Dual audio out with x sim advice

[Cactuspenii]

I have an asus rog laptop im currently running my rig from. I run sound via hdmi to a bose lifestyle system and want to run separate audio to rhe buttkicker with xsim without actually needing a second sound card. Can i just use windows built in multi audio out support to do this through a headphone jack and still maintain the immersive 5.1 audio through hdmi? Please advise. Much appreciated in advance guys!
