patching synthesizer to sound card

[Chuck Hallenbeck]

Hi gang,

Some of you are piping output from your speech synthesizer into
your sound card. I tried unsuccessfully to do that with
doubletalk external, using a patch cord from its headphone jack
to "line in" on the sound card. The line in is alive and works
well with other sources, and headphones work well in the
headphone jack of the synth. But there is not the slightest trace
of signal delivered to the sound card. What do I need to do to
make this work? Is there a matching transformer of some kind
required? If so, can you tell me exactly what I would need?

Thanks

Chuck
