Assuming you want to control the analogue output, couple of things...
1. It depends on the impedance of the device you want the controlled volume to go to. For speakers around 4 ohms to 8 ohms - forget it. You will have one point with full volume and the rest of the rotation will result in nearly nothing audible. For headphones with 30-odd ohms impedance, it won't be much better. However, if you are feeding it into another amplifier with an input impedance in the order of 10K or more, then a 10K pot will work. To make a simple volume control like this work, you generally need a (comparatively) low source impedance and a potentiometer and load with higher impedances. If you can wrangle the maths, you can put together a tailored solution.
2. For audio volume control, logarithmic pots are the way to go. A linear pot won't have the range of control you are used to, since our ears respond to sound intensity on a logarithmic scale.
3. If you want to control a stereo signal, you will need a dual gang pot.
