document only applies to the sound drivers included with the standard

x86 platform.</P

>The sound driver should also work with most sound cards on the
|
|
Alpha platform. However, some cards may conflict with I/O
|
|
ports of other devices on Alpha systems even though they work
|
|
perfectly on i386 machines, so in general it's not possible to tell if
|
|
a given card will work or not without actually trying it.</P

PowerPC version of Linux, but it should be supported in

|
future.</P

|
>Sound can be configured into the kernel under the MIPs port
|
|
of Linux, and some MIPs machines have EISA slots and/or built in sound
|
|
hardware. I'm told the Linux-MIPs group is interested in adding sound
|
|
support in the future.</P

|

>The Linux kernel includes a separate driver for the Atari
|

and Amiga versions of Linux that implements a compatible

subset of the sound driver on the Intel platform using the built-in

|
sound hardware on these machines.</P
|

><P
|

>The SPARC port of Linux currently has sound support for
|
|
some models of Sun workstations. I've been told that the on-board
|
|
sound hardware works but the external DSP audio box is not supported
|

because Sun has not released the specifications for it.</P

different bus architectures available. Here is a brief overview of the

more common types and their distinguishing features.</P

><P
|
|
><EM
|
|
>ISA bus</EM
|
|
> cards are among the oldest sound cards
|
|
using the original (non Plug and Play) ISA bus. These typically use
|
|
jumpers to select hardware settings for I/O addresses, IRQ, and DMA
|
|
channel. You are unlikely to find any of this type manufactured today.</P
|
|
><P
|
|
><EM
|
|
>ISA Plug and Play</EM
|
|
> cards use the extended version
|
|
of the ISA bus that supports software identification and configuration
|
|
of card settings. Few of these, if any, are still being manufactured.</P
|
|
><P
|
|
><EM
|
|
>PCI bus</EM
|
|
> cards use the higher bandwidth PCI bus
|
|
which provides identification and configuration of cards in
|
|
software. The majority of sound cards manufactured today now use
|
|
PCI. Most motherboards that provide on-board sound hardware also make
|
|
use of the PCI bus.</P
|
|
><P
|
|
><EM
|
|
>USB</EM
|
|
> is a newer bus architecture for external
|
|
hot-pluggable devices. In theory USB bus sound cards could be
|
|
developed, but I am only aware of USB-bus speakers being sold
|
|
currently.</P

>The following sound cards are supported by the Linux kernel

sound driver. Some of the items listed are audio chip sets rather than
|
|
models of sound cards. The list is incomplete because there are many
|
|
sound cards compatible with these that will work under Linux. To add
|
|
further to the confusion, some manufacturers periodically change the
|
|
design of their cards causing incompatibilities and continue to sell
|
|
them as the same model.

compatible enough to work with the Linux SoundBlaster driver. These

SoundBlaster cards made by Creative Labs, which use Creative's custom

chips (e.g. SoundBlaster16 Vibra), MV Jazz16 and ESS688/1688 based

cards generally work with the SoundBlaster driver. Trying to use a

SoundBlaster Pro compatible 16 bit sound card with the SoundBlaster

driver is usually just a waste of time.</P

>Sound support in the Linux kernel was originally written by Hannu
|
|
Savolainen. Hannu then went on to develop the Open Sound system, a
|
|
commercial set of sound drivers sold by 4Front Technologies that is
|
|
supported on a number of Unix systems. Red Hat Software sponsored Alan
|
|
Cox to enhance the kernel sound drivers to make them fully
|
|
modular. Various other people also contributed bug fixes and developed
|
|
additional drivers for new sound cards. These modified drivers were
|
|
shipped by Red Hat in their 5.0 through 5.2 releases. These changes
|
|
have now been integrated into the standard kernel as of version
|
|
2.0. Alan Cox is now the maintainer of the standard kernel sound
|
|
drivers, although Hannu still periodically contributes code taken from
|
|
the commercial driver.</P
|
|
><P
|
|
>The commercial Open Sound System driver from 4Front Technologies tends
|
|
to be easier to configure and support more sound cards, particularly
|
|
the newer models. It is also compatible with applications written for
|
|
the standard kernel sound drivers. The disadvantage is that you need
|
|
to pay for it, and you do not get source code. You can download a free
|
|
evaluation copy of the product before deciding whether to purchase it.

Linux Sound Architecture</EM

> (ALSA) and has resulted in what they

believe is a more generally usable sound driver that can be used as a

replacement for the built-in kernel drivers. The ALSA drivers support

a number of popular sound cards, are full duplex, fully modularized,

A separate "Alsa-sound-mini-HOWTO" is available which deals with

compiling and installing these drivers. The ALSA drivers may move into

the standard Linux kernel as part of the 2.5 kernel development.</P
