h61 I set up a computer for my parents with elementary os. I installed an Asus P8H61-I motherboard which contains an integrated Realtek ALC887 sound card.

The system doesn't recognize the sound card. Here are the results of some commands:

lspci | grep audio

doesn't return anything,

alsa force-reload

return

Unloading ALSA sound driver modules: (none loaded). Loading ALSA sound driver modules: (none to reload).

aplay -l 

no soundcard detected

and

cat /proc/asound/cards

let me know that asound doesn't exist.

I tried installing Realtek drivers but nothing happened.

Here is a log from alsa : Log

Can someone help me? Thanks.
