realtek and dolby out of sync
I installed latest Realtek driver and now Dolby Home Theatre tells me
drivers do not match. Can't find any downloads on Dolby site, not any mention of Dolby on motherboard driver disk. Any ideas? -- Robin Bignall Herts, England |

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 :-) -- Gene E. Bloch (Stumbling Bloch) |

The Dolby application simply won't start: nor will its control panel. -- Robin Bignall Herts, England |

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 |

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, 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. -- Robin Bignall Herts, England |

I watched the install of the latest Realtek driver; it works fine but no Dolby, and the modules all had Vista on them, so I wonder if Hardware Helper has found the wrong driver for W7? -- Robin Bignall Herts, England |

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. |

Robin Bignall Herts, England 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. -- Robin Bignall Herts, England |
