Hi
can I make a x.x-soundcard to be X independants mono channels,
ex on 7.1 sound card? so mono line in to X-ch mono line out?
(on a windows10) ( and no reciver help)

problem:
case1:
I have a 5.1 or 7.1 ch sound card (sound blaster external USB)
I want to take a line in signal (mono) to be bridged so the output is 5,6,7 or 7 channel mono.

Case 2:
I have a 5.1 or 7.1 ch sound card (sound blaster external USB)
I want to play Spotify on that PC and the out signal is bridged so the output is 5,6,7 or 7 channel mono.

the dream senario is :
find a setting that always play out the signal to all the channels.

What the "hell im doing" this for:
I have a DSP-software that simulate a soundcard for 7.1 signals.
and acts like a bridge to the real soundcard.
so that signal goes instead of the normal:
"Spotify 2ch" -- "soundblasterDriver 2ch on the 5.1board" -- "line out 2ch out on the 5.1ch."

The software i have take this route:
"Spotify 2ch" -- "DSPsoftware that fix the signal" -- "soundblasterDriver 2ch on the 5.1board" -- "line out 2ch out on the 5.1ch."

the dream scenario for me is:
"Spotify 2ch" -- "SOFTWARE THAT 'MIX' 2CH TO 6CH" -- "DSPsoftware that fix the signal" -- "soundblasterDriver 2ch on the 5.1board" -- "line out 2ch out on the 5.1ch."

please, do someone any ideas?
:)
