Avid Free DV 1.6.1 is a freeware program. I tried the windows version of Avid Free DV 1.6.1 today. After starting the program I got a message box with the following content: Exception: ADM\_WAVE\_MIXER\_OPEN\_ERROR.
On the web I only found the recommendation to use a soundblaster sound-card.
There was also a user with a soundblaster card reporting this problem.
He mentioned that he has a onboard-soundcard, too.
So thought: Maybe Avid’s FreeDV has a problem with systems that have more than one audio device.
I disabled my second sound-device (a bluetooth audio device-driver).
With only one active audio-device it worked well.

Hi,
I’ve tried your solution, but it doesn’t work… I have an external sound blaster card. Could it be the problem??
Thanks in advance,
Justine
