No sound and other issues

[MohsenGamer11]

There is no sound its disabled Idk how to fix it. In the log in screen I couldn't press the enter key then I later found out that the script didn't install kde plasma there was no desktop enviromment only a window Manger that explains why entering password wasn't doing anything and I had to install kde and then also the application cause these packages weren't installed and the last thing there is not network manager I tried to enable the service but network manager doesn't exist please fix these issues I really like this script but there are imperfections in this script
