For me, it's a matter of the "trust chain".

I trust a RealTek driver I get directly from the RealTek site.

I don't trust a driver that comes from the Driver Helper server.

While good AV software can catch things known to exist, nothing
would stop the owner of the Driver Helper site from inserting
their own custom malware.

So it's a matter of trust. Or expense, for the ones that
charge money for the privilege of (trying to) identify
your drivers for you.

In one of those driver programs, the menu offered after the
scan, had roughly twice as many drivers listed, as were actually
needed. So some of the programs "plump up the menu", to make
like they're doing you a big favor.

*******

On my WinXP machine, I don't even take the drivers off the Windows Update
menu, because 9 times out of 10, the version doesn't exist in the wild,
and there's something wrong with it. It's possible the ones offered
in Windows 7, aren't quite as obscure in terms of versioning.

I got a driver once from Microsoft (default ATI driver for my video
card, on the installer CD), that only operated one of the two display
channels on the card. If you played a 3D game, and alt-tabbed out,
all acceleration in the desktop was disabled. That's the kind of
thing Microsoft distributes. Well... tested... stuff...

I bought the commercial version. It downloads the drivers, they're
subjected to the usual virus check for anything downloaded, and you
CHOOSE whether to install them. Each driver has full details of where
it came from, version, date etc. and you can check back to the source to
verify veracity.


So when you look at the file name, do you see something similar offered
in the HDaudio section of the RealTek site ?

Motherboard audio solutions (at least for recent systems), are
either AC'97 (five years ago) or HDAudio (modern). The RealTek HDAudio
driver should be a "jumbo" driver, which handles most all of their
HDAudio sound chips.

Some chips in the past were PCI, and an enthusiast sound solution from
years ago, might have included a PCI chip soldered to the motherboard.
But for most of the rest, they're the simpler AC'97 or HDAudio, where there's
no intelligence to speak of, and the chip functions as an "audio pipe".
You send samples to the chip, and it has ADC and DACs for making analog
voltages to/from the samples.

The audio driver package, will usually have a huge .inf file. And that
file includes mappings from chip facilities, to the port wiring on
the motherboard. If a chip supports "three jack" and "six jack"
installations, the .inf file helps sort out and get the jack
assignments right.

You and Char have now given reasons, and thank you both for that, but
what my post meant by "they" was the posters on the forum that Char
pointed to.

The posts there essentially just said "Don't use it" without hinting at
any reasons.

The version names do not match. That's why I had trouble with
downloading anything from Realtek, but... see below...

either AC'97 (five years ago) or HDAudio (modern). The RealTek HDAudio
driver should be a "jumbo" driver, which handles most all of their

I picked out the latest Win 7,8, Vista driver from Realtek (50 GB) and
installed it. It works but there's still the mismatch with Dolby.
Exactly the same message.

50GB? :-) Probably 50 MB.

Incidentally, the latest Realtek driver according to Hardware Helper is
6.0.1.6649. The one I just downloaded from Realtek is 6.0.1.6662. Both
of these are about 50 mB.
The one on the Realtek site is 6.0.1.6554, and is over 100 mB, the
difference, presumably, being Dolby.

You still haven't ditched that silly Hardware Helper? What's taking so
long?

BTW, mB = millibytes, a unit of measurement not in common usage. You
probably mean MB (megabytes).

I guess I'm not being very helpful.

Can the files be opened with 7-ZIP ?

http://en.wikipedia.org/wiki/7-zip

That's how I take various drivers apart, compare them, and so on.

Not all drivers can be disassembled easily. Some are Installshield,
with encrypted CABs inside. Others, they use a "packer", like UPX,
at the top level, and then 7-ZIP won't open them at all.

So actually being able to guarantee disassembly is pretty difficult.
Too many techniques to obscure them.

On occasion, I use WINE in a Linux virtual machine, to crack
open an installer. With less danger to my running Windows OS.
So that's another forensic technique that works sometimes.
I use that for webcam drivers from Chinese sites, the ones
where you wonder whether they're infected or not.

For dodgy sites, you can also upload the file to virustotal.com
and scan it there. I believe I had one Chinese webcam driver,
that "smelled bad".

I'd like to help you, but I really don't understand how the
software knows Dolby stuff is to be installed or not. I can't really
simulate that here.

I use Uniextract to unpack installers and other packed files:

And for Inno packed installers I use this Inno Setup Unpacker method:

Not particularly, and HH has served me well enough for a couple of
years. This Dolby business and the licensing is a weird case.

http://en.wikipedia.org/wiki/7-zip

I noticed that the Gigabyte one used 7-Zip to unscramble itself. I
didn't see any unscrambling for the others. They all used InstallShield
in a two-step process:
uninstall the old
reboot
install the new

That's how I take various drivers apart, compare them, and so on.

The latest Gigabyte driver is working fine, except that Dolby doesn't
load automatically on booting. The rest of the technicalities are well
above my pay grade, but thanks for some great insight.

Hi, I don't know if it would solve the "out of sync" problem bescribed
in this topic, but I didn't see if anybody write about that the Dolby Home
Theatre works just fine with newer Realtek drivers actually. I think that only
interface is not working and gives that error about 7.2.7000 vs 7.2.8000.

Try this:
Go to Playback devices in Windows 7 Start-Control Panel - Sound
Click RMB on Speakers or Digital Output (whatever you have) and than Properties
At the top you should have Dolby tab where Dolby Home Theatre v4 interface is.

Thanks for getting back to me on this. Following the instructions I get
"Current Dolby driver is 7.2.8000.13. Software application expects
7.2.7000.4"
Downloads of Realtek drivers from Realtek do not contain Dolby drivers,
AFAIK. I have a Gigabyte board, and downloading the Gigabyte sound
driver is supposed to consist of two drivers, Realtek and Dolby, that
install one after the other. The latest one I downloaded didn't. I
have all of the past Realtek drivers on disk and I suppose I could go
back through them until I found a match, but it's too much trouble. I
only have two desktop speakers.
