Sistem sound configuration

[E69_vencejo]

Hi all, and sorry for my english,
In my case, after install patch, the sim sound is in stereo mode, and i cant change/select from audio options.

Solution is change value in conf.ini archives. There are two, and i´m not sure, then i change the two inis (in steam and in documents).
Look for "speakers" (not Speakers). The inputs are:

auriculares= 0
stereo= 1
cuadrafonico= 2
envolvente= 3
perifonía de 6 canales= 4
cubo de 8 canales= 5
ambisónico= 6

I have 5.1 sistem, then i put speakers=3, and... to flight
