Desktop doesn't react to 3.5mm headphone buttons

[Yorimirus]

Hello, I have wired headphones that I often connect to my PC. Sony MDR-EX155AP. These headphones have a button to pause/unpause whatever video/music is currently playing. The button works when I connect them to my phone or when I’m on windows, however KDE Plasma does not seem to react when I press the button.

It seems like KDE Plasma does support this because on my wireless headphones this works just fine. I assume it has something to do with the 3.5mm port? Any ideas on what might be the problem?

Does this behaviour occur for various applications or when playing via a browser only?

Reads similar to this ‘Plasma 5’ issue (perhaps never fixed)…

Anyway, have a read of it and see if any of it applies/helps. In the end you may need to report it.

Seems to happen everywhere. Wireless headphones work like they should while on the wired ones KDE plasma does not detect the button clicks at all.

This headphone is for smartphones (see the manual):

The smartphone needs to be CTIA standard compliant (see the Sony compatibility page):

Your computer audio socket most likely uses another standard and you need an adapter. This is backed by the statement on the compatibility site:

So find out what audio socket is built in your computer and which type and standard it is.

Official lenovo website (my laptop is lenovo ideapad 5 pro 14ARH7) only says “headphone / microphone combo jack (3.5mm)”. I have no way of verifying what standard it uses and it’s just a minor inconvenience so I guess I won’t bother. Thanks for explaining.

I assumed that your mention of it working in Windows pertained to the same machine.
