Can you please describe in features / bullet-points what is missing
instead of saying "X is better than Y"?

What I understand what you say is:
- I want to replace X by Y, because Y is better.
- Anything what is better in X can be added to Y.
So basically I understand that you want to replace incomplete
feature-set in X by an incomplete feature-set from Y (without knowing
what the incompleteness in either X or Y is).

I understand HPS as asking you to explain in different words what you
want to tell, as he is not understanding what you want to tell. To my
knowledge HPS is not a native english speaker (neither am I). I don't
know if you are a native english speaker or not.
As a person working in a multi-language (at least 10, with english
being the common one) environment I suggest not getting upset about
phrases like "I don't understand your english", it doesn't necessarily
mean a deficit on the receiver side of this phrase, but most often
just means both ends don't share the same language background. Often
it helps in such situations to switch from implicit ("it") references
to explicitly mention an item/feature/object/... and to use short
And to bring in some technical info (parts of "AFAIR", I may misremember...):
- The OSS code in FreeBSD was at some point in time the 4Front OSS code.
- At some point 4Front closed-source their implementation and
- At some point Ariff put in an effort to advance the OSS code in
FreeBSD which made it the best in various aspects (one of them
latency) when compared to 4Front code, Windows, MacOS and Linux ALSA.
- Then in 2006 Ryan was adding OSSv4-API compatibility to the
FreeBSD sound code as part of the Google Summer of Code, mentored by
Ariff and me.
- Since then I don't remember big API changes/improvements... HPS
worked a lot on USB audio support, userland drivers and AFAIK some
MIDI stuff as part of the userland drivers, but all that is more or
less drivers, not API... please correct me if I got this wrong; and
mav(?) worked on HDA support (also driver, not API).
Note, various aspects of the FreeBSD sound code can be tweaked by
sysctls, e.g. latency, virtual channels, direct physical access
("bitperfect"), automatic resampling, equilizer, ... (see "sysctl
hw.snd dev.pcm dev.hdaa dev.hdac" and "man sound snd_hda snd_uaudio"
and the SOUND_4.TXT of Ariff you mentioned).
And regarding your comment about SOUND4.TXT: if you read this document
carefully, you will notice that the part you quoted as being bad can
