>Description:
after load sound module with "kldload snd_driver" the player works but i don't listen nothing.
>How-To-Repeat:
      
>Fix:
with one change on the driver for this device:
on the line 132 from file /usr/src/sys/dev/sound/pcm/ac97.c add:
 
{ 0x41445368, 0x00, 0, "AD1888", ad198x_patch }, 

them recompile the kernel, and the sound is ok, but don't load automatic on boot.
