We've been messing around a bit and finally got it working
Troubleshooting sound issues in VMWare Player
I've been messing around with Windows 7 in a virtual machine for a while now and recently installed a fresh copy, but I ran into a problem. For some reason, there was no sound coming out of my Windows 7 virtual machine. The other one was working fine, so it was really strange. If you're not getting any sound out of your Windows virtual machine in VMWare Fusion, there are a few troubleshooting steps you can try.
I finally got the sound working on my new Windows 7 VM, but it took me a while to figure out what the problem was. In this article I'll walk you through a few possible solutions and hopefully one will work for you. If not, leave a comment and I'll help you out.
The first thing you want to do is make sure that the VM actually has sound enabled. You can do this by going into Virtual Machine and then clicking on Settings.
