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=20=20
feature-set=20in X by an incomplete feature-set from Y (without knowing=20=
=20
what=20the incompleteness in either X or Y is).

I understand HPS as asking you to explain in different words what you=20=20
want=20to tell, as he is not understanding what you want to tell. To my=20=
=20
knowledge=20HPS is not a native english speaker (neither am I). I don't=20=
=20
know=20if you are a native english speaker or not.
As a person working in a multi-language (at least 10, with english=20=20
being=20the common one) environment I suggest not getting upset about=20=20
phrases=20like "I don't understand your english", it doesn't necessarily=20=
=20
mean=20a deficit on the receiver side of this phrase, but most often=20=20
just=20means both ends don't share the same language background. Often=20=
=20
it=20helps in such situations to switch from implicit ("it") references=20=
=20
to=20explicitly mention an item/feature/object/... and to use short=20=20
phrases.
And=20to 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=20=20
FreeBSD=20deviated.
- At some point Ariff put in an effort to advance the OSS code in=20=20
FreeBSD=20which made it the best in various aspects (one of them=20=20
latency)=20when compared to 4Front code, Windows, MacOS and Linux ALSA.
- Then in 2006 Ryan was adding OSSv4-API compatibility to the=20=20
FreeBSD=20sound code as part of the Google Summer of Code, mentored by=20=
=20
Ariff=20and me.
- Since then I don't remember big API changes/improvements... HPS=20=20
worked=20a lot on USB audio support, userland drivers and AFAIK some=20=20
MIDI=20stuff as part of the userland drivers, but all that is more or=20=20
less=20drivers, not API... please correct me if I got this wrong; and=20=20
mav(?)=20worked on HDA support (also driver, not API).
Note, various aspects of the FreeBSD sound code can be tweaked by=20=20
sysctls,=20e.g. latency, virtual channels, direct physical access=20=20
("bitperfect"),=20automatic resampling, equilizer, ... (see "sysctl=20=20
hw.snd=20dev.pcm dev.hdaa dev.hdac" and "man sound snd_hda snd_uaudio"=20=
=20
and=20the SOUND_4.TXT of Ariff you mentioned).
And regarding your comment about SOUND4.TXT: if you read this document=20=
=20
carefully,=20you will notice that the part you quoted as being bad can=20=
=20
be=20disabled.
Bye,
Alexander.
