No sound on Ubuntu 20.04 XFCE (ARM) VM

Running Ubuntu XFCE 20.04, the ARM version, does not have sound. Playing music with volume on, keeps silent. I must admit that it runs in a QEMU virtualization environment (UTM) on a Macbook Pro M1, so I thought is was the virtualization software, but a Windows 11 VM plays music flawlessly. I used wired headphones to test as I have no speakers or Bluetooth audio attached to the Macbook. These do work in native macOS and in a Windows 11 VM. I found this webpage with a similar problem (on a real computer, no VM) and tried these options to no avail.No sound on arm ubuntu 20.04aplay -l results in:

I tried all options of pavucontrol but it remained silent.

Is there any way to get sound in Ubuntu ?

I faced exact problem on my VM Ubuntu. After long unsuccessful search I discovered next simple solution:

1. Play any audio or video in Ubuntu;
2. While playing open your main OS;
3. Change level of volume in usual manner;
4. Return to your Ubuntu.
