Please attach a VBox. Are you supporting power management states described in the ICH specifications for powering on the device only when it starts being used , or do you assume that these virtual devices will be always on and that the guest’s driver will not verify it? 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. Pros Restored my sound to orig specs on the first try. I’ve asked this before and will delete unrelated comments in the future. No thanks, continue to download AC’97 Audio Codec.

The problem is purely that there is no driver that works properly with this device for bit Windows, so it’s entirely a guest issue. Download the driver elsewhere. Anyway, I’ve converted all my PCs now to Windows 7 host. Do you recommend it? Implementing a virtual HDA controller is likely the way for direectsound 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. Laws concerning the use of this software vary from country to country.
Are the emulated device registers returning the correct flags? This can only be explained by differences in the emulation layer difectsound the host, not on the guests as they are strictly identical.

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. Likely that codec doesn’t completely match the one VirtualBox is emulating.
And yes, sandervl73, I understand that your reply was a joke a form of disguised critic. Integrated Audio Causing Windows 7 to Freeze!
Unable to work in windows 7. A lot of cons More. 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. Opened 9 years ago. This has just worked once, then failed again after restarting Windows no more sound.
Tried it twice like an idiot and had to go through checkdisk in full. 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. Clearly, the choice of the old ICH for the virtualized emulation was a really poor choice of VirtualBox designers, and it would have been much better to emulate a supported device without such known hardware bugs: Of course I go to my control panel and try to remove these unwanted downloads two are removed but one of the game programs is now stuck on my computer.
Are their reported values updated timely and in order notably status registers, and pending IRQs once they have been handled in the guest OS, in order to allow freeing buffers in the audio queue? Windows warned me against it but I went ahead anyway and the computer crashed.
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.
Soundmax Integrated Digital Audio Have tried numerous drivers.
Now I will have to spend the rest of the day fixing this instead of working. The Realtek drivers would be a reasonable solution, if they worked properly – there seem to be issues with audio crackling and volume control.
When a register is used to index and remap other registers in the allocated IO space for example to map audio data buffers in the small IO space before writing to themis this setting remembered? Overview User Reviews Specs.
However there is nothing coming out of the speakers. Do you support all the needed register access orders used by drivers?
