Awesome. 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
