A refreshed build of UniAud
version 1.9.22 has been made available (6/16/2010); in this release,
the driver code is based on ALSA 1.0.21. This is based on the GPL ALSA
Project from Linux and provides drivers for various sound chipsets. The
1.9 series features better support for HDA than earlier versions of
UniAud, and will eventually become UniAud version 2.0.
