It seems to be a philosophical problem. You may find such instructions in Arch Wiki.

Perhaps, you need SLiM manual

FreeBSD has own fork of OSSv3, but OSSv4 is also available for FreeBSD.

OSS4 now exists mostly as a standalone piece of software, not integrated into the kernel source code. The exception is Solaris and OpenSolaris, which use a fork of OSS4 called Boomer. It combines the OSS4 framework (audio and mixer) together with Sun's earlier SADA (/dev/audio) API.
_https://en.wikipedia.org/wiki/Open_Sound_System#Code

It seems that the main problem of ALSA is crappy resamplers.
That is why, it might be interesting to try Petrov's fftrate.
It is easy to compile _https://dev1galaxy.org/viewtopic.php?id=6644

The default setting for fftrate ALSA plugin can be easily produced with arateconf. They include a software mixer. It might be needed simply because Intel HDA codecs do not have hardware mixers.

There are professional sound cards which have HW mixers, but such cards are very expensive, and they may not have Linux drivers.

_https://en.wikipedia.org/wiki/Digital_eXtreme_Definition
ALSA RAVENNA AES67 Linux Driver (Merging Technologies)
_https://www.merging.com/support/downloads#alsa-linux

Since Petrov's fftrate supports DXD format (24bit 352.8 kHz), you can play DXD waves and flacs with Audacious on a notebook with Intel HDA codec (fftrate should be configured for 32bit 192kHz, if you want to have a good sound quality). DXD music is available on HDtracks.

And why do you need such an old audio system?

Because of sound quality.

stopAI wrote:

Sure, we can build a deb package, but there's no guarantee it will work....

Yes, this is the problem.
OSS4 packages (which work) have been available in Arch Linux repositories since time immemorial.
Debian developers did try to build OSS4 packages for Debian, but they always failed to work.
There were OSS4 packages in Ubuntu repositories. They did not work, but they were easy to install (and difficult to remove).
They are still OSS4 packages in Debian testing, which do not work.
On the other hand, it was not a problem for Ubuntu newbies to compile working OSS4 packages themselves.

The main problem is that an OSS4 driver for your sound card may not be available.

Perhaps, it might be more reasonable to patch Petrov's fftrate for gcc-12 and build deb packages for Devuan.
With Petrov's ALSA plugin, you can get a very good sound quality on a notebook with Intel HDA codec (motherboad).
Moreover, you can use video conferencing apps without PulseAudio. But you have to generate ~/.asoundrc with Petrov's arateconf and use apulse.

igorzwx · Freedom Hacks

Freedom implies the freedom of choice.
What kind of freedom is it, if you have only one sound system installed in your Devuan?

Although the so-called "upstream" tends to restrict the freedom of Linux users, it is not very difficult to compile OSSv4 for Devuan.
Patches can be found in the Arch Linux AUR package oss-git
_https://aur.archlinux.org/packages/oss-git
_https://wiki.archlinux.org/title/Open_Sound_System

If you have two sound cards (e.g. Intel HDA and USB sound card), you can use OSS4 and ALSA simultaneously.
The difference between OSS4 and ALSA is that OSS4 permits the so-called "exclusive mode":

man ossplay | grep virtual -A1
       -R     Disable redirection to virtual mixer engines and sample rate/format conversions. Should not be used un‐
              less absolutely necessary.

The OSS4 plugin for Audacious has an option "Enable exclusive mode to prevent virtual mixing". It is intended for playing high resolution audio files "as they are", without resampling and sound distortions produced by the software mixer (vmix).

Notice, however, that Petrov's fftrate is much better than OSS4 resamplers, so that, OSS4 can be dedicated for playing audio files in "exclusive mode", and ALSA for ordinary desktop usage (playing movies in youtube, video conferencing, etc.)

In a word, Intel HDA codecs support many audio formats:

ossinfo -v9 | grep "HD Audio play front" -A13
HD Audio play front               /dev/oss/oss_hdaudio0/pcm0  (device index 0)

    Native sample rates (min - max): 44100 - 192000 (44100,48000,96000,192000)

To enable the OSS4 plugin, you have to rebuild the package "audacious-plugins".
If you are going to compile something, it makes sense to install some tools:

sudo apt install build-essential devscripts command-not-found

mkdir audacious-plugins-rebuild

cd audacious-plugins-rebuild

Download the source code and install build dependencies:

apt-get source audacious-plugins

sudo apt-get build-dep audacious-plugins

ls -1
audacious-plugins-4.2
audacious-plugins_4.2-1.debian.tar.xz
audacious-plugins_4.2-1.dsc
audacious-plugins_4.2.orig.tar.bz2

cd audacious-plugins-4.2

To enable the OSS4 plugin, you have to edit "debian/rules"

cat ./debian/rules | grep oss4 -B2
override_dh_auto_configure:
	dh_auto_configure -- $(additional_confflags) \
		--disable-rpath --enable-gtk --enable-oss4

You can also edit "changelog":

cat ./debian/changelog | grep 4.2-2 
audacious-plugins (4.2-2) unstable; urgency=medium

Now you can rebuild audacious-plugins:

dpkg-buildpackage -us -uc -b

cd ..

ls -1 | grep .deb
audacious-plugins_4.2-1.debian.tar.xz
audacious-plugins_4.2-2_amd64.deb
audacious-plugins-data_4.2-2_all.deb
audacious-plugins-dbgsym_4.2-2_amd64.deb

Now you can reinstall Audacious:

sudo apt purge audacious audacious-plugins audacious-plugins-data
sudo dpkg -i audacious-plugins_4.2-2_amd64.deb audacious-plugins-data_4.2-2_all.deb
sudo apt install audacious

To prevent upgrade, you can pin them all:

sudo nano /etc/apt/preferences

cat /etc/apt/preferences
Package: audacious

Pin-Priority: -1

Package: audacious-plugins
Pin: release *

NOTE: If you want to rebuild a Debian package, which is not available in Devuan repositories
(e.g. _https://launchpad.net/ubuntu/+source/wxmaxima/24.02.1-1build2 ),
you can use these commands:

dpkg-source -x *.dsc

sudo mk-build-deps -i  # it should be executed inside the source directory

dpkg-buildpackage -us -uc -b

Cardinal de Richelieu asks the head of the Sécurité extérieure, during a military parade, "Sir, who are those guys in the plain suits in the parade?" "Oh," the Sécurité extérieure head answers, "they are economists, Your Eminence." And when Cardinal de Richelieu raises his eyebrows, he hastens to explain, " Just wait until we let them loose in the UK."

NOTE: The joke was found in Shumerian chronicles. Instead of economists, you can substitute any other scientists, depending on the context.

Yes, I may help you to "fool yourself", as Feynman put it.

Perhaps, you are missing the point. The victims of science are not able to see the obvious simply because they are intellectual slaves.

Science is a great art, and the great scientists tend to use the same simple trick to fool naive people.
First, they let you swallow a wrong assumption, then they derive a true theory from the wrong assumption.
The best example is, perhaps, "Cargo Cult Science" of Richard Feynman _https://calteches.library.caltech.edu/51/2/CargoCult.htm
If you cannot find the wrong assumption underlying Feynman's theory of scientific method, you may try to study the true Bible of Knowledge, that is, "Mambu" of Kenelm Burridge _https://en.wikipedia.org/wiki/Kenelm_Burridge

If you read the Gospel of Cargo cult movement, you may notice that Cargo cultists tent to use the method of trial and error not because this method was discovered in the United States of America, but because it was invented in the Stone Age.

I may not agree. Science is the art of deception. Have you noticed that nobody can explain what Knowledge is?
That is why there is a project of "Deschooling Society" _https://en.wikipedia.org/wiki/Deschooling_Society
What is obvious is that Knowledge restricts our freedom, especially the Knowledge of Physics. Because of gravity, you cannot fly like a bird.

I may agree, ignorance does make people free.

Knowledge you could hardly make people happy, and ignorance makes freedom possible. When slaves do not know that freedom exists, they may feel free. For example, the slaves of PulseAudio might be perfectly happy with PipeWire.

Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3D stereo sound sensation for the listener of actually being in the room with the performers or instruments.

Minimal HW requirements:

1. Computer with Intel HDA codec on motherboard.
NOTE: Very old computers (e.g. of 2006) may not have Intel codecs which support 32bit 192kHz.

2. A cheap analog headset (e.g. Sennheiser PC 3 Chat), or headphones.
NOTE: USB and wireless headsets are not suitable for the purpose.

Software: ALSA, fftrate ALSA plugin, Audacious.

Audacious → Settings → Audio → ALSA Output 32bit

To prevent resampling, configure fftrate for 32bit 192kHz (although, of course, 99.99% of Linux users may hear the difference, if resampling was made by Petrov's fftrate)
