Opened 9 years ago. To make the audio device work, you need to install a driver for it. This thread is locked. HDA either wasn’t there back then or rather unsupported. Win 95 File Size:

Ticket closed defect: The only thing xc97 do is then to upgrade the emulation to a more recent version. Vista bit comes with AC97 driver pre-installed. And I still don’t have any sound in a Windows 7 guest 32bit or 64bitor Windows XP wiindows 32bit onlyor Windows Vista guest 32 bit or 64bit ; I only get sound in a Linux guest. Windows 10, Windows 8. Hi I’ve recently installed Windows 8 on an XP computer.

Realtek AC97 Audio Driver for Windows 10, 8.1, 8, 7, XP, Vista

Added myself as CC on this issue. Windows 7 bit seems to be able to download a winows from Windows Update that works fine only tested the RC version.

I used this drive on an eMachines W PC and it worked fine. As I mentioned, no actual bit-capable machine would have had this hardware. The host audio is HDA on this system.

Open the Windows device Manager, click in the Multimedia devices category, select the device, and open its properties. That means it really isn’t wise to choose to emulate only modern hardware.

It almost certainly doesn’t support both. The Realtek AC97 drivers do install though they complain about being unsigned but on my system Fedora 11 bit host the audio output is crackling and distorted. This is just the first step, not the final solution.

All you have to do is sit back and wait for it to finish. I’ve asked this before and will delete unrelated comments in the future. And keep in mind that we chose the ICH controller 4 to 5 years ago. None of the solutions found do really apply to VirtualBox emulations, because all these solutions using various OEM drivers with various workarounds for the same problems are only meant to solve variably the same issues in a real hardware but not in the virtual emulation where they are not at all relevant and where they would finally cause more problems.


It may explain why this audio device is no longer supported by Intel, Microsoft, or the OEM manufacturers that included it. The install says it is driver version a3.

The Winsows drivers would be a reasonable solution, if they worked properly – there seem to be issues with audio crackling and volume control.

Reboot the Computer After all the drivers are fixed or installed, reboot the computer for all changes to take effect. All hardware has bugs; the ones you listed don’t seem that extraordinary. Many flat screens are sold with a few “acceptable” dead pixels for the same reason, otherwise the production would not suffice to the demand, and the devices would be much more ad97 Intel, AMD, and nVidia are doing the same with their CPU and GPU processors and chipsets, by recycling and downgrading them when they can’t fully reach the expected zero-default level for which they were initially built: The driver installed fine, and it appears in Windows 7, and media player in guest “sees” an audio device, but host doesn’t produce any sound.

We will probably add a virtual HDA device next year. This has just worked once, then failed again after restarting Windows no more sound. Are the emulated device registers returning the correct flags? 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.


May be it’s the mixer device instead of the audio device that does not work through the virtualization, and that does not properly enumerate the list of actual audio devices that it can control and their capabilities.

I hope they can be slimmed down significantly. Even CPU processors have bugs, the situation is even worse with today’s GPUs which are even more complex and where none of them are fully working fully as described in specs, or even wokeing the same way in the same production series, with some parts generating errors that need local corrections, or with parts failing quite rapidly because of heat or because of random defects in the chemical production process; chipsets are also very complex units as they work with so many different clock constraints, that need special autodetection algorithms to provide alternate working paths either in the software driver or in the mutable firmware embedded in the firmware.

It enables you to one-click identify all the driver issues, repair drivers by downloading and installing the best-matched drivers, update to the latest driver, backup drivers for safe rescue, restore drivers from backup, remove drivers, download drivers for another computer, and do more.

I have the same question
