realtek and dolby out of sync

All I can think of is to find the Dolby drivers (or maybe the Audio
drivers?) in the Device Manager and on the Drivers tab, choose either
Roll Back Driver or the Update Driver.

In my Device Manager, under Sound, video and game controllers, I see
four entries that say NVIDIA High Definition Audio and one that says
Realtek High Definition Audio. That doesn't simplify the issue...

Here's some more information which doesn't help me at all. The NVIDIA
ones are for four internal HD audio buses numbered 0-3 on the video
card. The Realtek one is similar, for the onboard sound, It has just the
one bus numbered 0.

As I get ready to send this, I have to add: let's hope someone else
actually *understands* the situation & replies to you :-)

My device manager has just one line item: Realtek driver. I rolled it
back and got a M$ driver, which didn't solve the problem. I rolled it
forward again.

In Program Files / Dolby there're umpteen language files and a few .exe
files, but no setup.

Me, too. Incidentally, I have nothing like a Dolby Theatre setup, so I
can just x the thing out in Autoruns and forget about it. But it
niggles me that installing the latest Realtek driver has apparently left
the Dolby drivers behind the times without any apparent way to update
them. The Dolby application simply won't start: nor will its control
panel.

The reason the drivers work that way, is some of the Dolby technology is
licensed, and paid for on a per-chip basis (royalty). Some of the packages
RealTek offers (base HDaudio chip plus custom software package), they charge
the motherboard manufacturer more for that, than for a generic chip-only
solution.

There's got to be some way they track such things. The last thing they want,
is the Dolby lawyers coming after them, because they "gave out too many
copies of the software". So some feature there, must "police" whether the
Dolby is to work or not. If you go back to the original driver, I presume
it'll work again.

If it was tracked by Plug and Play information, like Subsystem numbers specific
to the Dolby product SKUs, then downloading a fresh driver from RealTek
would have worked. If they're not tracking it that way, and the original
driver was simply a custom version, then only the motherboard manufacturer
will have rights to newer custom versions to replace that with.

Just a guess,
Paul

Realtek drivers can be a problem. Since you have NVidia HD audio as
well, and, I suspect, the drivers are also loaded, what about using the
NVidia audio. I realize that the NVidia outputs are not high level, as
the MBD Realtek outputs might be. I have an older MBD that uses an
oddball realtek chip and driver, and the only way to update it involves
some gyrations to force the new versions to install. It turns out that
the newer version drivers work, but do not recognize the oddball realtek
chip designation. It's a minor variant of a very common Realtek chip.

Hopefully a good one. I'll try the original later. But it's a weird
problem. The message I get is that "the Dolby audio driver is
7.2.8000.13 while the software expects 7.2.7000.4".

I downloaded 7.2.7000.4 last night, and when I click on Dolby in add/del
programs, that's the one that's installed. That driver is the only line
item under Dolby in add/del programs, so I have no idea what software
they're talking about or where 7.2.8000.13 is to be found. It's not in
device manager.

... <later>

OK, so I reinstalled the motherboard version and Dolby works again. I
watched the uninstall, and there were some .msi's for Dolby, so it's
part of the Realtek update: except that the latest Realtek update
downloads something that's incompatible with what I've already got.

This is all very fragile; quite unlike what one expects from W7
Ultimate. I either have to throw away all new Realtek updates found by
Hardware Helper, or Autorun out Dolby. I never intend to watch TV or
play Hi Fi on my PC, so the latter is what I'll do: in fact, uninstall
Dolby altogether.
