ok i have sound when you first log onto windows 7 and i have sound when you log out of windows 7 but i have no sound anywhere else.I checked the settings in sound on the control panel but it says everything is working fine, I have the vm additions installed because i can move the mouse in and out of vpc. Any suggestions why i cannot play music or even in ie 8 here the music when a video plays?thanksrobin

Hi Robin,so you have a sound from the VM when you start up and shutdown the VM, but you have no sound when you go into the Control Panel --> Sounds --> Change system sounds --> choose Windows logon or logoff?Peter Forster, MVP Virtual Machine, Austria

Yesterday Windows update asked for an update for the mp3 update. After rebooting Windows 7 I still had no sound.Today when i went onto the vm and clicked on Windows 7 and it went into the logon screen I heard the sound again. Logging in- soundNow i go to try to play music and I now have soundI go to pandora.com- soundbutthe sound is real choppy and cracklyNo idea why it now worksbut again it sounds terrible.robin

Is this a function of the vm? because it is enabled with hardware acceleration and when going into the host it shows i cannot change the hardware acceleration at all on this computer.robin

I also installed Win7 on VPC 2007 SP1 to try some different configs, and interestingly, I wasn't even able to load drivers for the sound card - I simply get "Unknown Multimedia Device" in Device Manager. What drivers are you using? FYI, I installed it using the Vista option, so it's using the Vista sound engine, not the generic SB16 device that is emulated for other OSes. Thanks.

Thanks.I installed it using the the vista OS too. Did you install the vm additions? that helps get sound at least. Why it is choppy is beyond me.robin

Also since Microsoft knew Windows 7 was coming out in beta and had to know that so many would use it in VP- whynot set up the vm additions for Windows 7. This way we could fully test the OS without all these complications.robin

I did have the additions installed, but still no dice. I ended up reinstalling VPC on the host machine, and reinstalling the additions to Win7. That finally got the sound going.As far as choppiness is concerned, I haven't experienced that, but I haven't had a chance to do a lot of testing in that aspect yet. But some things come to mind. Check your performance preferences in VPC to ensure that the guest OS is running at full speed all the time. Otherwise, priority will be given to the host OS, even when you're working in the guest OS. Also, you didn't mention your memory allocation, but the more, the better. Assuming you're multitasking, 1 GB really isn't enough to do anything worthwhile like listen to music. robinb9 said: Also since Microsoft knew Windows 7 was coming out in beta and had to know that so many would use it in VP- whynot set up the vm additions for Windows 7.
