Missing audio support in 64 bits Windows Vista and 7 guests

[DualShock]

Per forum thread at ​http://forums.virtualbox.org/viewtopic.php?t=12316, I am testing out running a Vista x64 SP1 (installed with integrated DVD) guest OS on a Windows XP Pro SP3 32 bit host. I have the proper 64 bit hardware and have configured the guest OS per the user manual for 2.1. I enabled sound using Windows DirectSound and ICH AC'97 options.

Sound is not working in the guest OS. Device Manager in the guest OS shows sound hardware, but no drivers were able to be installed for it (yellow exclamation mark).

UPDATE on 06/26/2009:

Using VB v2.1
SOLVED: For error "No Audio Device Installed". After some time of searching the net, I was finally able to get sound working in my virtual Vista Ultimate x64 install. All that I had to do was install a driver for the VirtualBox virtual soundcard hardware. No reboot was necessary.

1. I went to ​http://www.realtek.com.tw

2. I clicked on "Downloads", then on "AC'97 Audio Codecs". On the downloads page I downloaded the file with the description "Vista/Win7 (32/64 bits) Driver only (ZIP file)".

3. Once downloaded, I extracted the files and pointed the Device Manager driver installer to the "6303_Vista_Win7_PG537\6303_Vista_PG537\Vista64" folder. It found the driver and proceeded with installation. Once it was done the Device Manager refreshed itself and showed the sound card as installed and working.

I loaded up some sounds and everything was working excellent and sounded great too.

Confirm - Solved for Windows 7 64 bit client. Download drivers from ​http://www.realtek.com.tw as described above. Unzip and install in Windows 7 64 bit client. Sound drivers work. Note that realtek.com.tw web site is very slow, download takes over 30 minutes.

This didn't work for me. Are there any hosts where this is known not to work? My host is Fedora x64. I keep getting "Hardware changes might not have been detected". We've got a thread going in the forums: ​http://forums.virtualbox.org/viewtopic.php?f=7&t=26476&p=118682

It is working although the sound is poor. The sound stutters. You can hear the sound and understand it but if you are expecting to listen to music you will be disappointed. This is an improvement over VMWare server where the sound was an cacophony of multiple sounds played at the same time over each other.

When I download the drivers from the RealTek site, they unpack to Vista_Win7_R240/Vista64. Have the drivers changed since mehtuus posted?

Looks like I downloaded the High Definition Audio codecs. Sound seems to work pretty well now. :)

Strangely, the stuttering somehow seems to be related to the number of CPU's allocated to the VM. I've reduced the number of CPU's from two to one. The problem's (almost) gone now...

If you choose to use ALSA instead of PulseAudio on the VM's settings, then it is no stuttering.

[Peter Bennett]

A new Audio Device (Intel HD Audio) has been added in VirtualBox version 4. This should fix the issue. Audio drivers should be available in Windows 7 for this audio device. Just change the VM setup to select Intel HD Audio as the audio controller.
