I am using a usb-audio device.

Bus 003 Device 001: ID 0000:0000 
Bus 003 Device 002: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
Bus 002 Device 002: ID 13fe:1f00 
Bus 002 Device 001: ID 0000:0000 
Bus 004 Device 001: ID 0000:0000 
Bus 001 Device 001: ID 0000:0000 

I am using this as my asound.conf file

       pcm.usb-audio {
          type hw
          card 0
       }
      
       ctl.usb-audio {
          type hw
          card 0
       }

I am using debian etch  2.6.18-6-486 #1 Fri Jun 6 21:47:01 UTC 2008 i486 
GNU/Linux

It works for a couple times then I get the seg fault. I am using the 
Console output from asterisk.

help? Thanks,

Jerry
