Ubuntu: Realtek ALC256: no soundcards found



Question:

I had a problem with sound, so tried to fix it according to answers already here. None of them worked for me and actually made it even worse!

I deleted pulse setting as recommended in one of the answers here

$ rm -rf ~/.conf/pulse  

I'm using Ubuntu 16.04, when I run

$ aplay -l  aplay: device_list:268: no soundcards found...  

Sounds settings show "Dummy output"

I tried to reinstall alsa-base, pulseaudio but it didn't help.

$ alsamixer  cannot open mixer: No such file or directory  $ pulseaudio -D  E: [pulseaudio] main.c: Daemon startup failed.  

EDIT: Now even Windows on the same machine doesn't recognize the device, so there might be a problem with device but I don't think so.
