A few years ago I started using Windows 7 on my Mac with software called Parallels. This allowed my to run Internet Explorer and Quicken in Windows, on my MacBook Pro laptop, something very convenient because I didn't want two separate computers in my office - one for Windows and one for Mac.
All went well until last week, when all of a sudden I was getting no audio on the Windows side, only the Mac side. Since I had just upgraded to Parallels Desktop for Mac version 9, I was entitled to 30 days of support. My first support phone call lasted 90 minutes and they couldn't fix the audio issue. This morning I received a follow-up email from the folks at Parallels and they said that I should just upgrade to the latest version of Desktop 9 for Mac. Thankfully, this latest version 9.0.24172 fixed the audio bug and I can now listen to audio again.
The hallmark of a successful company is to keep the customer happy and fix whatever is broken. Parallels did that for me.
An alternative to using Parallels is virtualization software called vmware. I chose Parallels over vmware because it looked easier to use and install.
