No sound on TV via HDMI

[slawul]

I raised the subject of the telegram several times, I promised that I would write how things are going.
I needed to connect my laptop to the TV via HDMI - I use MATE as an environment, so I checked the connections:

Code: Select all

 sysctl /dev/sndstat
pcm0: <Realtek ALC269 (Analog 2.0 + HP/2.0)> (play/rec) default
pcm1: <Realtek ALC269 (Internal Analog Mic)> (rec)
pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> (play)
No devices installed from userspace. 

I changed the output setting:

Code: Select all

 sysctl hw.snd.default_unit = 2
hw.snd.default_unit: 0 -> 2 

Now there should be sound on the TV:

Code: Select all

 sysctl /dev/sndstat
pcm0: <Realtek ALC269 (Analog 2.0 + HP/2.0)> (play/rec)
pcm1: <Realtek ALC269 (Internal Analog Mic)> (rec)
pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> (play) default
No devices installed from userspace. 

Unfortunately, the Sound Preferences did not change anything either.
What is it like in GhostBSD-XFCE? I downloaded and recorded it on a pendrive, pulseaudio as a sound server no pavucontrol and xfce4-pulseaudio-plugin - how to control the sound?
After some problems I was able to install everything I needed on live - the result is the same as on GhostBSD-MATE, the picture on TV via HDMI is sound, no sound only through the laptop speakers.
Here are some photos taken with the phone.

Knowing my previous experience, I decided to check what it looks like on Manjaro Linux.

What's the problem on GhostBSD that sound doesn't work via HDMI on TV, and on Manjaro Linux you can even select the HDMI channel?
