Revision 2054, 15.8 kB (checked in by jwoithe, 9 years ago)

rme: implement new ffado-mixer features needed for the FF800 - all FF800 controls should now be functional (with the same caveats as for the FF400). Fixed various bugs in ffado-mixer's FF800 code. Hopefully this doesn't break anything on the FF400.
