Question Im having some audio issues

[Kr3xu]

Ok im using a splitter for my headset on my pc and it only detects my input(inbuilt mic) only when i unplug my output(speakers on headset) same thing switched around. I have searched far and wide on how to solve this and there is basically no result so this is my last string of hope.

ok when i plug both in only the headphones work but when unplug the headphones thats when it wants to detect the mic i think its detecting both the mic and speakers as a output but idk how to fix that
