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. |
5 | * SC-6600 and SC-7000 cards are also supported. They are based on |
6 | * CompuMedia ASC-9408 chip and CS4231 codec. |
