 *  Driver for Gallant SC-6000 soundcard. This card is also known as

 *  Audio Excel DSP 16 or Zoltrix AV302.

 *  These cards use CompuMedia ASC-9308 chip + AD1848 codec.

 *  SC-6600 and SC-7000 cards are also supported. They are based on

 *  CompuMedia ASC-9408 chip and CS4231 codec.

 *  I don't have documentation for this card. I used the driver

 *  for OSS/Free included in the kernel source as reference.
