VirtualBox 2.1, Windows Vista x64 guest has no sound

[DualShock]

Hi,

I'm testing out the experimental feature in VirtualBox 2.1 where you can run a 64 bit guest on a 32 bit host. I'm running Windows Vista SP1 x64 on an XP Pro SP3 32 bit host, on 64 bit hardware.

I've followed the instructions in the release notes on how to set up the VM properly, and I have turned on the Windows DirectSound option and selected AC'97 audio. Vista can't find any drivers for the audio hardware though, so there's no sound.

Is there another setting that I should be using? Or could this be a bug with 2.1 where the sound hardware is not properly being emulated to the guest?

There were no changes relating to the emulated sound hardware. It seems that Vista guests have problems with sound input but sound output should work. Please could you open a bug report and attach (NOT copy'n'paste!) the VBox.log file to the defect? Thanks.

Done.

Bug 2785 entered.

Thanks!

I am running Apple Mac OSX Snow Leopard and virtual box 3.1.0. I installed Windows 7 x64 and had the same problem. Windows said it could not locate an audio device. I installed the Realtek AC'97 Drivers inside of Windows 7 and the sound now works flawlessly! Great fix!!!!

Thanks for that swampy. The fix worked perfectly for me. Finally I have perfect sound.
