HDMI: audio problem in Intel NUC6i7

Zapata · 2017-01-08 10:16:04

Problem:
No sound through the HDMI.

Description:
I can get sound through my headphones (the analog output) using pactl set-card-profile 0 output:analog-stereo, but when I tray to configure the hdmi interface to use TV speakers using pactl set-card-profile 0 output:hdmi-surround, while the TV is on I get no sound.

What I have tried:
- I have tried all card-profiles using pactl set-card-profile 0. Only works for my headphones with the profile "output:analog-stereo" ... and ... works with the profile "output:hdmi-surround" (this only works without initilize X server). I can't figure out the problem.
- If I startx the X server (I use awesome wm) turn off/on and disconect/conect hdmi cable doesnt works, But if I wait until NUC turn off screen and the TV's energy system turn the TV off; then I turn on back the TV and set by pactl the HDM, it works.
- Unmute all channels using amixer sset "Channel" unmute and using alsamixer (unmuting with key M)
- I have tried aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav with all devices from the output of aplay -l. I got no error in any but I only get sound through my headphones with the analog ouput (card 0 device 0)
- I disabled ~/.asoundrc by renaming it to ~/.asoundrcBack
- I have turn off/on TV(hdmi) without disconect the hdmi cable.
- I have just change the input source of the TV, lest say from HDM1(where NUC is conected) to TV(regular TV) the back to HDMI1
- I have tried a different HDMI cable

I would like to find a solution.
Any suggestion?

My system state is:
- I have an Intel NUC6i7:ArchLinux kernel 4.8.13-1-ARCH x86_64 GNU/Linux.
- It is working with ALSA and PulseAudio. I use awesome wm instead of a desktop enviroment.
- Some system info command outputs are:
