README for alsa-driver

You can specify card support with the ALSA_CARDS environment variable. If
it's left empty the port will build all drivers. This is the default behavior
so the .footprint will mismatch if you set the ALSA_CARDS environment
variable!

If you want to set a specific card, pass the -if option to pkgmk like so:

	# pkgmk -if
	or
	# prt-get install alsa-driver --margs="-if"

This will ignore the footprint.

EXAMPLE: To download and build alsa-driver with support for the emu10k1
and intel8x0 cards, use the following:

	# env ALSA_CARDS="emu10k1,intel8x0" pkgmk -d -if
	or
	# env ALSA_CARDS="emu10k1,intel8x0" prt-get install alsa-driver --margs="-if"
