Combine HDMI+PULSE audio outputs

Hi all. I'm currently testing LE11 on amr7 rk3228, I'm trying to combine HDMI and Pulseaudio audio outputs at the same time. The idea is to have Pulseaudio on the lan network, while playing on HDMI. I'm trying to create a combined sink while Kodi is set to Pulseaudio as Default, but it didn't work. I also tried default HDMI in Kodi, but I couldn't read it from Pulse. Has anyone tried this? Can I achieve this by creating a .conf in /storage/.config/pulse-daemon.conf.d ? I also haven't been able to get my default.pa file in /storage/.config/pulse to be read. I can't find any options anymore since kodi is hogging the outputs. SNAPCAST is not a viable option, the latency is unpleasant. I appreciate your help.
