is there any way to split or define the input sources as seperate devices?
in audacity, i can record only the first 2 channels
i cannot record all (6) channels (it only records the first 2 channels and other channels seems silence)
in audacity (or any other program) i can not select second or third input device(s)
i need to select any recording channel, It looks like there are input volume controls ("cvolume") but no input switching controls ("cswitch") on that device
Code: Select all
