HDA either wasn’t there back then or rather unsupported. After you have found the right driver for your device and operating system, follow these simple instructions to install it. Really the bug or limitation is not limited to Win64, and I really think it is on the host, not on the guest even if there’s no more supported device for it, all alternate drivers FOR WIN32 do not work: I don’t think there’s any problems with the device emulating what it claims to be. In reply to Andre Da Costa’s post on December 22, Could that be caused by lack of hardware virtualization? Ticket closed defect:

I don’t think this is specific to the guest even if sound works on the same machine using the same version of VBOX installed on the same host OS, to run a bit or bit Linux guest: May be it works because your actual audio on the host is effectively compatible with AC’97 and your audio device is still more basic.

The same defect also occurs on Win32 host running a Win32 guest, as well as on Win64 host running a Win32 guest. The sound also works in a bit installation of Linux in the VM image which works without change, from within VirtualBox or within VirtualPC and on the same hardware machine. If, this can explain why Windows Update can find a driver for you, and not for me.

Follow the easy instruction, and let this program install to the chosen directory given for a sucsessfull install.

Vista bit comes with AC97 driver pre-installed. Other bugs were that the last few bytes of audio data were not played under some conditions causing audible “clicks” in the best cases ; but in some cases, some extra bytes after the end of buffers were accessed as well possibly causing bus errors due to unmapped memory addresses or IO ports, or causing the audio hardware to try accessing to other unrelated mapped addresses in use by another device, and causing for example display corruption, or failure of other critical hardware.


After you have found the right driver for your device and operating system, follow these simple instructions to install it. The SB16 emulation likely doesn’t work for the same reason, nobody ever wrote a bit driver for it because nobody would or could use an SB16 in a bit machine. Bug is related to this one. And you can still install a secondary hardware audio board in any PC, if you wish, without having to disable the primary audio device for Windows it does not matter if they use different working modes, it can perfectly handle several audio devicesjust like you can also install a secondary display device, or a secondary keyboard, or a secondary disk controler, or a secondary USB host controler many PCs today include several USB host controlers, or use a controler working in “dual” mode with one virtually connected to the other.

Are the emulated device registers returning the correct flags? Reconnect the device and power it on. It is a software utility that will find the right driver for you – automatically.

It sounds like the VirtualBox guys should do one of:. Many fast devices are produced today, and then tweaked after production by running series of tests to disable some parts of the device.


In that case you’ll still need to support it for some time at least for the next 3 yearsbecause lots of customers will ONLY be able to support paravirtualization In VirtualPC for Vista, this is what Microsoft chose, using a simple entry to the windowss, for its virtual audio device driver. I tried with and without the guest additions and I windpws tried SoundBlaster 16 with and without the guest additions. I’m sure it’s quite a popular sound card so I’m sure there must be others with this problem though.

In reply to Mike Hall HDA is a matter between the driver and the hardware”. Given that the Realtek drivers seem icn work poorly or not windowd all for many users I don’t think it makes any sense for VBox guys to add them to guest additions when people that really want to try them can install them themselves. 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 wlndows around some common defects.

Make sure you follow the instructions on ticket very closely. But someone needs to explain then why my “virtualized” hardware PnP device Ids are different. I think you’re misunderstanding how the driver interface works – AC97 vs. I did not say that this was the same driver to use in Windows.

Added myself as CC on this issue. However there is nothing coming out of the speakers.
