There's a couple of things I can do here: 1) Post my ideas for selecting/controlling VCO associated with PCM _soon_ 2) Come over on Tuesday and join the mini summit 3) Both! I'm pretty new to ALSA, so I can only realistically contribute to the scheduled stream trigger discussion, although the Configuration/ASoC stuff will be relevant to my crowd too. If no-one has a major objection to a rep from the ALSA-newbie community, I'll see if I can come over :) Either way, I'll post my VCO ideas to the list ASAP. Cheers, Tim
