Hi all,
this is to clarify (for me, anyway) the status of

audio drivers present in the (recently GPLed) OSS.

http://www.opensound.com/osshw.html
What is the relation of OpenBSD's audio drivers to the OSS project?

What, if anything, does opensourcing (GPL, I know) their code mean for

our audio drivers? In particular, does that mean (future) support for

the high-end soundcards such as M-Audio Delta?
	Thanks

There's work in progress on adding support for Delta cards (1010,

1010LT, 66, 44), and required features to make them usable (32bit

encodings, 12 channel capture, higher sample rate, etc...)
-- Alexandre

Where can I get in touch with this work and possibly test it?

Is anything commited -> available in curent?
	Thanks
		Jan

it's not in cvs yet. Below's a diff you can test. It probably only

works on delta-1010 and delta-1010LT cards and it's enabled on i386

only. The diff adds support for 32bit samples and 10 channels.

Neither capture nor mixer are implemented yet. Feel free to contact

me privately if you have questions on that.
Anyway if you have any delta card, i'm interested in seeing your

card's eeprom contents (in dmesg), the kernel should be compiled on

i386 with these options:
	option  ENVY_DEBUG
	envy* at pci?

	audio* at envy?
Also, let me know if you notice regression with other audio

drivers.
cheers,

That code is not free enough for us to use, and therefore we don't

use it.

Hi,
OpenBSD uses an implementation of the Sun audio system, which is a

different system to OSS alltogether. I don't know where it came from,

it is probably not based upon any of sun's code due to licensing.
As for the M-audio Delta, not sure about that particular card, but I

have a M-audio mobile pre (usb), which works fine under OpenBSD. I'm

not sure if that's an indication that M-audio aim to support UNIX, or

just a coinsidence. Try dropping them an email?
In all fairness, you would be better off using a nice piece of kit

like that on Windows or MacOSX (/me ducks), because the audio editors

for NIX are slightly limited in comparison to say Cubase or Pro-tools.
Thanks
