Optiplex 390MT: Mic not working when plugged into front panel's 3.5 mm outlet.
I have Optiplex 390MT and can not get mic working when plugged into the front or rear 3.5mm outlet.
I am trying to use my regular wired 3.5mm cell phone headphones (mic+speaker) as a microphone for my desktop. What I do I plug the 3.5mm jack into front panel's outlet (and rear panel too) for microphone. The heaphones get recognized, however they do not capture any incoming sound.
Am I missing drivers or there is some config that need be done?
currently it says I am using Conexant HD Audio driver.
I found similar discussion here:
https://www.dell.com/community/Desktops-General-Read-Only/head-phones-not-working-when-plugged-into-front-panel-head-phone/td-p/5092990
however this does not apply to me since I do not have anything else plugged into my audio inputs/outputs in rear or front.
Thanks,

390 front panel has separate 3.5 mm microphone and headphone connector ports. see pg.3

your combo plugged in headphone jack will only work as headphone but not microphone at same time. there are USB type headphone/mic combo that may work provided appropriate driver is installed.

as far as I know the 3.5 microphone jack is only for input and headphone jack is only for output. if you plug a combo jack into either port, you only get what the jack is supposed to do, which is one thing only.

@redxps630 ,
Yes I am when I plug my combo headphones into 3.5mm mic jack I expect headphones to work as mic only.
Is that a reasonable expectation?
For some reason it is not what I see in my case; hence original question.

Thank you very much! while I currently do not have that splitter I am 99.999% sure now that is the exact problem.
Thanks a ton for pointing me to the right direction!!
