Can't change in-call volume for headphones

[bjrnlndstrm]

Hello,

having some regular headphones (no buttons, bluetooths, or whatever) connected to my Galaxy S4 Mini Duos.

If I try to take calls this way it seems I can listen in my headphones and speak into the mic, which is all good. However, the headphone volume is painfully loud, and is not affected by the volume buttons. The volume buttons shows the call volume slider and moves it, but doesn't affect the headphone volume at all. Neither does the media or any other volume slider seem to affect the volume from the headphones during calls.

Any clues?

Same issue with my 9195. However, Samsung support seems to refuse assistance. They suggest I should get a new headset. I don't think they are really looking into it.
