Here it is :

Code: Select all

hadrien@Ava-ordinateur:~$ ls -la /etc/udev/rules.d/
total 8
drwxr-xr-x 2 root root 4096 avril 20  2018 .
drwxr-xr-x 4 root root 4096 mai   25 11:10 ..

Dayyyum! Nothing helpful there. How about ls -la /etc/udev and cat /etc/udev/udev.conf

[hadrien38]

Yeah, here is the result for those :

Code: Select all

hadrien@Ava-ordinateur:~$ ls -la /etc/udev
total 28
drwxr-xr-x   4 root root  4096 mai   25 11:10 .

hadrien@Ava-ordinateur:~$ cat /etc/udev/udev.conf
# see udev.conf(5) for details

Maybe we're getting close. What's the output of ls -l /etc/udev/hwdb.d. If there's only one file in there, use cat to get it's content as well.

Arf, unfortunately, nothing here :

Code: Select all

hadrien@Ava-ordinateur:~$ ls -l /etc/udev/hwdb.d

This is nuts. We've looked everywhere that I can think of to find where the card might be blacklisted.

Actually, one exception to that, but it's not an area I'm skilled at. There might be something relating to your video cards. Your built-in audio card might also have HDMI options, and you have 3 other HDMI cards capable of audio. Maybe there's a setting somewhere in the Video/graphics options that has blacklisted the card you want working, but I have no idea where to look.

One place to look is /var/log/apt/history.log (or the .gz files that follow) to see what update might have caused this. Hopefully you'll be able to figure out the date the updates borked your sound, and can find the list of updates that occurred that day. That should help us figure out how to solve this.
