Pulseaudio two outputs in one profile don't work proper

i want to output the sound on HDMI and DP. To archiev this, i searched how to do it and found this: https://unix.stackexchange.com/questions/401492/how-to-output-unique-audio-to-multiple-ports-profiles-of-a-pulseaudio-card I followed the answer from @dirkt and created a new profile in /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf.

[Profile output:hdmi-stereo+output:hdmi-stereo-extra1]
description = Both
output-mappings = hdmi-stereo hdmi-stereo-extra1
input-mappings =

I verified this is working with the gui pavucontrol and it seems working. I had a new profile called Both under the Configuration Tab and under Output Devices i can see both (HDMI and DP). But if i play music the sound will be played on the monitor which is connected via DP. No sound on the monitor via HDMI. Attached a image from pavucontrol (yea i know no screenshot, it's a kiosk system ^^). Do i miss something ? Thanks in advance!
