I'm running AS on my MacBook Pro using Parallels Desktop and Windows 8.1. All my software is up to date. That being said, I've tried to use the internal mic to do simple audio recordings (not for my commercial clients) and it records the audio at such a low level it is difficult to hear. Has anyone else experienced this issue? I've explored Parallels Support to no avail. I'm going to go and purchase a USB microphone, but I thought I'd see if others were having similar issues. Other than this, AS works flawlessly on my Mac using Parallels.
