line-in input doesn't record

[Bryan Bolden <bbolden@UU.NET>]

hello all!!  I am trying to begin recording/sampling of voice coming in
from my line-in jack.  I have a tape recorder connected (through the tape
recorder' s earphone jack) to the line-in of my sound card (is that right).
 now when I press play on the tape I do hear the voices on tape through my
external spekers but when I test the recording with :

dd if=/dev/audio of=/tmp/audio_test
and then:
cat /tmp/audio_test >/dev/dsp

all I hear is the sound from the mic input.  I have adjusted the line-input
sound level through a mixer at a higher leven that the mic's level but I
don't hear anything from the sampled audio from the tape despite hearing it
from my external speakers.  any suggestions?

thanks!
