Basic audio support for the SiS 7019 Audio Accelerator as found in the SiS 55x SoC. There is currently no synth support at the moment, but audio playback and capture with two periods per buffer has seen extensive use. Arbitrary period and buffer sizes (with multiple periods per buffer) have seen light testing, but are believed to be production ready.
