Latte-dock not showing up and laptop sound buttons not working on startup

I recently did a fresh install of Manjaro on my laptop. I am using Plasma and the Git version of Latte-dock.
Every time I turn on the computer, Latte does not show up. If I hover the mouse over the region where Latte should appear and click the right button of the mouse, Latte’s menu shows up and I can change the Layout. When I do it, Latte shows up.
However, all sound buttons of the laptop (mute, volume up/down, and microphone mute) do not work. In order to make them work, I have to log out and log in again. Most of the times, doing so solves both problems, i.e., Latte shows up on the correct layout and the sound buttons do work;
but sometimes I have to repeat the procedure, that is, to log out and log in three or four times until everything works.
I tried to remove Latte and install the version existent in the Official Repositories, but the problem persists. I don’t know if the problem is related to Latte-dock or if there is something wrong with my installation (wrong order of starting up processes, for example) and the weird behaviour of Latte and the sound buttons are just consequence of it.
This is very annoying and inconvenient, because it takes much more time to start the laptop than it would take if everything was working fine.
Any clue on what might be causing these problems?

Here is some basic information about my system:

Basic info doesn’t help a lot… It’s better to just post the output of inxi -Fza

For example, your basic info doesn’t tell us what laptop you’re using, which could be useful to help with:

It might be important to know that my previous installation in this laptop was also Manjaro KDE with the GitHub version of Latte-dock (all kept updated), and I never saw this strange behaviour before. It only started after the recent fresh install of the distribution.

Media Keys that Do Not work out of the box:

You must find a workaround and bind the keys yourself for the rest of them.

xbindkeys and xbindkeys_config-gtk2AUR can be a solution for media keys that are not working. This solution also allows you to rebind the ThinkVantage button and certain FN layer shortcuts (the blue logos on the keyboard).

Thanks for your reply and suggestions, but that information is not accurate.
I can state that all sound buttons work out of the box in ThinkPad T420. I have this laptop for more than one year, always running Manjaro KDE, and everything has worked fine until I recently reinstalled Manjaro.
Moreover, they do work after I log out and log in, as explained in the first message, without the need of any workaround, provided I change the layout of Latte-dock first. The problem is of different nature.

The problem was automatically sorted out in the following version of Latte Dock.
However, for those who end up here, the problem may be related to the issue reported in this post.
And if that is the case, according to the developers, the issue is fixed in version 0.10.8.
