Problems with EliteBook 840 G3

[Chris-G]

Same here, 840G3, Win7 x64, driver pack 73204 UAC prompt for HD Audio driver at first login. Has anyone happened on a solution?

We had the same issue (Conexant Audio UAC prompt) on this years new models (840 G3 and 800 G2 AiO)

Solution/workaround: Remove the Conexant Audio driver from the driver set. During Windows installation and device detection, the unit will automatically download MS HD audio driver, and this works perfectly fine, both microphone and speakers. for us it worked for both HP 840 G3 and 800 G2 AiO

I tried to research why this gave the UAC prompt: To me it seems like since the driver is signed, during OS installation the driver is added to the driver space, but not installed as the driver is signed by Symantec not by MS, and Symantec is not a trusted CA (atleast not in our environment)

I'm coming across the UAC prompt as well.  If Google search a bit for "Conexant UAC" you'll see threads discussing this issue beyond just this model or even just Conexant's driver.

Just wanted to confirm the issue with the Audio Driver also applies to other models, im seeing this on:

• HP Elitebook 840 G3
• HP Elitebook 820 G3
• HP ZBook 15 G3
• HP ZBook 17 G3

I was able to temporarily workaround the issue by setting ConfigFlags to 0 for the driver in registry, but it seems the change was later undone by unknown causes.

Has anyone found a working solution yet? Or is the only working solution to have someone log onto the machine and finish the install?

HP still has not provided a solution for this as far as i know.

What I've ended up doing is just delivering the Conexant Audio driver installer as a package.  Since the most recent Bluetooth drivers required the same treatment it wasn't that big of a hurdle.

Which install command did you end up using for the bluetooth drivers and on which OS?

[TribleTrouble]

We still got the issue, even when we distributed it as a package in our environment bdam.

HP technical support said this to me 3 minutes ago:

The audio driver problem with SCCM is a skylake bug that is being worked on.

Update your bios

And if that does not work, disable intel smartsound in the bios.

For the Bluetooth drivers I just used the MSI installer with the usual non-interactive flags: msiexec.exe /i "Intel Bluetooth.msi" /qn

For Conexant there's a silent installer batch file though I run a slightly modified command so that the log file doesn't go to the root of the C: drive: Setup.exe -s -l:%TEMP%\CNXTHDASup.log

In our case, these both are targeted software packages so they get installed after the OS has been loaded by the management agent.  We are in the middle of a migration to SCCM so if these were part of a Task Sequence directly I'm not sure what would happen.

Mea culpa: TribleTrouble was correct and even when delivered as a package we're getting the UAC prompt.  I think in our earlier testing someone was logging in to watch the intall succeed/fail and that was enough to avoid the prompt.

[TribleTrouble]

Did anyone try disabling smartsound yet?
