1, 6, 7 and 8 all appear to be grounds.

The sound probably comes from either 2/3 or 4/5, and you can tell by
touching a headphone tip (with the "ring" grounded) to those points.

The other points are likely where you jumper to send sound to the
speakers (e.g. likely 2 to 4 and 3 to 5).  even if it's wrong, a
momentary test is unlikely to do any damage.

Does anyone know what solder points to connect in order to get the
speakers to work on the computer. Or does anyone know where to get a
replacement jack?

Thanks!

OK. Thanks. I will wait and see if anyone else has an opinion on it
and then start shorting things out to see what works.

#4 looks like it has a trace heading towards where the speakers are.
I agree on the grounds being 1 6 7 8

Would a multi meter help determine which ones go towards the speakers?- Hide quoted text -

#3 appears to be a dead end trace, I turned the motherboard over and
there is no trace leading away from it on either side of the board.

So that leaves us with 2, 4, and 5 with traces leading away from them.
#4 has trace leading away on both sides of the board.

Hope this helps.
