hi all, I have an issue from time to time ever sense updating to the latest update of mac os where when I'm doing some task such as reading a webpage or navigating my mac i sometimes have the issue where voiceover stops speaking, and all i get are the movement sounds and no speech, and then it comes back after about a coupel of minutes or so. I don't even have a headset on when this happens, it's happening with my inturnal speakers. does anyone else have this issue?
