configuring suspend and sound card on debian 10.9

Dear all,

I have installed debian 10.9 on thinkpad e15 and there are still few things to configure, there are no sound, it says dummy output, how can I configure the sound card ?

#lspci shows:

Quote:

Multimedia audio controller: Intel Corporation Device

Another problem is that the trackpoint mouse with its buttons does not work, I tried configuring it using the help of thinkwiki page, but I have no previous experience with it and thus was not successful, I use linux since a while a go but never encountered this issue!

Another important problem is that the suspend does not work properly, when running
#systemctl suspend

the system suspends correctly, but after resuming it and logging in, in few seconds the computer automatically reboots!?

Any help or hints are greatly appreciated !

Thanks in advance,
