[alsa-devel] [PATCH 0/2] ALSA: firewire-lib: fix miss detection from MIDI conformant data channel in AM824 format for IR context

Hi,

This patchset is a fix for a case that AM824 format is used with non-blocking transmission method in IEC 61883-1/6.

The recent changes for ALSA IEC 61883-1/6 engine brings a bug to miss received MIDI messages in the case due to wrong data block counter for calculation of multiplexed MIDI stream index. This bug mainly affects ALSA oxfw driver.
