Lumia 950 mono or P2 with problem?

My Lumia 950 works only in MONO when using earphones in the P2. Testes a lot of earphones and apps.

Sorry... I'm a bit lost. What is the P2?

Analogic audio output, where you plug your headphone.

OK... I'm used to seeing just headphone jack or 3.5mm jack. I thought maybe it was a special adapter or widget thingamadoohickey.

If many types of headsets are failing to deliver stereo (and all audio settings are correct) it may be time to look at warranty.

I've not really used it so don't know if the 3.5mm jack is tested or how well.
