The live CDs are very out of date. Do a network or server install and install TDE
afterwards. I personally do a fresh debian and install the TDE base, pulseaudio, flatpak,
network-manager, network-manager-tde, pavucontrol (I switch audio outputs between speakers
and USB dac often) , tdesudo, and libreoffice and this gets me a good setup. The only
thing I do after is change the trackpad config as per debians website to enable tap to
click.
