Hi all!
Just wanted to say that the beep is gone when you use the second slot!
Just in case someone else gets this weird problem it might
be good to know.
Well there´s some good news, i got a reply from a sound technitan (is that how it´s spelled?) and he had the exact same problem with one of three cards. He reformated the card and it worked. I will try that in the morning but the real bummer is that i have recorded files with an actor that can´t be reshot...
