No Sound on Z800 and Windows 10

[agdodge4x4]

Device security has no mention of anything related to audio.  Not sure why.  There is not a jumper on the board right?  Looks like you can't disable onboard audio anyway.

FYI,..........hp specs this system with a optional  Creative Sound Blaster X-fi Titanium Audio Card (Sb0880) which i own and have used in the z800 along with other computers, it's a nice card the HP OEM model also supports auto switching into/out of EAX modes all i had to do was insert the card and it became the primary sound device, the bios detected the new sound card and auto configured it corectly if i wanted to i could also use device manager to disable onboard sound but this was not really nessary

Do things in this specific order, and I also use this basic method to clear out nVidia Quadro ODE drivers and do clean installs of the latest ones for an install that is old and potentially corrupted:

1.  Go to the Z640 HP drivers download page for W7P64 or W10P64 and download the SP76061 (Realtek driver installer for 6.0.1.7945, released by HP 12/16/16).  Have that on your desktop.     The Realtek driver installers are universal installers that generally will recognize and work on older as well as newer Realtek chipsets.  This method would work for a xw6400, for example, also.  This installer is for W7 through W10, 64-bit.

2.  Disconnect from the internet.... you don't want W10 to hijack this process, so cut off its access to the outside world.

3.  Go into the Control Panel for your W10 install and go to the uninstall programs section.  Go to any nVidia or ATI sound driver related entry you might find there and uninstall that.  Do not restart.  Go to any Realtek entry you see and uninstall that.  Do not restart.

4.  While still in Control Panel go to the Folder Options equivalent and select to show hidden files and folders.

5.  Back out of Control Panel and go to C drive and look on the root level of C for any Realtek entry.... delete that.  Then into the 3 program files folder including the normally hidden one and delete any Realtek entry.  These would be Program Files, Program Files (x86), and Program Data.  If you don't dump the Realtek directories from those 4 total places an old installer may get automatically activated on your first restart and you are stuck again with old/bad drivers.

6.  Restart, and wait a bit.  Som e drivers from the MS Windows hidden repository of drivers may get installed, but these should get over-written in step 7 below.

7.  Run that HP SoftPaq to install the Realtek drivers and program.... there will be a restart needed and it will likely do some added install after that restart.    Give it some time.  Should be good to go then.

8.  Back to Control Panel.... turn off that option to see hidden folders and files.  It is best to not run with that left on, but some of us do.  I don't advise that generally.  Reattach to the internet.  For this type of thing I generally don't see W10 try to force its MS-directed driver over what you did, but that is ensured by having your driver date (from Device Manager properties) be more recent than what MS has in its package.  I get my nVidia Quadro ODE drivers straight from the nVidia site and those thus virtually are always newer than what MS offers.

This did not work for me.  Still Red X.

In fact, nothing in the drivers section of sound in device manager changed.  It looks exactly the same.  The only way I could get anything to change is to manually install that driver via "add legacy hardware".  That driver is now there, but it has a yellow bang on it.  There are still 4 instances of "High Definition Audio Device".  No clue what those are, but uninstalling and deleting them does not get rid of them.

NO idea where my post disappeared to.  I tried the steps all outlined in this thread.  Nothign worked.

I still have no sound.  I have updated, re-updated, and manually installed drivers for realtek.  Nothing is making it work. The Realtek drivers suggested for Z640 installed but gave device code error 10.  No go on that either.

NEVER had this much trouble with a device and Windows since Win 98.  Yikes.  What a pain. 

I currently Have Realtek High Definition Audio Controller with a yellow Bang on it, and device error code 10:  The request is not supported.

I ALSO have FOUR instances of NVIDIA High Definition Audio Audio.  I have NO CLUE what these are or why they are there.  I tried disabling them all.  No help.  I have  hidden devices in the sound list as well which I have removed but they came back:

MS Streaming Clock Proxy

Quality manager proxy

service proxy

tee/sink to sink converter

tee/sink to sink converter

microsoft trusted audio drivers

All of these are listed in addtion to the 4 NVIDIA High DEfinition Audio.

Again, I cannot reinstall windows.  I do not have the access or software for it.

it is remotely possible that the onboard sound codec is defective (unlikely but remotely possible)

i would simply take the path of least effort at this point and install the HP OEM sound card and be done with it

here's one for under 20.00

It makes no sense.

I UNINSTALLED the NVIDIA drivers.  After reboot, the same stupid software is BACK!

What is up with that?  WHy is it defaulting and auto installing?!

Also, why do I need an HP supported card.  Won't any old sound card that fits in the slot work?

[agdodge4x4]

Can I manually go through teh device manager and find the path to each of the files listed and just force delete everything in system32 path?

[agdodge4x4]

No reason to uninstall anything.  Windows should grab what it needs.

When I run 'unknown device identifier" the audio comes up as an NVIDIA GF100 High Definition Audio Controller.

Is this something built into the Quadro 6000 video card?

For me on this Z400 under Device Security the on-board audio chipset can be turned off under "System Audio".  I'll check on a Z600.  I don't have a Z800 but DGroves does and all works well under W10.  It is not the Z800's fault, nor is it yours.

For this situation (backed into a corner, highly frustrated), I've learned over and over..... reinstall.  Your W10 is already activated under the MS W10 activation servers.

I'd take the drive out, reformat it after deleting all partitions, and reload from the W10 MS installer mechanism.

Your experience with auto-reload of nVidia drivers after deleting everything my way means the MS hidden drivers stash for W10 uses a pre-installed set of older nVidia drivers.  When I install nVidia drivers I check the box for clean install and only select the single first driver.... all else is deselected under the custom driver installation option.  This is only for Quadro cards.

The Z800 is fine....... I wish you lived down the street from here.

I have MS Office on here too that was installed, and I don't have the CD for that to re-install, or the key I need.  Its Office 2016.

There is nothing else on here I need.  I don't know what process to go through to re-install windows 10, with it's latest build, knowing I have a windows.old means it was probably somehow upgraded.  I don't have any media to re-install windows 10 that is activated or MS Office that is activated.

I just feel like there is some conflict between the audio drivers installed for the quadro video card and the realtek audio board.
