USB AUDIO
« on: July 04, 2010, 02:30:52 am »
I have written code for a small microcontroller to do USB AUDIO (speakers) and it works on an XP machine and not Vista or Windows 7, I have narrowed it down to a lot of people online talking about how their USB audio devices all stopped working on Vista and that it was a known fact and had to do with Microsoft DRM, somehow MS does not like the device as it is not seen as DRM worthy. I wonder if anyone knows the exact reason and what you need to add to the USB AUDIO device to make Vista like it? (modify the USB descripto????)

Thanks!

You've likely seen it, but there is a hotfix:

The setupapi files might also offer a clue.
