Hi

It looks like ALSA support the Cmedia CMI8738 soundcard
(http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=C-Media&card=.&chip=CMI8338%2C+CMI8738%2C+CMI8768&module=cmipci).

You can get info about the module with this command /sbin/modinfo
snd-cmipci or find the ALSA-Configuration.txt document in the the ALSA
source. In the ALSA-Configuration.txt you get information about module
options. It looks for me that the SDIF port only works for the model
033 only. Check also out the Alsa bug reporting webpage about this
card

Module snd-cmipci
  -----------------

    Module for C-Media CMI8338 and 8738 PCI sound cards.

    mpu_port - 0x300,0x310,0x320,0x330 = legacy port,
          1 = integrated PCI port,
          0 = disable (default)
    fm_port - 0x388 (default), 0 = disable (default)
    soft_ac3 - Software-conversion of raw SPDIF packets (model 033 only)
                  (default = 1)
    joystick_port - Joystick port address (0 = disable, 1 = auto-detect)

    This module supports autoprobe and multiple cards.

    The power-management is supported.
