Strange that the manual doesn’t indicate that the USB port, which is on the back panel with the “out” ports, is the necessary input. Directions were sadly lacking.
The only problem is I have the turn the volume way up on the Surface Pro and the QSC speaker.
I’m not sure it'll be loud enough for gigs.
My Solo is rather older, but I expect the operation would be similar.

If the level seems low, then I think there's still something not set right.
The large rotary control on the front panel should give good adjustment to set the volume and I suspect that's what's not yet set right. I think it control both the headphone volume and the output volume on the reap panel jacks, which may be fooling you.

My Solo manual says a maximum of +9dBu, where the normal line level is +4dBu, so you should have almost twice the voltage levels available than you need. I would expect the Surface to send sensible data. IIRC there's usually a mark on the Windows volume control dialog that shows the 'normal' volume setting.

You don't say what you have connected where, which would be helpful to help us spot any user errors. Perhaps you would indicate what you have connected where and to what the various switches and knobs are set.
