No audio from HDMI

[Member tizianomattei]

Hi, I’ve installed Antix-21 on my older Fujitsu laptop and it’s working great, except I can’t get the sound out of the HDMI interface.

It seems a similar problem to this one: https://www.antixforum.com/forums/topic/cant-switch-to-hdmi-audio-on-live-boot/

I’d rather not install pulseaudio to solve it, to keep the system as light as possible.
I’ve seen the “s/pdif” channel in alsamixer and toggled it on, but unfortunately that proved useless.

The “choose soundcard” script says there’s only one sound card, so it has nothing to do.

Any ideas?
Thank you

Tiziano

Hello tizianomattei.

Since you don’t want to install PulseAudio, try the tutorial Pipewire to manage audio in antiX 21 that Xecure created. If you are successful with PipeWire, please post the step by step you did here, as this information may be useful to others.

Já que você não quer instalar o PulseAudio, tente o tutorial Pipewire to manage audio in antiX 21 que o Xecure criou. Se você obter sucesso com o PipeWire, por favor, poste aqui o passo a passo que você realizou, pois estas informações poderão ser úteis para outras pessoas.

I very much doubt that pulseaudio will affect your performance a lot. I’ve installed pulse on several old laptops with no problem.

Hi marcelocripe and thank you for your answer.

I’ve had a look at it, and I’ll try it if everything else fails… however, I’d like to stay with pure ALSA if possible.

Hi punranger, ok let’s say that installing pulseaudio or pipewire will be my fallback.
However, in the thread I’ve posted above, installing pulseaudio is of no help to the user with the same problem.
So, I think the problem is up stream.

So at last I’ve decided to go with pipewire and all went fine!

I followed the post you linked step by step (1 to 5, included all the optional ones), I rebooted and everything worked.
I’ve tested several apps that used ALSA and I also tried recording and playing audio in Audacity through jack, with almost no problem. The only bug I’ve noticed is that when I changed the audio interface using the pulldown in Audacity while pavucontrol was open, Audacity would freeze until I closed the mixer window. So, pavucontrol must be closed while choosing a different interface in Audacity.

No problem with my bluetooth earbuds, either.

The only thing I was missing was a volume control applet for the panel, as volumeicon was now useless. So I searched for a volume control applet to run in the system tray (I’m using JWM so it had to be a systray applet) and I found volctl (https://github.com/buzz/volctl), which compiled gracefully and is just what I wanted.

I hope this helps!
