If the volume control isn't working like you would expect, try turning your A5+s off and then back on. Since the A5+ volume control is a digital encoder, it uses a microprocessor to attenuate the volume. Like most sensitive electronics if left on for an extended period of time, you may eventually experience unexpected operation so they may need to simply "reboot".
If the volume knob feels loose or the volume knob doesn't "click" when pressing it in, it sounds like the nut that holds the volume pot in might just be loose. This can be accessed and tightened without opening the speakers up. Try this:
- Pull the plastic volume knob off the volume pot. Depending on how tight it's on, you might be able to pull it off with just your fingers. If not, look for something fairly flat and preferably plastic with soft edges to pry it with.
- Use a deep well 10mm socket (or socket driver) to tighten the nut around the volume pots shaft.
- Press the plastic volume knob back over the volume pot's shaft, and retest.
