Paul,

**** List of CAPTURE Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: VT1708B Analog [VT1708B Analog]
  Subdevices: 2/2
  Subdevice #0: subdevice #0
  Subdevice #1: subdevice #1


I think your correct from the above.


however, what do I do about it.
I tried setting:
input_device=hw:0,0
output_device=hw:0,3

and I still get errors:
^[[1;30;40m  == ^[[0;37;40mParsing '/etc/asterisk/alsa.conf': Found

How would I correctly set this up?
I dont need audio in at all. Just out.
