TuxMobil: Sound Card Support for Linux with Laptops and Notebooks

This overview is a side effect of my work with the Linux Mobile Guide from which I partly quote.

The Linux status of the sound cards reported below, is changing and improving. Therefore, if a sound card is reported as "unsupported" you should give it a try. Why is this survey valuable though: To encourage people which want to buy a "working" stated machine (remember: no guarantees) and to collect technical information (what sound chips are used) about different models.

For a list sorted by sound cards see the list of sound cards.

Linux Compatibility Check

There are different ways how to detect, which sound card is used in your laptop:

Read the specs carefully.
One way to check this, is to compile the different sound drivers into the kernel and check whether they are detected or not. The best way to do so, is to compile them as modules because it's easier to load different parameters such as interrupts and IO ports than. For the new 2.2.x kernels, read the /usr/src/linux/Documentation/sound/Introduction document by Wade Hampton. This document may help you get started with sound.
If the sound card is a PCI device lspci might help.
If it's a PnP device lspnp might help.
You might find your laptop included in the list below. Since I just have started it, it's very small yet.
As a last resort you may look on to the inscription of the sound chip itself.

Please report the sound chip you have found out and it's Linux status to me.

Survey Sound Drivers

Many new laptops come with 16-bit sound. But MWave and some other sound technologies won't work or are very hard to get working, e.g. booting to DOS, loading a driver, then using the soundcard as a standard SB-PRO. So you might need a commercial sound driver. With the recent announcement of Linux support by IBM, it would be GREAT if IBM supported the MWave under Linux (hint, hint...). As a last resort you may try the speaker module pcsnd, which tries to emulate a soundcard.

Kernel Sound Driver by Hannu Savolainen, read the /usr/src/linux/Documentation/sound/Introduction
ALSA Advanced Linux Sound Architecture". The Advanced Linux Sound Architecture aims to: be a fully-modularized sound driver which supports kerneld/kmod, ensure compatibility with most binary OSS/Lite applications, create an ALSA Library (C,C++) which covers the ALSA Kernel API for applications, and create ALSA Manager, an interactive configuration program for the driver.
UNIX Sound System Lite / OSS provides commercial sound card drivers for most popular sound cards under Linux. These drivers support digital audio, MIDI, Synthesizers and mixers found on sound cards. These sound drivers comply with the Open Sound System API specification. OSS provides a user-friendly GUI which makes the installation of sound drivers and configuration of sound cards very simple. OSS supports over 200 brand name sound cards. OSS drivers provide automatic sound card detection, Plug-n-Play support, support for PCI audio soundcards.
pciaudio(http://www.baycom.org/~tom/) is a set of drivers for popular PCI soundcards. The drivers support OSS compatible mixer and PCM (wave) interfaces. It currently supports the Ensoniq ES1370/Ashai Kasei AK4531 and S3 SonicVibes adapters. Are these cards used in laptops?
Aureal has announced the first Vortex Linux driver. The driver supports the Vortex 8830, 8810 and 8820 chips. Which are used in Aureal SQ2500, Aureal SQ1500, Diamond MX300 and Turtle Beach Montego cards. Are these cards used in laptops?
OpenAL(http://www.openal.org/), the Open Audio Library, is a joint effort to create an open, vendor-neutral, cross-platform API for interactive, primarily spatialized audio. OpenAL's primary audience are application developers and desktop users that rely on portable standards like OpenGL, for games and other multimedia applications. OpenAL is already supported by a number of hardware vendors and developers.

PCMCIA Soundcards

Dave Hinds on linux.dev.sound, comp.os.linux.hardware, comp.os.linux.portable: "No PCMCIA sound cards have Linux support. Most new laptops have built-in sound these days, so there has not been much call for PCMCIA sound card support. Also... Linux doesn't implement support for DMA from PCMCIA devices, and some PCMCIA sound cards seem to require that."

The only exception I know:

Bullet II made by Communication Automation Corporation - CAC(http://www.cacdsp.com). The driver is written by Jont B. Allen: "One serious problem is that the card cost almost 1K$, which is why there isn't much acceptance. However, if two channels is adequate, and you might want floating point DSP, there is no other card.

The codec is of very high quality, Sigma Delta 16 bit converter.

We need more sound cards. Typically the audio input in laptops sucks. The output can be quite good, but the input is typically useless. This card solves that problem.

I feel we need to nurture such special devices. I just got a call last week that ARPA/DARPA is using my driver for IP speech coders. They are attempting to convert it from 2.0.x to 2.2.x, and are having some problems, and thus contacted me."

Other currently not supported cards you may find at my page about "Unofficially" Supported PCMCIA Cards.
