[Asterisk-Users] No Audio from Console but mpg123 from shell works fine.

[Jonathan k. Creasy]

I get audio from mpg123 at the command line but when I load up asterisk
and try to get audio from the console it looks like it's working, and
even pauses like it is playing the file but there is no audio coming
from the speakers. 

I have searched and looked through the archives and tried to fix this
but I have had no success. This is an onboard Intel card (AC'97) and I
also tried an SB Live card with the same result.
