As I said, in Submix Mode, every HW output is a submix of its own. So your recording interface has so many submixes as it has HW Outputs (Analog, ADAT, .. )
If your speakers are connected to AN 1/2, then click in bottom row (HW Outputs) to channel AN 1/2, then decide which HW inputs and SW playback channels (Top / Middle Row) you want to listen to, in those channels raise the faders.
Tip for speed: when doubleclicking a fader it toggles between 0dB and "off".
More generic / better way for 1st time setup
For 1st time use there is even a much better way to 1st reset TotalMix FX completely and then to change the routing to playback everything to "Main Out". Becaus by this all HW inputs and SW Playback channels are then properly setup "in one sweep" to playback to your Main Output. I will show you the steps now:
1. you need to assign "Analog Output AN 1/2" to "Main Out", see 1st picture below.
2. then you need to reset totalmix and then choose the proper function to playback everything to Main out, see 2nd picture below
3. The result of this you store as Snapshot 1.
- Open the Snapshot Menue on the middle right of Totalmix, if not yet done
- Press "store" button and select Snapshot 1
- You can rename the Snapshot to "Main Out" as synonym, that a click to this Snapshot 1 button routes all to "Main Out"
4. Do not forget to save these settings, by saving Snapshot and Workspace settings
- File -> Save Snapshot As
- File -> Save Workspace As
5. You should save this also to one of the 30 Workspace Quick Select Slots, so that you can recall a complete Workspace Settings (with all of its snapshot and workplace settings) very quickly.
6. Under Options -> Preferences I recommend that you select this option
(x) Always init DSP devices with TotalMix FX settings
Then you do not get asked on Windows reboot, what settings you prefer, those on the device or those stored in TM FX on PC.
This is being explained here in detail:
I wrote a primer for TM setup in DE/EN: https://www.tonstudio-forum.de/blog/ind … rnal-equi/
There are also RME training videos available which are compact and well done and split in several chapters.
They do not take long: https://www.tonstudio-forum.de/blog/ind … al-Videos/
My primer also contains a Visio Drawing about routing which also helps to get better unterstanding about routing and the position of TM FX in Windows and I also explained the Mixer Block Diagram, that you find in every products manual.
