• You should be able to measure the pot's resistance between 1 and 3.
• Resistance between 1 and 2 should vary from zero when slider is towards 1 and maximum when slider is at 3.

Using linear taper on audio will result in nearly all the significant volume change occurring in the first 10$ of travel. It's usually a terrible idea.
