FOR IMMEDIATE RELEASE


4FRONT TECHNOLOGIES RELEASES THE SOURCE CODE FOR OPEN SOUND SYSTEM


CULVER CITY, CA, June 14, 2007: 4Front Technologies is proud to announce
the release of the source code to Open Sound System (OSS) v4.0. The software
currently runs on Linux, Solaris., SCO UnixWare. and FreeBSD platforms.

OSS is a cross platform API that provides drivers for most consumer and
professional audio devices for UNIX� and POSIX based operating systems,
including Linux. Owing to its open architecture, applications developed on
one supporting operating system platform can be easily recompiled on any other
platform.


Licensing Models:

Open Sound System is now available under 3 licenses:

o GNU Public License (GPL) version 2

o Common Development and Distribution License (CDDL) for all operating
systems that have full source code available under the BSD or CDDL
licenses.

o 4Front.s commercial license for using Open Sound incompatible with
open source licenses listed above. Commercial licenses are also
available for entities not wishing to use Open Sound System under any
of the above open source licenses


What is being open sourced?

The source code includes drivers for most consumer PCI and USB audio devices
and operating system support, including binary package generation and sample
test programs. Complete documentation and API specification is also being made
available to the open source community.

A device driver kit (DDK) is also available for developers to implement cross
platform device drivers for audio hardware. This eliminates lot of redundant
work that has traditionally been required to support any hardware under multiple
Unix/POSIX operating systems.


Reasons for going Open Source:

OSS has been an open API specification with multiple implementations by
independent developer communities. This has caused problems for application
designers because there are minor differences between the implementations. The
new open source community development model makes it possible to replace the
obsolete and incompatible vendor specific sound subsystems and OSS
implementations with a state-of-the-art implementation developed by 4Front
Technologies. The goal has always been to standardize audio under POSIX
compliant systems and this includes real time operating systems and embedded
systems as well.

"We are open sourcing OSS because this provides a great opportunity for
different communities to work together to provide wider audio hardware support
for all operating systems." said Hannu Savolainen, CTO and chief architect of
Open Sound System.


Industry Reaction:

"It's great to see 4Front releasing OSS under the Common Development and
Distribution License (CDDL). It's something the OpenSolaris.community welcomes,
and it provides an opportunity to improve sound support for all OpenSolaris
distributions," says Stephen Lau, OpenSolaris board member.

"Fluendo is excited to see the open source release of 4Front Technologies
advanced OSS implementation for UNIX� and Linux. Getting a unified and advanced
sound system across all major UNIX� and Linux variants will be a big advantage
for developers. We look forward to working together with 4Front Technologies to
make sure the GStreamer multimedia framework and the Open Sound System
integrates perfectly with each other", says Fluendo Business Development
Manager Christian F.K. Schaller.

"With a long history of successful collaboration with 4Front, Creative looks
forward to working with the Open Sound System community in ensuring that
Creative Sound Blaster Live! and Sound Blaster Audigy sound cards have stable
and well-supported drivers on Linux, Solaris and BSD. The open source release
of Open Sound certainly helps our goal in providing cross-platform support for
our products," said George Thorn, director of digital media relations for
Creative Labs.


Community Portal :

A new web site with source code, API specs and forums for the developer
community has been opened at http://developer.opensound.com. For more
information and to download the binary distributions of Open Sound System,

这个声卡驱动可以解决ubuntu的alsa声卡驱动由于pcm调高而有爆音导致音效不好的问题,而且整体音量要大很多。

OSS因为以前是需要钱的。所以让alsa发展起来了。前不久才出现免费版的。

看起来oss的驱动比较强,因为好像io什么的比较基础,也就是没有alsa高级,这样更底层一点。

要钱的oss只是比免费的多带了几个高等声卡的驱动。一般人用不上。

不过最好等等看。用的人多了,遇到问题也好解决

内核没遍进OSS支持是不是就不能用

我刚刚装了这个驱动,总算告别了无声世界,播放mp3等都有了声音,而且totem上的音量调节开关也可用,但没有系统音效,面板上的小喇叭打着叉,点击就说“没有找到音量控制插件和/或设备”,登录和注销都没有声音。
我的是清华同方k100笔记本,nvidia MCP51芯片组,声卡芯片是sigmatel stac9200,用alsa我几乎把坛子里讲得方法都试过了都没有声音,用oss总算有了声音,但又有上面所述问题,请高手赐教!

安装完OSS的deb包之后,重启电脑,第一件事运行sudo soundon;第二件事右键小喇叭,打开音量控制,文件,更改设备,改成oss(注意,现在应该系统中只存在oss了,安装oss的时候它会把alsa删除);第三件事,首选项,音效,那个默认的混音器改下,高亮条选中“卷”。

不是,编译内核的时候可以连声卡驱动都不装。

装完这个声卡驱动之后一般会有这几个问题,系统无音效(无所谓,不好听),那个GNOME桌面集成的音乐播放器放歌有可能会出问题(全是噪音,gstreamer的问题?我用banshee没有问题,效果还不错,超级占内存,删之!),其他MP3播放器没有什么问题,但是基于gstreamer的就要小心了。

chaoyagami 写了:安装完OSS的deb包之后,重启电脑,第一件事运行sudo soundon;第二件事右键小喇叭,打开音量控制,文件,更改设备,改成oss(注意,现在应该系统中只存在oss了,安装oss的时候它会把alsa删除);第三件事,首选项,音效,那个默认的混音器改下,高亮条选中“卷”。
1、运行sudo soundon,显示oss is already loaded。
2、右键小喇叭,打开音量控制:显示“没有找到音量控制插件和/或设备”
3、首选项,音效,混音器一项是空的,没有东西可选。

请赐教,是什么问题,如何解决?

那你运行下sudo soundoff,如果系统会提示你有程序在运行,关闭所有的声音程序,并在系统监视器里结束掉gnome混音器的进程,再运行sudo soundoff,就会关闭声卡驱动。然后再启动一下soundon看看。还有你装的是4.0吧!

我执行sudo soundoff,直接就关闭了声卡驱动,没有其他任何提示,然后执行soundon,情况依旧。
我是ubuntu 7.04 i386版本的,内核版本是2.6.20-15,OSS版本是v4.0 build 1008

那有没有哪位兄台是7.04是安装OSS声卡驱动的呢,kinqg你的安装比较奇怪,我装OSS的时候是直接用deb包就安装上了,你还修改了一些东西,才装上。你有声音就说明硬件驱动已经启动,但是ubuntu的混音器却发现不了,混音器出了问题?
