Is it an original SB128? (you can tell with 'cat /dev/sndstat': if the 
mixer device shows up as

         0: Ensoniq AudioPCI

it's an original one. A newer one will show up as something like

         AudioPCI 97 (CRY13/0x43525913)

Anyway, with the original SB128 the line level-to-zero fix is not the right 
one; instead, you can run

         /usr/lib/oss/ossmix mute.linemute on

The script /usr/local/ag/bin/setup-mixer does this.

Did the contractors find the loopback that's in the audio routing system 
itself there at Access?
