8. The Sound Drivers
Note that there was a rewrite of a lot of the sound core and related drivers. The older stuff is generally called
`OSS' and the newer is called `ALSA'. The intention is to drop the OSS stuff eventually. To avoid name
conflict, the ALSA stuff generally has `snd−' as a prefix to all the boot parameters.
Note that each driver has its own individual boot argument (very old kernels used a shared sound=). Also,
generally no defaults are set at compile time (i.e. you must supply a boot argument for older non−PNP ISA
cards to be detected.) Your best source of information for your card is the files in
linux/Documentation/sound/.
