Hi Jeffery,

If you depend on speech to use your system, it might be wise
to have someone helpful around before fiddling with the
sound. In particular, ALSA has a bunch of mixer settings,
and for years when people doing a new linux installations
would complain about not having sound, one or another mixer
setting being muted.

There is no guarantee what state pipewire or pulseaudio
will leave the sound devices when disabled. So you'll
want an unmute script available.

Here's a reference for commands (or a script) to 
unmute various ALSA parameters. 

https://bbs.archlinux.org/viewtopic.php?id=124769

I would compare the parameters in the script to the
parameters listed in `amixer scontents` to be sure it
corresponds to my hardware--I think they're the same for all
soundcards. 

To not fiddle with your package dependencies, it makes sense
to start with *disabling* your sound server rather than remove
it entirely. 

For pipewire this looks simple, just two steps.

However for pulseaudio it is complicated, taking three
answers by three authors to clarify:

https://askubuntu.com/questions/1197420/how-do-i-stop-pulseaudio

When you get pulseaudio/pipewire stopped, you'll need to
restart your screenreader software so it will access the
ALSA device now exposed.

Now run your unmute script if necessary.

Through all this you haven't altered your software
configuration, so you're always able to reboot to get back
to a previous configuration. Once you've verified that you
can do your work with bare ALSA, you can remove the
pulseaudio or pipewire package.

To me pulseaudio and systemd (written by the same author as
pulseaudio) add a lot of wrinkles to administering a linux
system, more than is justified by their capabilities, which
are available elsewhere in small, discrete libraries.

I migrated from debian to devuan to avoid introducing the
complexity and huge attack surface of systemd. 

Good luck configuring your audio!
