NO SOUND DURING PLAYBACK, WHAT GIVES?

[liquidmusic]

Ok here goes,
I am recording or trying to, from my cassette deck wich is hooked up to my pc.
At first I had the line out left and right
from my deck going to my pc line in sound
card with a y adapter joining the L/R prongs
from the deck. I didnt realize the adapter at the end had only one ring on it. I was getting sound and playback after recording but through only one speaker. Then someone here emailed me and told me to try an adapter with two rings, it worked, I am getting sound during recording through both
speakers but no sound during playback after
recording. I am using Goldwave latest shareware version. It appears there is recording going on because the L/R bars in
Goldwave are moving. But silence when I play
what I recorded back. Right now I am only
recording a minute or so for testing. When I
first started all this I had adapter hooked into the sound cards mic port. Way too much distortion but at least it was recording. DO
I have a faulty sound card? Bad connectors,
or am I just an idiot Here is what I have
for specs:
sound card=yamaha 0PL3-SAx WDM
Software= Goldwave 4.02
connectors= standard w/y adaptor w/ 2 rings
not sure if it's 1/8" but they are standard
equipment.
P.C= 266 mhz 96 meg ram. Win 98
Thanks one and all.
