Just like each vendor ships a WAV and/or a WDM/DirectSound
driver with each sound card, for use by the Win32 API (wavOutOpen
or IDirectSound), a vendor can ship an ASIO driver which works
with the ASIO API.
Typically, ASIO drivers for a card will also support WAV and/or
WDM for use as a regular sound card under Windows, although you
often can't do both at the same time. The latest Echo drivers are
nice in that you can set aside some channels for Win32 and some
for ASIO if you want. Myself, I put a SoundBlaster Live! in for
games, and use the Layla for music, and tell Win32 to never use
the Layla and ASIO to never use the SBL!.
