That's correct.

Please don't get me wrong. I'm very thankful to all this feedback. I know this isn't a very thankful job to offer a very close to mainline distribution and users expect the same behavior like on Raspbian. Without yours and others feedback we wont get much further. All i wanted to say was: please don't expect too much. It took nearly a year to fix this VCHIQ corruption. I think for the audio and camera stuff, we are just at the beginning ... So please keep up this good work.
