UniAud versions 1.9.26 and 2.1.3 have been released (4/14/2011) on netlabs.org FTP;
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. In addition, the cause
of repeating system sounds has been found to be a bug in IBM's SND.DLL, and a workaround created.
