The card is always fully initialised, the driver (kernel) previously
wrote all these zeroes to mute all channels. It's the default state to
prevent unintended output on any channel.

Speaking of which, I'm currently hacking a matrix mixer for RME
cards:
It's a toy project to improve my rotten C++ skills, so I chose gtkmm.
I still need to add support for double/quad speed modes and maybe polish
the GUI a bit, but otherwise, it's fully functional.
In contrast to hdspmixer, it doesn't duplicate the same
information/constants over and over again, every RME model is its own
C++ class inherited from a universal base class and only defining the
relevant bits (number of I/O/P channels, channel names).
In other words, it's a lot more readable, but since I wrote it, I'm
biased. ;)
Cheers
