Any boot messages should show in the dmesg information. You must have root or sudo access to view the output of this.

sudo dmesg | less

Yes pulseaudio is dependent on alsa. What is the output of amixer (on cmdline). Also try alsamixer and see if you are using the right device, or if is muted.

What is the output of arecord -L

I did install between my 2 last messages a bit more but I did loose the overview about what I did.

But: the sound did work until I did shutdown for lunch.

Restarting it was away again :-(( !

Restarting once more, I did see a short time a boot message appearing in red (difficult to see as my computer is so fast and my English is bad! The boot system from Linux is really archaic!!! Why messages you don't can read!!! It is absurd!!!

Restarting one more, I did see just the time to understand it in my bad English:

the kernel modules adapted to the oss (open sound system I did install with other little packages like alsa-tools, alsa-utils etc. after an action

# sudo apt search sound

have not the adequate module for oss.

this is a really tricky situation for me as it did never happen in all the years I use Linux (since 1995 ;-) ...

I did never have to manipulate the content of kernel...

Is that easy or will I have to spend for nothing a lot of time in a matter having not really the profit of?

can I get a adequate ready to use kernel somewhere?

Is OSS (or alsa) a MUST dependency of pulseaudio? why did pulseaudio not work immediately well as installed without that chaotic more installation?

sound is a very very important performance today for each OS. in SID I did not meet such a problem (but did not install very minimalist from Devuan Star, of course, but from a weekly ISO with, theoretic, XFCE4 who was not able to be installed...

There migth actually be a file  /etc/pulse/client.conf.d/00-enable-autospawn.conf. Try to edit that from yes to no

Thank you very much.

There is no such file in my installation: If I try to open it, it is empty!

I did create some one with only this line but as it is a commented line, I don't hope it can be usefull...

The package pulseaudio in Devuan seems to be really uncomplete ...

(no really enough dependencies... no settings....)

Pulseaudio
 - If you install a desktop environment from the installer iso, you will
   automatically get the debian-pulseaudio-config-override package,
   which will ensure that pulseaudio is running. If you're running a
   window manager, you may need to install the override package to get
   sound. Alternatively, you may use the old method, described below.
   
 - If you have no sound, make sure the following line in
   /etc/pulse/client.conf.d/00-disable-autospawn.conf is commented as
   shown here:

   #autospawn=no

Maybe this helps.

no sound :-(

an idea how to make the sound better?
