Hi All,
In the next few days I'm going to installing a panel mount 3.5mm audio jack to a 464 that has destroyed solder pads. I must confess I botched the repair 25 years ago as a kid and have been reunited this xmas to discover the horror.
Is there a test program I can use to determine if I wired the channels correctly eg L/R after the repair?
Thanks :)
PS I should mention I have a M4 board from Duke to test
Aren't channels fixed, L/R?
How badly did you destroy the original socket? You can always superglue the socket in place and run jumper wires, rather than making a new hole in the case.

You can test the channels with simple SOUND commands in BASIC:
SOUND 1,440,100,15 should produce a sound in the right speaker.
SOUND 2,440,100,15 should produce a sound in both speakers.
SOUND 4,440,100,15 should produce a sound in the left speaker.
The pinout is a standard, and in this case, suprisingly one that Amstrad actually stuck to: https://i.pinimg.com/originals/4b/58/9f/4b589f6f2a795390476033df660f95b0.png

The original 3.5mm sockets are not the greatest quality. If you are panel mounting, get a cliff electronics one, they are super sturdy.

Eh, the original Amstrad socket is a design that Cliff Electronics sell too :D Part No. FC68131.

Yeh, I did think that. I had in mind the chunky bodied bridge contact sort.
The following is pcb mount only but they do panel mount (mono only from what I see!)
