Play simultaneous sounds on Pi via Xojo

I am trying to simulate an elevator as an art installation. As the sound function in XoJo doesn’t seem to work, is there a way to play two different sound files at the same time on the Pi4 via Xojo? For example, elevator music with sound effects overlaid. Thanks for any help.

Do i have been pulling my hair and it must be an issue with the rpi4. It works just fine on the RPI3. I have a feeling that something is hardcoded with the sound ports and since the pi4 has two via hdmi and one headphone (+ gpio options) something is just off. Sound works from the HDMI ports so a hdmi sound splitter will do the work but the is bug.
