--with-sequencer=yes: This tells the
ALSA Driver package to build the sequencer
modules for whichever soundcards for which you are building. Most people want
them so you will usually want to leave it set to yes.
--with-oss=yes: This tells the package to
build the OSS/Free emulation modules. Again, most people
want this so it's probably best to stick with yes.
--with-isapnp=no: Most sound cards these days
are PCI and so ISA Plug and Play
support isn't needed. If you are using an ISA PnP soundcard,
it's best to say yes here. If your card is ISA, but
not PnP, it is safer to stay with 'no'.
--with-cards=all: You can tell the script just
to build the drivers for your particular sound card here. For full information
on which drivers are available see ./configure
--help. If you aren't sure which chipset your soundcard uses,
have a look in CARDS-STATUS in the
ALSA Driver source
tree. The default specified here will build all drivers.
