Hello,

im having this certain problem with my HP Pavilion dv6748us Entertainment Notebook PC and i cant find a way to fix the sound. I checked the controlpanel>device manager and could not find the Conexant HD Audio. Then i went to recovery manager to see if i could restore the device,but it wasn't on the list.Then I went to control panel>Programs and features and saw the Conexant HD Audio there, so i right clicked it and it gave me the option Uninstall/Change . I clicked it and accepted to continue,but nothing changed.
so i searched on the HP site to download a Conexant HD Audio device. the installation worked wonderfully,that was until a message popped up and said it could work.
so with all this said, can someone please help me?

thankyou.

Try to download again...from HP site...
ftp://ftp.hp.com/pub/softpaq/sp37501-38000/sp37732.exe (old version)
ftp://ftp.hp.com/pub/softpaq/sp40001-40500/sp40170.exe (new version)

if stil doesnt work...update your directx. Maybe that cause the problem
I have the EXACT same problem; down to the exact same HP model. I tried everything that you mentioned and even tried the downloads that ultraz recommended. I actually thought I had it fixed, until I rebooted & it was the same problem.. PLEASE someone help!
I have a hp dv 9000, but the same problem.
Now I have read lots of replays on this topic, and unfortunately I have the same problem, no fix works, so I am thinking about the overheating problem that my be the culprit in this matter. Did you notice that your hp is overheating on the bottom? Did your laptop shot down itself at least once because of overheating? Mine did, and this is bad news. I even opened my laptop piece by piece, checked all the wires...nothing at first look, then must be a hardware failure, and I think it is because of the constant overheating.
The only thing I didn't try is to reinstall the vista without SP1, somebody said it worked...I don't know.

Still, if anybody has another ideas than everything posted on this thread...I am interested, I still hope, maybe, maybe the chip is not broken....

thanks.
