I'm using Pinnacle 11 Ultimate and everything was ok until I was recording a voiceover (not the first one by a long way) and now I get no sound through Pinnacle although all the Pinnacle buttons seem to be set correctly i.e. are not muted. I can play MP3's and Videos through Media Player and the sound is fine but can't get any sound via Pinnacle. I have de-installed and re-installed Studio but to no avail - HELP!!
