Rehan,

Re: HP Compaq 6720s "The HDA Audio bus driver required and not found"

i can understand that my book is of a different model, but these ethernet cards inside are almost all the same.. after a two-day reinstalling my sound finally started to work, i don't even know how did i do it, but anyway, the ethernet still does not seem to work.. i even flashed my bios but besides the fact that it was already the same date as the one from HPsite, it did not change anything..

Re: HP Compaq 6720s "The HDA Audio bus driver required and not found"

hello i have the same problem with the ethernet
when i connect the network cable i receive the error "limited or no connectivity"
the driver is from hp.com
i try to reinstall the win xp with sp2 same problem
i attach a print screen from event viewer
this is the error i receive when i connect the network cable
-------------------------------------------
the big question is why no one from hp, posts here to lets us now what is going on
because we bought a hp product, so they have to give us support and proper drivers

Re: HP Compaq 6720s "The HDA Audio bus driver required and not found"

Hello everyone. It seems I find solutions to problem with HDA Audio bus driver, like Viktor Illeš has.

I've got compaq 6720s. First of all I try to install (UAA) Bus Driver for High Definition Audio (sp33867). When its done I reboot my notebook and try to install SoundMax Driver (SP38529), but it said "The HDA Audio bus driver required and not found". There is one undefined PCI device with a yellow mark in Device Manager.
I try to install KB888111 and reinstall audio drivers again, but it does not help.

You must meet this situation, if you read this tread.

So, next I remember, that I don't install modem driver yet. And I can't find any modem device or any other suspicious unknown device in Device Manager.

I install this modem driver (sp36004)
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=32...
but nothing happen :). I still don't have any modem in Device Manager.

But that driver unpack its files in folder C:\SWSetup\SP36004A on my hard drive.

Than in Device manager I choose marked PCI device, right mouse click, update drivers. Don't use Automatic install, choose path to drivers youself. You must enter folder "C:\SWSetup\SP36004A" (or where you extract drivers) like folder to search.

And miracle happen ! :)
My unknown PCI device became "Microsoft UAA bus driver for High Definition Audio".

Now you can install Sound MAX audio driver (SP38529) and Modem Driver (sp36004) as usual. They fits well.

It is because audio device and modem nestet on the same Microsoft UAA bus.

I have got two additional device in Device Manager now:
SoundMAX Integrated Digital HD Audio
Agere Systems HDA Modem.

That's all. Hope it help.

Have a nice day.
