Addition: I tought I once made already a pull request of that so probably it flew out or is already incorporated...

just took a quick look at these patches. looking good in general, but can you squash the audio related commits into 1 (you've changed the signature of AudioEnable() in 1 patch and reverted the changes in the next one for instance).
same for the Teufel vendor id ones.

2082445 contains some things that are local to your system that should be removed. from the looks of it, it's just the size of the buffer that needed fixing up.

I'll give it another proper review after it's been cleaned up and will merge it one once it's ok, thanks.

of course.
I already thought you might ask for something like that, but I wanted to know whether it will be worth the effort ;o)
I will try to make things "topic related".
