Thought I'd have a play with Avid so downloaded Freedv to get a taste.
When I try to run it I get:
I am using onboard realtek alc883 HD audio, and have updated to the latest drivers, I have also searched the web and found it to be not an uncommon problem with plenty of info about this error but no-one has any fixes.
The page on the Avid website that did have info on this problem has been removed and there is nothing on the KB.
Although I have tried all the settings for audio input/output and speaker configuration, I would still be happy hear of anything that might help.
