Front right speaker now sounds like the subwoofer... [Logitech Z506]

And no idea why. Working fine, stick on some music list on YouTube for a few hours, got back to the PC and thought it sounded a bit odd. Did a speaker test via Realtek HD Audio thing and when it selects the front right speaker the sound comes out the subwoofer. The subwoofer tests sounds identical to the FR speaker test. Also the same issue through Windows speaker test.

Just downloaded the latest Realtek drivers and no joy. I can't even rejiggle the jacks as the front right speaker is a unique port (as it carries power too I imagine).

I imagine if the actual speaker had gone FUBAR then the sound test would just be silent? Rather than playing sounds through the subwoofer?

Thoughts? Suggestions? Google didn't help

This must be a hardware thing.
So I switched the front and rear cables around, and did another sound test. Sure enough the front left and front right sound came from the rear left and right as expected. The rear sound test did as described above - sound out the front left, then sound out the subwoofer.

So it can't really be an onboard sound issue where it's directing front right sounds to the sub, otherwise the rear right would have come out the sub with reversed cables, right? (Confusing myself)

Also I can't individually switch the front right jack somewhere else as it's a VGA type connector (obviously it isn't but it has the power button and volume knob so guess the usual jack wouldn't suffice).

Submitted a warranty claim with Logitech, just dunno how that will pan out.
Another random thought was that the speaker unit knows the front right speaker is nackered, so is pumping that audio through to the sub to get some sort of output? Maybe?

Aaaaaand just plugged headphones into the headphone jack on the front right speaker, got fine audio in the right earphone.

Thanks for the resources. No idea how you found that on TG, I couldn't get anything to match!
Going to get my old speaker system and mix and match it all to get it going (failing any luck with Logitech warranty)

I'll certainly give that a go if out of warranty. Nothing to lose at that point, but I haven't held a soldering iron since primary school.
For now I've switched the front and rear jacks and re-positioned the speakers, so now I don't have a rear right. More workable than absence of front right I guess, but it will annoy me when I fire up the FPSs again...
