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.
There are different ways how to detect, which sound card is used in your laptop:
Please report the sound chip you have found out and it's Linux status to me.
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.
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.
If you can't get a dedicated sound driver to work, you may try the pcspeaker kernel module.
|COMPAQ Armada 1592DT||Window$95 reports an ESS(http://www.esstech.com/) 1878 PnP sound card, which should be Soundblaster and SoundblasterPro16-Bit compatible. For details see COMPAQ Armada 1592DT. The 2.1.132 kernel detects:||own research|

|Fujitsu LifeBook C-6310||This model has the same soundcard as the Lifebook 5110c, beiing the Yamaha YMF744B. "After having installed kernel 2.4.17 (with a lot of improvements on the ymfpci-driver) I got the sound card working without any further problems."||M. G. (Michael) de Bruin <m.g.debruin_at_kpn.com>|

|HP Omnibook 3100||
SoundblasterPro16-Bit compatible works (without midi yet), take the SB driver in the kernel:

|HP Omnibook 4150||"The Magic Wave 3d is a NeoMagic sound card it works with the OSS OPL3-SAx driver I solved the problem .. After adding card/device: "Neomagic NM2000 PCI *BETA*" and "4Front Tech. Virtual Mixer" in 'soundconf' from opensound my box always reboots. The clue was to also enable "Generic 256AV *NMA2*" card/device in 'soundconf', and now it works."||<debian-laptop_at_lists.debian.org> 01/2000|
