Hi, I have just recently upgraded my system to a new Mac Pro (MacPro3,1 - the coffee can style). I have a set of speakers hooked up to the line out on the Mac Pro, and sound works fine in OS X. I am using VMware Fusion 6.0.2. However, I am having a peculiar sound issue in all my Windows VMs. When I power them on, I get a notice stating: Cannot connect the virtual device sound because no corresponding device is available on the host. Do you want to try to connect this virtual device every time you power on the virtual machine? No Yes If I click no, I get asked the question again and again in an endless loop. If I click yes, Windows starts, and the sound works, except it comes out of the internal speaker on the Mac Pro rather than the speakers on the line out. I have multiple Windows VMs, (XP and 7), and this problem affects all of them. VMWare tools is up to date in all the VMs. I have powered down my VM removed the sound card in Fusion preference and re-added it and that didn't fix the problem. I tried removing the sound card altogether but that just gave me no sound at all. I've tried making various changes inside Win7 (the VM I use the most) System Prefs > Sound and that doesn't help either. I'm out of ideas at this point. Any help or suggestions would be much appreciated!!
