HDMI no sound

I have no sound over HDMI in my Xubuntu. (sound goes always from my laptop speakers)
I have checked some soultions already but none of them work for me.

This is my alsamixer settings: https://www.dropbox.com/s/6a5ab6splh...mixer.png?dl=0

All is unmuted and I guess S/PDIF is HDMI ?

This is output of aplay so I assume that HDMI is 0,1 but it still gives no sound.

Code:

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC663 Analog [ALC663 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 1: ALC663 Digital [ALC663 Digital]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
 
# aplay -D plughw:0,1 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

What else can I do ?

As I understand SPDIF is SPDIF and the HDMI is a seperate sound device. I thought the 'buntus used PulseAudio? Open the pulse mixer snd check.

If SPDIF is not HDMI then in my alsamixer has no HDMI.

Here is a screenshot of Pulse on the configuration tab.
If I choose any "Digital" option then no sound form laptop speakers... and also nothing comes from TV speakers:

Though in this case when I try aplay it says that "Device or resource busy"

Code:

# aplay -D plughw:0,1 /usr/share/sounds/alsa/Front_Center.wav
aplay: main:722: audio open error: Device or resource busy
