[SOLVED] Audio via HDMI does not work. Sink SUSPENDED - Intel NUC

Hi everyone,
i'm addressing a problem with audio via HDMI on an Intel NUC.

My setup is:
- Intel NUC (5.5.13-arch1-1) connected to a TV Monitor via HDMI
- TV Monitor connected to external speakers

The first occurence of the problem there was with an outdated installation, so i thought that it can be the problem. But the problem persists also with the upgraded system.

Overnight audio did not work. I discovered the problem using Kodi, indeed there were not the usual system sounds.
Then i tested with VLC: same problem.
But i noted the weird-beahviour with Youtube: in this case the video doesn't start, but it stucks.

Investigating the problem i tried the classic solutions:
- upgrade the system
- re-installation of pulseaudio and alsa
but nothing.

Furthermore, during this investigation i noticed that if i kill pulseaudio, the YT video starts (obviously without audio). 

Before of this post, sometime with multiple reboots, randomly, the problem disappeared.

Following there are some useful informations (i hope)

Thanks in advance.

Re: [SOLVED] Audio via HDMI does not work. Sink SUSPENDED - Intel NUC

Hi guys,

i solved the problem.
As i said, randomly the audio works.
Once the audio worked, i re-checked all the command and the differences between the outputs.

On the startup, the

pacmd list-sinks

command returns

$ pacmd list-sinks
1 sink(s) available.
  * index: 2
	name: <alsa_output.pci-0000_00_03.0.hdmi-stereo>
	driver: <module-alsa-card.c>
	flags: HARDWARE DECIBEL_VOLUME LATENCY DYNAMIC_LATENCY
	state: IDLE
	......

but if i start a YT video, it works well and the above command returns

$ pacmd list-sinks
1 sink(s) available.
  * index: 2
	name: <alsa_output.pci-0000_00_03.0.hdmi-stereo>
	driver: <module-alsa-card.c>
	flags: HARDWARE DECIBEL_VOLUME LATENCY DYNAMIC_LATENCY
	state: RUNNING
        ......

while in a not-working status, the 'state' was 'SUSPENDED'. (as we can see in the first post)

So i dig deeper in this way and i find this thread on unix.stackexchange: https://unix.stackexchange.com/question … -suspended

It seems that the problem is 'module-suspend-on-idle'.
I disabled this module editing 

/etc/pulse/default.pa

.
More precisely commenting this line

### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle

so

### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle

After that we have to restart pulseaudio and the problem disappears!
