SUMMARY
There is a problem with volume control in KDE Connect.
Volume up, volume down and mute commands are not working anymore.
Shutdown, suspend, turn off and on screen commands are working correctly. 
Kmix is not working.

I read article - https://forum.kde.org/viewtopic.php?f=19&t=166094
and I have noticed that I have not installed kmix. This is weird.
I installed it but it did not work. 

I used this command to check it:qdbus org.kde.kglobalaccel /component/kmix org.kde.kglobalaccel.Component.isActive
This command above did not return true. It returns this:
Could not connect to D-Bus server: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

I created another user. I have still this problem with volume in kde connect commands.
I have another system on my disk and this is MX Linux KDE 19.3. These commands work on it. And there is no kmix installed on system.
MX Linux has an older version of Kde Plasma 5.14.5. Maybe there is a problem with Plasma 5.20.4 on TW? 

STEPS TO REPRODUCE
1. Kde Connect is on
2. Volume commands are not working. These are commands that using kmix.
3. Other commands are working.

OBSERVED RESULT
Volume commands are not working.

EXPECTED RESULT
Volume commands are working such as increase, decrease volume and mute.

I suppose that it stopped working after update to Plasma 5.20.

It was an update of KDE Connect app in Playstore, ver. 1.16.0.
And now it works again!
All sound commands are working again.

Problem solved.
I hope so it will never appear again
