Thank you, Winfried!! :D

+ an iio-backend for Jack2 to use the internal AD's
in jack for processing sensor data in PD ;-))) but tricky

I'm quite interested in this. Will you make this available in your blog?

+ but with a trick: filtered 5V supply for the USB-card not the USB power
it seems to get reasonable quality
(They have all the same chips like expensive USB cards: C-Media)

You mean hooking up the sound card to a different powers supply? I guess the ones you are using are not USB powered?

and release the PD-lib (GPIO,AD,I2C,... interfacing) for these
devices.

Awesoooommeee!!! :D :D
