Paul Smedley has some test builds of UniAud where the HDA code has been updated to ALSA 1.0.11, 1.0.12, 1.0.13, 1.0.14, 1.0.15, and 1.0.16. Note that the current state of HDA support in UniAud 1.1.x is poor, and may be disabled for the 1.1.4 release if these test releases do not produce good enough results.
