Ok, as long as my sound "onboard" I disabled it, rebooted and enabled it again.
So now I got in /sys/devices/pci0000:00/0000:00:1b.0/label only:
Realtek High Definition Audio Device
Where is my Intel HDA ?
lspci:
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High
Definition Audio
Controller (rev 05)
Thanks.
