VNC & local sound problem

Hello,

I know that VNC supports audio only on paid version, however this is not such case - I want to play sound from RasPi 3.5mm output.

 I use VNC with Raspberry Pi 4B which has low resolution (640x480) touchscreen attached to HDMI output. When I connect with VNC client and run speaker-test, I can hear sound from speakers connected to RasPi 3.5mm jack. Now, when I created virtual desktop with more user friendly resolution and connect with VNC, then I cannot get any sound. Right click onspeaker icon (top right screen corner) says "No audio devices found" while on low resolution connection I see both Jack and HDMI.

Is there a way I can play sound on 3.5mm jack using virtual desktop?

Thank you,

J.
