On some mobile phones no voice on (Youtube) final mix

[Theo van 't Hert]

Hi,

After many a years making my songs with Native Instruments on Cakewalk by Bandlab, on some mobile phones
the owners hear everything but no the voice on my (Youtube) final mix.

How on is this possible?

Sinecerely,

Try Inverting the phase of one of the stereo channels of your voice track.

Thamk you very much for your response. The problem I have is that I can't integrate Kontakt optimal in Cakewalk.
