HDMI Sound Card no detected

Hello

I have a Dell XPS 15, with an hdmi output. with alsa, no pulseaudio.
I'm trying to use the hdmi to output video and audio, video works fine.
However i have no audio.

I tried checking different info and thread on this subject, especially the wiki, however, i see one main difference.
It looks like i have no hdmi sound card

[glow@dug ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3661 Analog [ALC3661 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

On windows, it works, so the hardware is here.
Any ideas ?

Re: HDMI Sound Card no detected

What is the make and model of your graphics card? And which drivers are in use? To answer both questions, try the following command:

lspci -k | grep -A3 HDMI

Example output from my machine, to help guide you on what to look for:

[jbs@dmb-gaming-laptop ~]$ lspci -k | grep -A3 HDMI
00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Trinity HDMI Audio Controller
        Subsystem: Hewlett-Packard Company Device 1849
        Kernel driver in use: snd_hda_intel
        Kernel modules: snd_hda_intel
[jbs@dmb-gaming-laptop ~]$ 

If you get no output back, you're HDMI is most likely isn't recognized by the system. Then we start troubleshooting drivers.

EDIT: There are also dell xps threads throughout this forum. See here: https://bbs.archlinux.org/viewtopic.php?id=205147
