Hi, I recently submitted two patches for ALSA kernel stack that will guarantee wake_ups to happen at each periodic interrupt. Currently that is not the case when avail_min is greater than period size. The patch doesn't seem to cause regression but might break applications that depend on non-standard use of ALSA API. Takashi Iwai noted that PulseAudio might complain about the change (not that PulseAudio use non-standard methods). Could someone please confirm if the two patches might cause regression for PulseAudio?
