What kind of cable are you using to plug into your soundcard? You should be using a 1/8" stereo male plugged into the line-in of soundcard, to two mono plugs that go from the output of the tascam(not familiar with the 414, RCA's or 1/4"?) Check the balance control in the windows volume panel. Double-click the speaker icon and see that the line in volume is up, and that the line in balance is in the center.
Outside of that.
I've never heard of Riptide before, unless it's some highend mega-bucks sound card.
Recording through the line-in is the normal procedure. Is the sound card integrated into the motherboard?
If all else fails, I'd suggest taking the rip-tide out and putting in a Creative Labs/Ensonic soundcard. These are fairly cheap ($30) and will work much better than what you have.
If it's built-in audio, hopefully you can disable it through BIOS or at worst Device Manager.
For music you should be using CD-R, write-once. You can use CD-RW, but they don't play very well (usually not at all, except for a rare instance
) in other cd-players, and you have go through the format crap.
