Different Audio Outs for Movies and Music

[hp1975]

Is this what I’d have to do? It seems like it’s the same type of effect the OP is looking for?

Is it possible to have used DAC output and hdmi audio output simultaneously?

I have a USB dac that works perfectly with osmc. I have it running out to my hifi and use it for airplaying Spotify. Most of the time I use the tv output for sound, and would ideally just mute the tv and turn on the hifi to get the sound from the speakers. Currently I have to go into settings and turn on the dac, which cuts hdmi sound output. Is it possible to have dual output (like we used to with analogue and hdmi)?
