OSSv4 and FreeBSD?

Roberth · Nov 16, 2008

Why doesn't FreeBSD adapt to OSSv4 as sound system? It broaden the sound card compability a lot.

trasz@ · Nov 16, 2008

OSSv4 is available in the Ports Collection, as audio/oss.

Roberth · Nov 16, 2008

Yes I know, but why not use it as default sound system?

What for if actual FreeBSD's OSS implementation works great?

As you can see OSS development in FreeBSD doesn't stand still.

There are probably licensing issues as well.

praxis · Nov 16, 2008

thanks, i was always wondering about this too.

OSS4 from 4Front is also released on BSD license (along with CDDL and GPL).

praxis · Nov 16, 2008

oss4 is released under the bsd license. http://www.4front-tech.com/forum/viewtopic.php?t=2411

Then why is there so few soundcards supported?

oliverh · Nov 16, 2008

>Then why is there so few soundcards supported?

Because of man power, time, documentation, hardware, money? Furthermore development of a sound system is more than just delivering drivers. First there is a proper infrastructure, then there are the drivers.

Just an example, my Soundblaster Audigy 4 is not supported by OSSv4 but by emu10kx.

praxis · Nov 16, 2008

So, why doesn't freebsd adopt oss4 infrastructure and then build specific drivers on top of that? It just seems oss4 provides a way for all unix/linux flavors to have the same api, which would possibly result in more cross-platform audio applications.
I by no means know the technicalities involved; I am just wondering.

Kitche · Nov 17, 2008

probably most likely the same reason why Sendmail is in base and not Postfix

but why complain if ossv4 is not in base, if it's in ports

>So, why doesn't freebsd adopt oss4 infrastructure

Maybe it has got already a very good infrastructure? Ariff did a huge work on it. And this http://4front-tech.com/hannublog/?p=14 could be a problem too. You could call OSSv4 development more or less 'dead'.

Roberth · Nov 17, 2008

But why can't FreeBSD as mentioned, adapt the structure, and also adapt the drivers do furthere developement on them?

trasz@ · Nov 17, 2008

Because our own is much better. Things like resampling or software mixing are implemented much better in FreeBSD implementation of OSS than in OSSv4. Also, OSSv4 needs some abstraction layer on top of the actual operating system kernel APIs, as every operating system does things like locking in a different way. FreeBSD OSS is written to use the kernel interface directly.

Another thing is API. AFAIK there is ongoing work to support OSSv4 API in FreeBSD OSS implementation.

And what about 5+1, 7+1 ... ALSA ?

aragon · Nov 17, 2008

ALSA is a linuxism. I wouldn't hold your breath for it in BSD (outside of the emulation layer, at least).

praxis · Nov 17, 2008

thanks trasz@, thats all I was wondering about.

As trasz@ said and if there is anything useful in it I'm sure some FreeBSD dev will adopt it. Furthermore as far as I know not all of the drivers in OSSv4 are free.

Alsa will never be ported to any Unix

This is why

Solaris port of OSS is really fantastic. I have not checked its license. If
it is CDDL obviously it is not an option but if it is an academic style license
(BSD, MIT) that should be worth of considering as a replacement for FreeBSD version
of oss.

What an obsolete information, I should noticed this much much before.

Look for development in 8.0: http://wiki.freebsd.org/8.0TODO

and http://people.freebsd.org/~ariff/SOUND_4.TXT

richardpl · Jun 4, 2009

With this change that is in progress for FreeBSD 8.0 RELEASE
OSSv4 becomes toy for kids.
