Since my personal opinion is to sync with the official OSS API, I'm very
pleased to hear that. What kind of assistance do you offer?

Since those apps which use ALSA most likely will be part of the ports
collection but not of the base system, I think this isn't really needed to
be adopted by us. SALSA can just be part of the ports collection too.
I put it on my TODO list to have a look at it, but because of some
constraints it may take a while (maybe a month) until I can look at it.

Do you have a document which highlights the differences between the v4 and
the previous API?
Regarding the general problems of improving our sound subsystem: I think the
largest problem is, that we don't have an overview what we have and how it
fits together (at least I'm not aware of one). This reduces the amount of
people which want to try to work on it.
At http://www.leidinger.net/FreeBSD/src_docs/dev_sound.pdf (~11 MB) I've put
a doxygen generated document online which at least visualizes the call
graphs and so on, but this is of course in no way anything near what we
