Here's my setting. I'm using S/PDIF Digital out from AX8 into the Focusrite Box.
The typical "issue" is the Clock Source / Rate setting which has to be 48KHz and S/PDIF for AX8.
If you set this and then notice that it changes back to 44.1 - that normally means that your DAW is also set to 44.1 KHz. I Logic Pro, this is set in the recording project settings.
Start off with your DAW turned off - so that you only have AX8 sending signal to monitoring (Headphones or Speakers).
The above settings work for me i.e. guitar to AX8 to Focusrite via S/PDIF to Speakers or Headphones.
You say that you can see the meters move - I'm assuming that this "movement" is reflecting what you are playing and not some random "hash" that is registering on the display?
You could try recreating the "Output Routing" within the Focusrite Control application? Choose one the of templates from "File: Output Presets" menu option. The one that I was using is called "Digital".
Your Focusrite will have multiple channels - mine has 4. My AX8 appears on S/PDIF 1-2 within Focusrite - see how S/PDIF is stated on the Right Hand side of my screenshot under "Hardware Inputs". You can add / delete here - click on the "X" to delete and then on the "+" to add. When you add, you can select the S/PDIF channel number e.g. S/PDIF 1-2 for a stereo pair.
Once you get audio monitoring working without the DAW - you can move onto the DAW settings.
So for Logic - Project Recording settings need to be 48KHz
You also need to select the Input Source for the "Channel Strip". I'm not very competent with Logic Pro but here's what I've found - the Channel has to be set to Input Source "5-6" in order to get Audio through from the Focusrite....not sure why and I'm sure that it has changed over the time that I have been using it - pretty certain I was able to set Channel Source to "1-2" at some stage. Experiment with different Input Channel Sources.
Finally, once you get Audio through to your DAW - don't forget that you can choose what your Focusrite is sending out to the Monitors / Headphones. You do this in the Focusrite Control app, within the "Outputs" section (Left Hand Side of application). If you select Playback / DAW - this will take output from the DAW (quite often you'll have noticeable latency if you do this) - You can leave set to "Hardware Input" but if you need to "track" i.e. record a track whilst playing another track in DAW, you can set this to "Custom Mix" which gives you DAW plus AX8 at same time with no latency on the guitar.
Some other thoughts.
1. Reboot the Focusrite - I use mine with Apple iMac and have noticed that sometimes things "lock up" - everything looks right / meters move but no audio path through to DAW.
2. Check that the Focusrite Unit is listed and selected within the "Sound" settings within your O.S AND the DAW application as opposed to the default / built-in computer sound card option.
Hope that helps.
