This question already has an answer here:
I bought a Dell Inspiron N4110, the sound plays fine from the speaker, but when I plug my earphone (which has the 4-segment TRRS jack, i.e. stereo+mic) then human speech gets distorted although background music tends to play fine this causes speech to get drowned in the music (in movies this means I can't hear what they were talking despite my ear getting hurt by the loud background music).
I tried multiple different video, they're all exhibiting the same symptom, the earphone somehow can distinguish human voice and background music and filter out only those human voices in all the videos I tried.
I tried using a different earphone (a 3-segment TRS jack, i.e. stereo), and this plays fine.
It wasn't the TRRS earphone either, as I regularly use it with my mobile phone fine.
So my guess is that the distortion is because I'm plugging TRRS jack into a TRS socket and they doesn't work well together.
The question is:
- is there any workaround to use a TRRS earphone on a TRS socket without distortion (I don't need to use the mic)?
- (bonus) why is it distorting only on human voices?
