Updated update Apparently it is still necessary (21.3)
Update: this is no longer necessary in Mint 20.02
I like having my volume control in the bottom right corner of the screen so I can quickly and easily throw the mouse to the corner and scroll for volume control. I also like using multiple screens, each with their own panel. Unfortunately, Cinnamon only allows one instance of the volume control applet.
In the past I’ve used the “Volume control 150%” applet for my second screen, but this runs into a problem with Firefox whereby the volume suddenly jumps to 100%.
To run multiple Cinnamon volume controls:
sudo cp -r /usr/share/cinnamon/applets/sound@cinnamon.org /usr/share/cinnamon/applets/sound2@cinnamon.org
sudo nano /usr/share/cinnamon/applets/sound2@cinnamon.org/metadata.json
Change the UUID from sound@cinnamon.org to sound2.cinnamon.org and change the name to Sound2
You can now add the “Sound2” applet to the your other Cinnamon panel. Or the same one. Add more. Go nuts.
Thanks for tips!
The command isn’t with “sound2” word ? :
sudo cp -r /usr/share/cinnamon/applets/sound@cinnamon.org /usr/share/cinnamon/applets/sound2@cinnamon.org

Even more useful tip from this user, although in Mint 20.2 you can add multiple instances of the sound applet by default.
What do you mean by “Update: this is no longer necessary in Mint 20.02”?
On Mint 21.3 I cannot add two Sound applets natively. Did they enable you to do so in 20.02 but then rolled back on that?
Looks like it.
