Compilation
- On your Host select ALSA compilation in Linux configuration:
$ make linux-menuconfig

- in Buildroot configuration, select the user space packages for ALSA:
$ make menuconfig
Package Selection for the target-> Audio libraries:

- save your configuration and rebuild your rootfs:
$ make
- reflash your rootfs and your Linux kernel. Go here if you need more infos on how to install Linux drivers.
nodes creation
Automatically done by Buildroot / mdev, so only here as reference.
In /dev/snd/ you should have:
mknod controlC0 c 116 0 mknod pcmC0D0c c 116 24 mknod pcmC0D0p c 116 16
