UniAud versions 1.9.24 and
2.1.1 have been made available (7/28/2010); in these releases, the
driver code is based on ALSA 1.0.21 and 1.0.23, respectively. This is
based on the GPL ALSA Project from Linux and provides drivers for
various sound chipsets, including HDA, AC97, and PCI cards. Note that
there are some known problems with the 2.1.x series, such as "pops" at
the end of WAV files.
