There are two ways to use the ALSA-sound-modules. I personally prefer using the manual method, meaning that I insert the driver at startup. The ALSA-drivers were designed as loadable/unloadable modules - for instance they do not reset the mixer after loading - so you can easily use the kerneld approach.
Please do read the section Backwards Compatibility. You need it to have sound support ``the old way''.
Note: If you have a PnP audio-card, you first need to set it to the right (or at least some known) IO/IRQ/DMA. See the Plug-and-Play-HOWTO. Did you configure your Plug-and-Play-soundcard? Ok, then read on please. The main part is: do a "modprobe snd-card-<soundcard>". This should do the trick. Please note that not all distributions do include /sbin in your path. If you get a "bash: modprobe: command not found", this will most likely mean that modprobe is not in your path. Try ``/sbin/modprobe snd-card-sb16'', or try to find the modprobe utility elsewhere.
The most important difficulty is with the Crystal chipsets, for these the ALSA-drivers are not auto probing. More recent information may be acquired from the INSTALL file in the driver-directory. Two examples, then a list: Gravis UltraSound (GUS) and compatibles:
/sbin/modprobe snd-card-gusclassic
/sbin/modprobe snd-card-sb16
Please note that ALSA versions before 0.4.x sometimes had different names. You need to leave out the ``card'' part for those drivers. This is indicated by an asterisk (*).

ESS Solo-1, 128iPCI card (es1938, ESS-SOLO-1). Jonas Lofwander sent me a link to a document that will help you installing
this card - which is, basically, nothing more than
modprobe snd-card-esssolo1
... but

can be of help. If you have an IBM Thinkpad 1412 you can also refer to

These are PCI cards based on the FM801 chip.
modprobe snd-card-fm801
(*) For ALSA version 0.3.0-pre4, you need to leave out the ``card-'' part in most (not all!) of the drivernames. So ``snd-card-sb16'' becomes ``snd-sb16'', however, ``snd-card-cs4232'' remains ``snd-card-cs4232'' (modprobe snd-cs4232 will do something, but it will not produce any sound!)
(**) In older ALSA versions this driver was called ``snd-card-trid4wave'' and ``snd-trid4wave''.
If you have a non-autoprobing driver, you need to supply additional info at startup to have the driver work. More information can be found in the file INSTALL in the driver directory.
According to the INSTALL file you need to supply all the information for this driver. If you initialized the card with the isapnp-tools, you can probably get info from the /etc/isapnp.conf file for the following values:
snd_port - control port # for OPL3-SA chip
snd_wss_port - WSS port # for OPL3-SA chip (0x530,0xe80,0xf40,0x604)
snd_midi_port - port # for MPU-401 UART (0x300,0x330), -1 = disable
snd_fm_port - FM port # for OPL3-SA chip (0x388), -1 = disable
snd_irq - IRQ # for OPL3-SA chip (5,7,9,10)
snd_dma1 - first DMA # for Yamaha OPL3-SA chip (0,1,3)
snd_dma1_size - max first DMA size in kB (4-64kB)
snd_dma2 - second DMA # for Yamaha OPL3-SA chip (0,1,3), -1 = disable
snd_dma2_size - max second DMA size in kB (4-64kB)
Note that the "NN" values need to be supplied, only I do not know what would be reasonable values. I do not know if the dma size option is really required.
If you happen to have an IBM Thinkpad with this chipset, then http://www.cirs.org/patrick/index.html might be of help.
If you use the driver from 0.3.0-pre4, then leave out the ``card-'' part in the name.
According to the INSTALL file you need to supply the main port for this card. Note that with the driver for 3235/6/7/8/9 cards, the one below, I ended up supplying all information (except DMA-size), otherwise the driver did not work. So you may as well use the whole command line to insert the driver. If you initialized the card with the isapnp-tools, you can probably get info from the /etc/isapnp.conf file for the following values:
snd_port - port # for CS4232 chip (PnP setup - 0x534)
snd_mpu_port - port # for MPU-401 UART (PnP setup - 0x300), -1 = disable
snd_irq - IRQ # for CS4232 chip (5,7,9,11,12,15)
snd_mpu_irq - IRQ # for MPU-401 UART (9,11,12,15)
snd_dma1 - first DMA # for CS4232 chip (0,1,3)
snd_dma1_size - max first DMA size in kB (4-64kB)
snd_dma2 - second DMA # for Yamaha CS4232 chip (0,1,3), -1 = disable
snd_dma2_size - max second DMA size in kB (4-64kB)

According to the INSTALL file you need to supply the main port and control ports for this card. Note that with a CS4237B card, I ended up supplying all information (except DMA-size), otherwise the driver did not work. So you may as well use the whole command line to insert the driver, and not only supply snd_port and snd_cport.

kerneld is a daemon that inserts modules on request, and unloads them once
they are not in use anymore. Since I have no experience with kerneld, I
do not know if the information below is accurate. The info comes from the
INSTALL file in the ALSA-drivers package. Excellent information about kerneld
can be found in the kerneld-mini-HOWTO.
Follow these steps:

If you want to preserve OSS/Free or OSS/Linux compatibility, you need to insert one more driver: the snd-pcm1-oss driver for OSS-compatibility. Issue a
modprobe snd-pcm1-oss
