If we build it they will come

It looks like the jack reporting API for ALSA which just got merged into the mainline kernel for inclusion in 2.6.28 already has its first user – code from Matthew Ranostay supporting the jack detection in Sigmatel HDA codecs was just queued for merge in the next merge window. Admittedly, the jack reporting API has been available in ALSA git since July but it does look like it is just impressively fast adoption after the mainline merge.

Still, a long way to go before user space can start to rely on knowing if things are plugged in or not.
