Hello Hans, If you can find a few minutes, please take a look at the following tree, where I added initial support for including the ALSA devices in the MC enumeration. I also did a bit of cleanup on your example tool, properly showing the fields associated with the given node type and subtype (before it was always showing fields for the V4L subtype). http://kernellabs.com/hg/~dheitmueller/v4l-dvb-mc-alsa/ I've implemented it for em28xx as a prototype, and will probably see how the code looks when calling it from au0828 and cx88 as well (to judge the quality of the abstraction). Comments welcome, of course... Devin -- Devin J.
