I have an Opti-Audio 16  (MAD 16) sound card, which was detected when 
I ran sound_setup: unfortunately, its output is very quiet, even with 
the volume turned up full, and drops out completely quite regularly.  
Could anyone suggest what might be going wrong? I thought maybe it is 
clashing with another device.  Here's my /proc/interrupts file:-

  0:    2398106          XT-PIC  timer
  1:      32887          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  5:    1746248          XT-PIC  eth0
  7:          2          XT-PIC  MAD16 WSS
  8:          2          XT-PIC  rtc
  9:          6          XT-PIC  MPU-401 UART
 12:     440681          XT-PIC  PS/2 Mouse
 13:          1          XT-PIC  fpu
 14:     399610          XT-PIC  ide0
 15:      50348          XT-PIC  ide1
NMI:          0
ERR:          0          

This looks ok to my novice eyes, but perhaps there is something wrong. 
 Here's the /dev/sndstat file as well in case that helps:-
