ok...yes W10 options.. but all is as i said. it is configured correctly, in 'test' i hear all speakers!
in music, or web sites with sound i hear sounds from necessary speakers.
but in GPL.. only left and right speakers.
i just read elsewhere on SRMZ that suggested 8 be the number of sounds in GPL
i thought (long ago) it was to have 4... i believe that is where i am....so i will try 8 and see if that makes any change
