you need this file:
right click on it and click register activex.
otherwise have to find installer for “indeo audio codec 2.5"
Thanks for the reply.
I didn’t try the .ax, but I did find a package that contains the Indeo audio codecs as you mentioned (and video - but I think video packages like k-lite already have those).
The last free version of the Indeo has the audio codecs as one of it’s components (I unchecked the others).
The page doesn’t make clear the audio ones are included, but they are. Works like a charm.
Hopefully this post will help someone down the line.
