[SOLVED] debian 8 jessie no sound,no wireless connection, how to do it?

I have no idea about KDE, sorry.

Did you try running this command in KDE:

# nm-applet &

I think you should probably just use XFCE

Also, what does "find no settings" mean?

I appreciate that English is not your first language but if you continue to ignore my questions & suggestions there seems little point continuing this.

and i find in the system settings, Hardware--Audio and Video settings,only a Dummy output is active, and other Built-in Audio..., are inactive,in grey.
so i think
root@debian:~# lspci -v
this command only shows this system can find the audio hardware ,but need a drive to make it work? am i right?

find no settings.

i mean i could not find settings on howto make wireless work,under KDE. but cable connection work well, and also i do not know where the place i can setting the network.
the KDE desktop is much like the KDE in Opensuse.
but opensuse is much more beautiful than debian.

maybe when i installed the system not completely, some utility may not have installed. i will find it myself. i am grateful for your help.
