I run XP through Parallels 24/7 on my iMac, and it works great. However, I work from home a lot, and we use Microsoft Office Live Communicator to chat. The problem is that it won't output my callers' voice to the speakers. The microphone works -- they can hear me -- but I can't hear them. When running through the setup wizard for voice chat, everything is fine except for the speaker test -- I don't hear anything. All other sounds work though, for all apps...including Communicator itself. I hear all the notifications and ringing noises and all that. Just nothing from voice chat. Can anyone help with this? It's pretty important for me. Thanks.
