How to use TRRS microphone with HD Audio?

I am trying to get a new microphone to work with a MSI X570-A PRO desktop PC. It uses a TRRS 3.5 mm connector, and seemingly pretends to be a headset, with the left/right speaker tip/ring connected...

I want to post new blogposts here, but I keep forgetting, so I'll post the latest batch now 😅

Smartphones without a headphone jack are dumb

Nothing Phone 3a Pro is good, but the absence of the 3.5mm jack keeps ruining my day.

So happy the #audiojack has not become obsolete yet. #nintendodirect 😀

Still disappointed that the new #fairphone5 doesn't have an #audioJack . Was there ever any discussion about it, #fairphone ? In your release you talk about users begging for #oled , but I heard a lot of people asking about the good old jack instead.

Could you reveal any numbers behind https://support.fairphone.com/hc/en-us/articles/9836188988049-Audio-Jack-3-5mm 's "user want thinner phones, not headphone jacks"?

"This is one of the Fairphone classics. Find a #headphone #jack, front and back camera lens action, a large screen for all your watching and scrolling needs, complete with a swift and easy to use software setup. And not to forget the Fairphone promise of a very very very long life." ;)

This 3.5mm Cable Distorts Signals, Hides Audio-Filtering Circuit

[Avian]'s dad got a new ham radio transceiver with a 3.5 mm jack, and his pile-of-cables got him a headphone cable from Bose headphones. He built a DB9 to 3.5 mm adapter with that one - and it failed to let data through, outputting distorted garbage of a waveform instead. With a function generator and an oscilloscope, [Avian] plotted the frequency response of the cable, which turned out to be quite far from a straight line. What was up?

Taking the connector apart was a tricky job. A combination of blunt force and a nail polish remover soak didn't quite get them all the way, so [Avian] continued to apply blunt force and took the jack apart with minimal casualties. Turned out that there was more to the 3.5 mm plug indeed -- a whole PCB with a few resistors and capacitors, reverse-engineered into the schematic seen above.

Looks like Bose decided to tweak the audio characteristics of a specific pair of headphones, and an in-plug filter was, somehow, the most efficient solution. We probably shouldn't expect to see this often, but it bears keeping in mind: next time your repurposed 3.5 mm cable doesn't behave as expected, it would be prudent to do a capacitance test with your trusty meter or oscilloscope.

With how small MCUs have gotten, you can easily hide more than just a few capacitors! We don't often see circuits built into cables, but when we do, it's for malicious purposes.
