Picade speakers

Built my Picade works brilliantly but no sound, very quiet with headphones plugged into Pi, have searched a lot of forums looking for an answer, most of which involve a keypad which I haven’t got, changed cables and followed lots of advice but nothing seems to work, what I would like is some help in simple easy to understand instructions, bear in mind I’m an OAP who last dabbled in electronics 50 years ago when the transistor was new, so please be gentle with me, Bob Ashford


I’m assuming you’ve tried the buttons on the left hand side of the picade. One nearest the back is volume up from memory.
