Just curious: Does the sound work in devuan when using /etc/modprobe.d/alsa-base.conf from ubuntu?

Tried that too!

Doesn't work.

Hello vrgovinda,
patience be with us!
the archlinux sound documents are very excellent, the main two documents.

I am actually trying to 'configure' my new mini-pc (with it's spurious codec,) at the moment, so my input here is actually in practice say.
I don't think I am going to get sound line-out AND HDMI, I think I may have to settle for one or the other, we will see.

The last twenty-five years alsamixer has been good to me, pulseaudio is new to me.
I have apt-get --no-install-recommends install pavucontrol pulseaudio which pulls in all the required packages.
In addition I have made a folder _pa and in that folder I have downloaded the two packages pavucontrol and pulseaudio.
When I want to certainly work on alsa I, dpkg -P pavucontrol pulseaudio.
And when I want to work on pulseaudio I, dpkg -i -R _pa.
So I can keep trying, and don't have to be online.
When I do use pulseaudio I'm always in user not root, and I always pulseaudio --start | --kill
I always run alsamixer as it changes when I install/uninstall pulseaudio.
The sound file I work with is FILE.WAV, aplay in alsa plays WAV file.
vrgovinda, please keep trying with all those too many settings in alsamixer.
All this quasi pain is worth it to advance learning howto configure sound. I think!
Andrew.

Oh yes! I'm very patient. At the same time, excited too. No problem. I'm also loving this learning. Else, I would've settled with the pre-installed OEM Ubuntu.

With Linux, one has to be patient and that is “mode of goodness”, according to the Bhagavad-gita.
At least, I got the HDMI sound output. That's a good deal.

Thank you so much Andy. You are a good soul.

Marking this post as solved, albeit partially. [HDMI only]

Regards,

Just wanted to update.

I had recently installed Devuan Daedalus on another partition. Instead of tweaking /etc/modprobe.d/alsa-base.conf, I just installed firmware-sof-signed. Everything is working perfectly. I get a neat click-and-choose options beneath the volume icon and I can just choose the input and output devices. That's super convenient.

I tried this in the other partition which had Daedalus and on which I was trying to play around. But microphone input still doesn't work. Maybe I have forgotten all that I have changed and don't know how to get back to the default configs.

So my mantra is : Next time I install Devuan on an Intel machine, I'll first install firmware-sof-signed and check if everthing is alright. If some issues exist, I'll try other options. Don't know what is the mantra for AMD machines.

It seems that the problem was in pulseaudio.
It means that sound may disappear in any moment.

Repeated for truth! It has always been so from day one!

^^^For sure, it's been junk since the get-go.

Last time I installed Devuan and chose Mate in the software section, it automatically included pulseaudio. Really IMO no "sound server" should be included on install of any DE, but at the least Devuan ought to de-couple pulseaudio from the Mate metapackage and at least use pipewire instead.

Me I never run anything but pure alsa. Works just fine.

All problems with Mate (Gnome2) and ALSA were already solved in 2009 (Mate is a fork of Gnome2).
gnome-media (deb) was recompiled and patched by the OSS4 community.

Today, if you remove PulseAudio, Mate will install PipeWire (and other way round).
If you remove them both, Mate will automatically enable ALSA for mate-settings-daemon and mate-volume-control-status-icon (sound applet in the tray)

$ sudo apt-get purge pulseaudio pulseaudio-utils pavucontrol pulseaudio-module-bluetooth pipewire pipewire-bin pipewire-pulse

This will also remove "mate-desktop-environment". It is a meta-package which can be safely removed.
Then, you have to reboot, or kill pulseaudio and reload ALSA

$ sudo /etc/init.d/alsa-utils force-reload
Shutting down ALSA...done.
Setting up ALSA...done.

On Linix Mint MATE, you should also remove pipewire-alsa, etc.
