I recently installed Windows 7 into a VM under Parallels in order to get better performance on playing lotro (Lord of the Rings Online) vs. my existing Vista VM under Parallels. FYI, the Vista VM is a bootcamp partition, while the Windows 7 is not. (I would actually like to resize my partitions in order to be able to create a new Windows 7 partition, but that is another issue.) The problem that I am having with Windows 7 and lotro is that the game sound quits after a while. Even after the game stops producing sounds Windows 7 still is able to produce sounds. I have asked in-game and no one running on a Mac with Windows 7 seems to have this issue. However, I haven't found anyone running it under Parallels to see if they suffer the same fate. All the software is up to date. I have tried reinstalling Parallels tools and the sounds driver. I don't have any sound issues either running the game under Vista through boot camp or as a VM under Parallels. Any ideas on how to rectify the issue?
