Thanks for your feedback, it helps us improve the site. 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. The listed hardware IDs are the same as you posted. To make the audio device work, you need to install a driver for it. OEM manufacturers like HP or Dell still sell PC without clearly indicating if they support VTX, even if they indicate “Windows 7 ready” and “64bit version suppported” Could that be caused by lack of hardware virtualization? 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. Then look for the “hardware device IDs” or the “compatible device ID’s:

Are the emulated device registers returning the correct flags? 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.
Bug looks like a duplicate of this one. It is a software utility windowa will find the right driver for you – automatically. Are there other conditions in order to support DirectSound record sources? Make sure you follow the instructions on ticket very closely.
This is what Microsoft apparently did in VirtualPC and it works very well. The same defect also occurs on Win32 host running a Win32 guest, as well as on Win64 host running a Win32 guest. Forget the erroneous “6” that I added inadvertantly after “ICH”. Note that although the discussion isn’t useless it really doesn’t belong here.
The drivers need a reboot to work properly. Hi I’ve recently installed Windows 8 on an XP computer. This one that I tested it on today is a Pavilion Us. Here is the VBOX.
They add hundreds of new drivers to our site every day. Adding an option for an AC97 controller that Windows 7 bit actually has a driver for that actually works might be a better short-term solution.
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 hypervisor, for its virtual audio device driver.
But I REALLY cannot understand why you chose to emulate a completely unsupported hardware with known problems even if you had full documentations about it: DriverGuide maintains an extensive archive of Windows drivers available for free download. How VMware Workstation solved this problem?

And keep in mind that we chose the ICH controller 4 to 5 years ago. The install says it is driver version a3. 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 acc97 it can control and their capabilities.
Andre Da Costa Replied on December 22, Next, go to the sound manufacturer website for drivers. This can only be explained by wkndows in the emulation ic of the host, not on the guests as they are strictly identical. I’m impressed by your rock solid conclusion about our poor design decisions after googling around a bit. You can close the issue for me: I’ve asked this before and will delete unrelated comments in the future.
I’ve recently installed Windows 8 on an XP computer. After all the drivers are fixed or installed, reboot the computer for all changes to take effect.
This board uses the nVidia C51G chipset.

Windows 10, Windows 8. 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 recommend to ask Realtek to add wibdows drivers to VBox Guest Additions until we have better solution. You may use these HTML tags and attributes:
