Hi @crustypants,
I know this is a long time coming and maybe not relevant any more, but for future reference for anyone else coming across this:
https://github.com/x42/scarlett-mixer is for Scarlett Gen 1 devices
https://github.com/geoffreybennett/alsa-scarlett-gui is for everything else since then (Gen 2, Gen 3, Clarett USB, Clarett+, soon Gen 4 and Vocaster as well)
I tried to add support for Gen 1 previously, but didn't manage to. Without the hardware in front of me, it's pretty tricky and I gave up for a while.
Someone sent me an 18i6 Gen 1 which arrived today.
The Gen 1 driver doesn't seem to support reading the hardware state, so what you see in scarlett-mixer might or might not represent the actual state of the device.
Changing these settings should change what comes out of the first two outputs:

To check this, play some audio, change those to "Off" and the audio should go away. Change them back to PCM 1/2 and the audio should come back. If you still hear your inputs coming through your outputs that's Ardour, not the interface. But to rule that out: quit Ardour, do you still hear the inputs coming through the outputs? You can also check by unplugging just the USB cable from the interface. At least the 18i6 can do direct monitoring without the USB cable plugged in (surely the 6i6 can as well). You can confirm this by setting the Monitor controls to "Analogue 1" and giving it a go.
Hopefully with those ideas you can narrow down where the issue is.
Regards,
Geoffrey.
