Thanks in advance,
Get ahold of a USB or Firewire audio interface - M-audio makes a few good ones that are decently priced.
However, in the meantime, a quick fix that I use to get mediocre sounding recordings (still scratchy and muddy, but at least without the hum) is to record a sample of the hum without anything else, then invert polarity and mix it back into the recorded track. At the correct phase, the hum cancels out.
(Signal + hum) + (-hum) = signal
Quality still sucks, though.
Are you sure that you have the right cable and/or connectors?
Are you sure that mic and cable you are using are problem free?
Have the mic and cable been verifed to work problem free somewhere else?
Laptops and their mini jacks, unpredictable input level matching, impedance, and lousy sound cards are terrible for recording as is.
If you want better sound, use an external audio interface (PCMCIA or USB) to connect your audio I/O's. The EB Tech won't help because it is an in line device. The external interface should eliminate all your noise problems, and allow you to use XLR mic connections too, depending on which interface you choose.
CRT on the other hand... ug.
I don't see how the FCC lets these manufacturers off the hook on allowing internal noise. Your vacuum cleaner is tested not to affect the TV, laptops internal components should follow the same tests.
Recording on something as compacted as a laptop introduces noise inside the box itself - when the signal is passing through the sound card components.
