From the ALSA wiki
AudioScience PCI soundcards
HPI drivers and patches against the standard ALSA source are available from http://www.audioscience.com/internet/download/linux.htm
The HPI driver supports the full functionality of the cards.
The Alsa driver is layered on top of this driver, and supports recording and playback, and access to volume, level, multiplexer, channel mode, meter and sampleclock controls. (More esoteric controls like microphone, AESEBU attributes, equalizer etc are not currently supported)
