I am rather sure I have found a really bad BUG in parallels having to do with the microphone and Windows 7. I have Parallels 6.0 running under Max OS 10.6.7. I have 1 Windows 7 VM and 2 Windows XP VMs. There is a really nice audio editing program for Windows called Audacity which I installed on both the Windows 7 and one of the XP VMs. This program has the ability to monitor and continually display the microphone signal level. I ran this monitoring on the Windows 7 VM and it showed the microphone to be working. BUT after about 1 hour, the microphone STOPPED WORKING! I also ran this monitoring on the Windows XP VM (not at the same time as the other VM) and the microphone was still working after 6 hours. Just to verify, I also ran the Audacity microphone monitoring on a Windows 7 PC (not a mac w/Parallels) and the microphone worked for over 3 hours (after which I had to give that computer back to its owner). I got started on this issue when a VOIP application stopped working when I was in a call this morning, after about an hour, using the Windows 7 VM. As far as I can find, there are no setting in Parallels or Windows 7 that would have any effect as to disable the microphone after an hour, thus this clearly looks like a BUG in Parallels. I do not have a service contract, nor will I get one. Parallel's support mechanisms seem to all require one, in order to contact anyone at the company. Without a service contract, how can I report this BUG to Parallels?
