I went to a surplus store and got a good deal on an HP Compaq computer. I think it's a 7200.

 

Anyway, it's an older computer I got for my children. Everything runs great and we're learning how to use windows 8.1, with one exception. There is no sound. The little sound icon at the bottom of the screen says no speakers or headphones detected.

 

I've made sure the onboard sound is enabled in the bios, but the only sound driver appears to be an HDMI audio driver, which I think is coming from my video card (Because it's the only thing with an HDMI port) but my monitor and video card are not hooked up through HDMI and my monitor is not HDMI ready.

 

How can I get Windows 8.1 to recognize the onboard sound/audio? I downloaded Belarc Adviser to figure out exactly which motherboard I had and went to the Compaq website and they had drivers for just about every OS except for windows 8.

 

Can I download the Windows 7 drivers and use them? Or is there another work around so that I can use the onboard sound device rather than getting a new HDMI monitor with sound?

 

Thanks,

Most driver from windows 7 are compatible with windows 8.

You can give it a try.

 

Thank you.

Thank you for your advice, Sirawit.

 

I tried going here:

 

http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome/?sp4ts.oid=3459245&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3DswEnvOID%253D4059%257CswLang%253D%257Caction%253DlistDriver&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken#Driver - Audio

 

And downloading two different windows 7 drivers. The 64 bit home premium driver and the 64 bit professional driver. I chose the 64 bit drivers because my machine is running 64 bit windows 8.1.

 

Both of those drivers gave me the same message.
"The audio drivers do not support your computer hardware"


Which leaves me back at square one. The only driver I have listed under sound is Digital Audio (HDMI), which I think is my video card, because I don't have any other HDMI ports on my machine other than from my video card. My monitor isn't HDMI however, it's digital, so I'm plugged into the monitor through the digital connection.

Is this the right place to ask for assistance to fix this?
Thanks,

Baggi

I forgot to mention, the machine I'm running on is a Hewlett-Packard HP Compaq dc7800 Small Form Factor.

 

I don't have any of the drivers for the computer and it appears there aren't any windows 8.1 drivers.

 

Thanks in advance,

Hi

 

Please try this way:

 

1. Download Windows 7 64 bit driver - sp45615.exe ( which you already did ).

 

    http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3459245&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D%257CswItem%253Dvc_75954_1%257CswEnvOID%253D4059%257CitemLocale%253D%257CswLang%253D%257Cmode%253D%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken

 

2. Download and install 7-zip from http://downloads.sourceforge.net/sevenzip/7z920-x64.msi

 

3. Right click on the driver installer sp45615.exe and choose 7-zip --> Extract option and unzip the driver.

 

    Like this:

4. Open Device Manager and right click on the High Definition Audio and choose Update Driver. Select Browse my Computer for Driver Software and select the extracted driver folder. Hopefully Windows will install the driver.

Thanks Anshad! I'm headed out for the weekend but when I get back I'll give it a try and let you know how it works out.
