Route Multiplicity audio output from secondary to headphones on primary

Hi to all,

I'm using multiplicity to transfer sound from my laptop to my desktop computer on which several audio output devices are installed. However, multiplicity always sends the sound from the secondary to the speakers (which are configurted as the default audio output) on my primary instead of the headset connected to it. Is there a way to route the multiplicity audio output to the headset instead and keeping my default audio device on the primary to be the default speakers? Any help appreciated.

Best regards
