In IEC 61883-6, 8 MIDI data streams are multiplexed into single MIDI conformant data channel. The index of stream is calculated by modulo 8 of the value of data block counter. Therefore data block processing layer requires valid value of data block counter.
In recent changes of ALSA IEC 61883-1/6 engine, the value of data block counter is changed before calling data block processing layer. This brings miss detection of MIDI messages in non-blocking transmission method is used.
This commit fixes the bug by changing chached data block counter after calling data block processing layer.
