I installed the gnome desktop version of the solus system, and then I installed the budgie desktop according to the official help document.
I entered the budgie desktop, set it up according to my preferences, then exited the user, entered the gnome desktop, and then logged in. I entered the budgie and found that the sound was gone. I opened the settings, and the sound test window showed "null". I tried to log out. Go into the budgie desktop again, no! I can't get in. It shows an error.
I restarted and entered the budgie desktop. The problem was gone, but there was no sound when I logged in after logging out.
In addition, there is another problem about the Ibus input method. I installed the Chinese IME, but when I tried to enter it, I found that there was no candidate box.
I'm sorry, I didn't take a screenshot.
