Vista is Not Soundcard Recording Friendly
Just a note to mention to hold onto your Windows XP computers. Seems Vista is not soundcard record friendly. Worse yet, there might not be a easy way around it. Some of your recording programs may not work and it seems that Vista was designed to be this way.
Recording with Audacity? read this. This person cannot record using Audacity with his Vista system.
Another person had some luck with enabling soundcard recording, another did not.
Here no solution was found.
Vista disables devices.
Just be aware if you buy a Vista computer, and some functions cannot be done as it was with your Windows XP computer, you'll know why. Just be aware.
