And sorry for the late reply, it took time to process backlogs after my vacation. Here are the lists of topics I had in my mind: - Status-quo; Recap what's been added/changed recently from API/ABI POV - USB-audio - PCM handling; it's been a known issue regarding the unnecessary latency with USB-audio. Do we need a new operation mode? - Dynamic device handling, e.g. HDMI/DP; currently we deal with only the card-level disconnection, but it doesn't work well with devices having multiple digital ports. The disconnected state also leads to a problem with PulseAudio. - Year 2038 problem; PCM API changes RFC were posted recently on alsa-devel, and we have timespec in other APIs (rawmidi and timer), too. - ASoC hotplug support; recent works / reports from Morimoto-san revealed the lack of hotplug support in ASoC. - Drop of obsoleted drivers / features; time to think of diet? - API/ABI documentation; do we have a better shape than before? How can it be improved? - ALSA user-space stuff releases; maybe we should stick with more strict release schedule? thanks, Takashi
