Ok, cool. Notice that I wrote "do this for pin 0x18 only, not for pin
0x21", where as you replied "I'll do this for pin 0x21 only, not for pin
0x18".

0x18 is for input switching, 0x21 is for output switching. If you remove
jack detection, like you did, you will need to do this switching
manually, e g in pavucontrol or gnome sound settings. That is, when you
plug your headphone in, you need to manually select "Headphone" too, if
you don't, the result will probably be that you hear sound in both
headphones and speakers.

Anyway, let's guess that the high pitched sound, as well as the lack of
headset microphone input, is because your headset is OMTP and that the
Vaio only supports CTIA. That's my *guess*, but it could be wrong, and
it would be good to have this confirmed with a CTIA headset.
