I have an old laptop (Thinkpad T61p [1]) with a stereo and
microphone jack, both 3.5mm.
How do one know if it is a TRS or TRRS variant without opening the
case ?
Maybe it is a trrs jack since when I inserts a trs cable (to speaker)
the ouput sound whines a lot, mostly masking the intended sound.
I found some specs in [2] and [3].
