2 * Driver for Gallant SC-6000 soundcard. This card is also known as
3 * Audio Excel DSP 16 or Zoltrix AV302.
4 * These cards use CompuMedia ASC-9308 chip + AD1848 codec.
c2828661
KH		 5 * SC-6600 and SC-7000 cards are also supported. They are based on
6 * CompuMedia ASC-9408 chip and CS4231 codec.
