[SOLVED] Pulseaudio speaker-test. HDMI sound not working

[anmime]

Hello, I need help to make work PulseAudio sound in a TV Screen through HDMI connection.
Please, anyone could help with this?. I already can't figure whats happening and I shall no surrender. I dont want to be forced to run my non favourite SO to get this working properly ...


Context:
- It worked fine untill unknown fact happened. I suspect saving new xorg.conf file saved through nvidia-settings app as root mess something. but really I don't know why...
- No physical damage. (ports, cable, etc). I tried it on Windows and it works fine.
- Strange fact: screen/xorg/nvidia-settings detect screen on HDMI-1 port but pulseaudio detect the device connected on HDMI-3. It was in that way even when it worked properly.
- pavucontrol peakometers detect signal on output when I have this device setted as default
- speaker-test runs but device do not emit sound!
- Checked and tried everything I found on multiple forums, but nothing works
- I also tried to reconfigure and reinstall pulseaudio
- Internal Analog works fine
- Debian 10
- KDE Plasma desktop
- Nvidia 1050

I tried force loading new sink with no success, still no sound on HDMI through this sink

Code: Select all

pactl load-module module-alsa-sink device=hw:1,7

I also discard permission issues:

Code: Select all

sudo usermod -a -G audio,pulse,pulse-access,video,voice $USER
sudo adduser $USER audio

Another try reproducing sound straight to device with no success

Code: Select all

aplay -D plughw:1,7 /hd1/Descargas/prueba.wav

Code: Select all

Playing WAVE '/hd1/Descargas/prueba.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

I'm guessing that is something with logical addressing of devices, but really don't kwow well how to check and fix that

Cheers && Thank you!

I'm not familiar with speaker-test but I do a lot of audio work and tweaking so had a look at it. From the man page it appears you may be setting the -D parameter incorrectly, it should be based on the name shown from aplay -L (note capital letter L). Read man speaker-test.
And maybe you need to check the PulseAudio device rather than the ALSA device? Just guessing there.
In KDE there is a much easier GUI way to check if audio is working - System Settings > Audio > Advanced. Just select the desired output and click the buttons.

xorg.conf is usually not required these days. As you said it stopped working, maybe it will start working if you remove it. What purpose do you think it may serve?

Enternal gratitude sunrat! You was absolutly right about /etc/X11/xorg.conf. I just renamed the file (I prefer rename as .back instead of removing if bigger mess happens), reboot, and then got sound working again! I didn't try this solution, who may seem obvious , beacause I was pretty sure It was a required file who already exists before the edition.

I still din't undestand backgrounds os this case, multimedia services are far away from my knowledge area so I got lost easily. This is just a reminder... Never give up, keep pushing! Thank You!

You're welcome!
I don't think anyone understands multimedia services completely. I still learn new things regularly, some of which astound or amaze me. But xorg.conf has not been required for years except in occasional special circumstances, as Xorg is configured dynamically during boot sequence.

When I backuped xorg.conf I could see another backup from 2017. I`m pretty sure that I was twerking with powermizer therefore, cause Nvidia settings on multimonitor was always stucked at max consumtion, and still though system relays on this. Nowdsays I soppose all of this is integrated on Wayland, I need to check that, also take my time and update knowldege.

You said you're using KDE Plasma. Wayland is still under heavy development for Plasma and won't be ready for at least a couple of versions, maybe 5.22. Bullseye has 5.20. It can be run experimentally but I've heard less than favourable reports about that so far.
Apparently it works OK in Gnome but then you have to put up with Gnome.
