Intel aa ac’97 audio Driver Sounds like maybe there is a problem with bios settings. Login to post Please use English characters only. If, this can explain why Windows Update can find a driver for you, and not for me. Intel is not obligated under any other agreements unless they are in writing and signed by an authorized representative of Intel. BB code is On. Strange enough, my PC supports both AC97 and HDA it also supports some old games that just support the SB16 working mode , do you mean that it actually has two parallel devices?

Are their reported values updated timely and in order notably status registers, controloer pending IRQs once they have been handled in the guest OS, in order to allow freeing buffers in the audio queue?

Thanks for all the help – but still having problems! One last thing to check is trying different PCI slots for any add-in cards just in case a shared resource is behind the problem.

It is on an old PC: Please assign your manual to a product: Next time we have to make any design decision, we’ll make sure to ask you for advise first. Add Your Answer Tips for a great answer: I had already tried this driver. I’m impressed by your rock solid conclusion about our poor design decisions after googling around a bit. These are just a few examples, but they don’t always report this in the marketed product type, when they judge that the disabled feature is not essential for their market, or when they can provide workarounds around some common defects.

Intel may terminate this Agreement at any time if you violate its terms. It sounds like the VirtualBox guys should do one of:. Please submit your comments, questions, or suggestions here.

Only the bit seems to be a problem. And they’ell be also able to uninstall the “physical” devices from their guest OS by turning off the emulation when unchecking the associated emulations offered by VBOX in its configuration panel.

But more recent “HD Audio” devices are not all directly compatible with this older AC’97 specification which seems to be supported only as a local-only virtualization, indirectly on the guest where it reuses the actual HD Audio driver in a lower layer of the guest OS, and only t oprovide backward compatibility within some applications ; HD Audio devices include additional security requirements which are part of the DirectSound driver model specification for managing, for example, the HDCP protocol over HDMI and digital audio output jacks, and for managing DRM rights and data encryption for the highest quality output including within the audio mixer which cannot mix unsecured and secured audio sources and render a high quality mixed signal to an unsecured analog output.

This discussion will be useful for ICH audio emulation, and their known hardware problems including clock problems, causing audio to be played “too fast” at higher frequency than expected:. By default, all these virtual devices could be enabled and made visible to the guest OS, so the guest OS can use whatever device it supports, and users will hear sound.

I don’t think there’s any problems with the device emulating what it claims to be. And I still don’t have any sound in a Windows 7 guest 32bit or 64bitor Windows XP guest 32bit onlyor Windows Vista guest 32 bit or 64bit ; I only get sound in a Linux guest.

If you have one of the ID’s above, can you point the location where you downloaded the driver? Thanks – it is now finally working. Implementing a virtual HDA controller is likely the way for the VBox guys to go long term it’s supposed on modern Windows and Linux versions without manufacturer-specific drivers but that’s a non-trivial endeavor.


Then look for the “hardware ca97 IDs” or the “compatible device ID’s: Avoid this redirecting link which generates invalid requests and breaks the download, 82810aa that the ZIP file appears corrupted, apparently caused by a broken anti-bot script; I note that the redirector sometimes generates HTTP server errors, or causes the ZIP file to be truncated after just a couple of megabytes.

The same defect also occurs on Win32 host running a 82801a guest, as well as on Win64 host running a Win32 guest. Does not work at all it just worked once, when playing the first sound, then never again, without even changing any setting.

The terms of the software license agreement included with any software you download will control your use of the software. Posted by psri on Aug 05, At a minimum such license shall safeguard Intel’s ownership rights to the Software.

Welcome to Cable Forum. Click on the above link and install the driver. Intel no longer provides email, chat or phone support for this product. As far as a device supporting both HDA and AC97, if that’s indeed the case, it’s either two PCI functions logical devices supported by one device, or two separate devices entirely.

Your personal information will be used to respond to this inquiry only. It seems that for Windows, the WDM driver model does not really make a difference between them: All hardware has bugs; the ones you listed don’t seem that extraordinary.
