For external control (without soldering to buttons):
You would connect an optocoupler or transistor across each button, then trigger from Arduino. cd player diy
Regulation: Linear regulated power supplies are preferred over switching mode supplies to maintain higher sound quality. Building a DIY CD player is a rewarding
