Thanks a lot! I was waiting for this. And I'll observe an ALSA-FW development (I mainly intersted in RME driver).

Hi,
This patchset is to add a new driver for RME Fireface series. This is still working in progress but currently the new driver support MIDI functionality.
Unfortunately, ffado library can disturb this functionality. In RME::Device::init_hardware() function, the library sends a write transaction to 0x0000801003f4 with invalid value as higher part of address in IEEE 1212 or ISO/IEC 13213. This is a worst case I describe in patch 03.
A workaround is to load this module after running ffado library. This module sends write transactions with valid values and regain MIDI functionality.
I think it better that FFADO developers fixes the bug as long as they doesn't support MIDI functionality.
