OK so on windows my soundblaster x4 can output both the spdif digital output thing and the analog audio to my headphones at the same time and use the volume knob to adjust the volume of them so one gets louder the other quieter.
on endevour os nothing of the sort exists, apparently this is the way to add a profile for it. however this didn’t work for me. ive also tried adding it to the 9999-custom.config but that didn’t work either. any assistance?
In that case just use qpwgraph and wire the outputs to both the stereo and s/pdif outputs.
If either of the outputs is not available then the driver doesn’t support them, which is not uncommon for Creative devices, to put it mildly.
