Up until yesterday, i would have normal sounds from my
speakers. Yesterday PM, i found that i no longer had
sound. I rebooted, checked my speakers, swapped them
with another pair, etc.
My pc is designed with speaker jacks in both front and
back, which is where i normally keep the jack. However,
when i moved the jack to the front, my sounds resumed.

The back panel jack has probably become damaged.

The type of jack that are typically used on PCs for sound-related
connections are well-known to be relatively fragile.

If it is is any consolation, the PC I'm typing on right now has a damaged
front-panel jack, and I had to move my headphones to the rear-panel jack.

The front-panel jack is relatively easy to repair, but I'm either lazy or
kinda booked-up at the moment.

So what would the issue in the back be and from what?

Most probable answer in my experience - a damaged jack. I'm intimately
familiar with the wiring that relates to both jacks, and detailed knowlege
of it can explain everything that you have experienced.

Necessary steps to resolve are?

Actually fixing that back panel jack is non-trivial. It is more than likely
soldered to the motherboard, which is a multilayer circuit card. So, you
need to remove the motherboard, obtain the necesary tools and experience
required to replace the jack, and then properly execute a slightly risky
series of technical operations.

Or, you can just continue to use the front-panel jack. Or, you can modify
the internal wiring of the PC to add a second back-panel jack of the kind
that is broken.
