why.  This is for an HP desktop (a6750y) running Windows 7 Enterprise.

A USB headset works fine.

But the speakers don't work, I plugged the sound jack into the green slot both on the front and back of machine - no luck. The speakers do work, I tested them out in a different computer.

attached is a picture of the properties, and when running the test, the green bars went up and down.

I've looked at everything, need some tips !

Are these the internal speaker on a desktop box (built-in, internal)?  It maybe as simple as the speaker being knocked loose.  If you have some cheap speakers that you can plugin to the headphone jack on the front then the back..

If another tech or a user added a component to the user's computer is probably why this has occurred.

i'd go for something being mute. sound cards handle multiple channels and each of them has volume control. first thing is to dig into the sound mixer : this is most likely not a hardware issue.

did you test using the same application that worked with the usb headset ? like above different applications use different channels (ex : pcm volume control only affects some of them).

can you try to run the builtin speaker test ?

does the internal audio system work ?

right click on the speakers, and select properties
in the level tab, check if the level is high enough - and enabled


also in the sound window you posted, selct the sounds tab, and select  windows shut down sound then hit the Test knob to hear it

- not sure what you mean, I don't think there are internal speakers for this desktop, you have to have external speakers.

- I checked the sound mixer, at it's set properly

>>did you test using the same application that worked with the usb headset ?
- yes, same youtube video

>>can you try to run the builtin speaker test ?
- yes, isn't that what I posted above (screen shot) ?

>>does the internal audio system work ?
- not sure what you mean . . .

nobus,
- I checked the level tab, it's high (~85)
- tried the sound tab, nothing . . .

I'm going to re-install the audio driver.

If at all possible, can you Resore the System to an earlier time it worked for me.

I uninstalled the Realtek driver, and now I have sound !
- but now I have four sources ???
speaker sources
In the attached, they have the wrong icons, so I switched.

I'll leave well enough alone and not install the driver from HP.

weird enough. seems that the reinstall made it detect new channels properly : namely the headphones which are likely actually the speakers. maybe the install of the usb device is what produced the initial mess. if you happen to reproduce, i'm interested into what produced this in the first place.

it looks like you installed the wrong drivers before

did you get them from HP ?

I re-installed the Realtek driver, and then it stopped working again ! The version was the same as before but the date was more current, so I thought I'd give it a try. But apparently HP and this driver don't get along.

My PC is about 5 years old and runs Windows 7 Enterprise, originally it was Vista.

Here's the driver:
realtek version

everything good now, with Realtek driver installed (plus it helps when the speakers are plugged in . . . )

thanks for the tips.

thanks for the assistance. I then installed the Realtek driver from HP support site, and it's working now.
