We do the bookkeeping to mark the buffer as empty, and the DMA engine then continues with the next available buffer in line till it reach the Last Valid Buffer. Sound is working fine on the same host with an XP guest. Note that your submission may not appear immediately on our site. HDA is a matter between the driver and the hardware, Windows doesn’t care which interface it uses aside from what audio features the device claims to support. Intel also makes motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphics chips, embedded processors and other devices related to communications and computing. You should be ashamed.

We learned that hardware can give weird problems at times and being software people, it is hard to cope with it.

lookin4 AC’97 Audio Controller for Intel 82801DB(M) ICH4

Intel is one of the world’s largest and highest valued semiconductor chip makers, based on revenue. Pros Restored my sound to orig specs on the first try.

Since there are 32 buffers, audio is always catching up. Intel also makes motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphics chips, embedded processors and other devices related to communications and computing.

Only the bit seems to be a problem. Or say which is the manufacturer and version, as reported in your installed device? Not sure if this integratwd the right driver for your Intel Desktop Board? If, this can explain why Windows Update can find a driver for you, and not for me.

Certainly no, I won’t buy it and anyway none of my PCs have the support for hardware virtualization, even the msot recent one that I bought 1 month ago, due to ambiguous Intel specifications of its processor which has two distinct models with the same commercial name 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.


This can only be explained by a bug in the device emulation on the host.

I recommend to ask Realtek to add those drivers to VBox Guest Additions until we have better solution. You are logged in as.

Qaudio – for actually playing out audio files Qvolume – for controlling volume of the device and Qstat – for maintaining statistics like number of bytes buffered, time spent etc. The maximum size that a buffer in the BDL can have is K.

I don’t think there’s any problems with the device emulating what it claims to be. During this period Intel became the dominant supplier of microprocessors for PCs, and was known for aggressive and anti-competitive tactics in defense of its market position, particularly against Advanced Micro Devices AMDas well as intgrated struggle with Microsoft for control over the direction of the PC industry.

It sounds like the VirtualBox guys should do one of: Only download this driver. We don’t wait for partially filled buffers to fill till completion before playing them ckntroller since that would cnotroller latency.

The listed hardware IDs are the same as you posted. You may not remove any copyright notices from the Software. Design Decisions 32 physical buffers We have allocated 32 physical buffers that so we could use all the buffers in the BDL. Results 1—10 of 1 2 Since data has to be memmoved into those buffers, it is an expensive operation. Pros driver is working. Vista bit comes ibtegrated AC97 driver pre-installed. You may af97 sublicense or permit simultaneous use of the Software by more than one user.


We did a similar thing for VBox 1. After closing all my windows I had noticed I had downloaded two other game software programs and some other thing I didn’t know what it was.

Of course I go to my control panel and try controler remove these unwanted downloads two are removed but one of the game programs is now stuck on my computer. If you have one of the ID’s above, can you point the location where you downloaded the driver?

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 ixh4 devices that it can control and their capabilities. Does it ckntroller the record capabilities when just the play capabilities are needed?

As I mentioned, no actual bit-capable machine would have had this hardware.
