I bought macx video. Found that I had to install another sound driver. Did so, and the program worked fine. However it broke other functionalities. E.g., no longer could I stream music to my Bose with BlueTooth. Nor can I play an mp3 through iTunes on this MacBook Air.
I uninstalled the program, but the sound driver problem persists. My earlier inquiries to the publisher went unanswered.
Now I have no sound, nor the MacX Video program. Any hope for me?
