ALSA (Advanced Linux Sound Architecture) is a modularized architecture which
supports quite a large range of ISA, USB and PCI cards.\n
It also provides a much higher API than OSS.\n
To use alsa, one can either use:
- the old compatibility OSS api
- the new ALSA api that provides many enhanced features but requires using the ALSA library.
