Normally the audio works. in alsamixer, use arrow keys to move left/right to select a channel, m to mute/unmute a channel, pgup/pgdown to raise/lower volumes. ESC to exit when you're done.

Post the output of aplay -l Let's see how many audio devices you have and what they are.

Since the analog out put is on your card 1, you should create a file
/etc/alsa/conf.d/00-defaults.conf with the following line:

defaults.pcm.!card 1

Thank you Fred & Ralph. However Ralph, I could not create the file < /etc/alsa/conf.d/00-defaults.conf >
$ ls -al /etc/alsa
ls: cannot access '/etc/alsa': No such file or directory
???
Should I just create empty < alsa > & < conf.d > directories?

Yes, create the directory pathname

# mkdir -p /etc/alsa/conf.d

if it doesn't exist.

in fact, if you look into /usr/share/alsa/alsa.conf which is the main configuration file for alsa, you will see that it looks for configuration files in many places. I suggested /etc/alsa/conf.d/ because that is commonly used by many packages and especially bluez-alsa-utils (which provides a virtual sound card for playback and capture via bluez bluetooth mediation).

Some people prefer using ~/.asoundrc instead, since that is written/editable by the non-root end user. However it will also only be used by that non-root end user and not shared among all users.

Re: RefractaOS - (Devuan Daedalus Based) Fresh Install SOUND OK XCEPT4FBK?

You may post the output of this command:

fuser -av $(find /dev/snd -type c 2>/dev/null)

For example:

➤ fuser -av $(find /dev/snd -type c 2>/dev/null)
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  igor       2235 F.... mate-settings-d
                     igor       2326 F.... mate-volume-con
/dev/snd/pcmC0D0c:
/dev/snd/pcmC0D0p:   igor       3201 F...m firefox-esr
/dev/snd/seq:
/dev/snd/timer:      igor       3201 f.... firefox-esr

And the output of

inxi -A

sudo apt install inxi

bluez-alsa-utils (which provides a virtual sound card for playback and capture via bluez bluetooth mediation).

It seems that it does not provide any "virtual sound card".

What it does provide is a sort "virtual PCM device" named "bluealsa"
_https://github.com/arkq/bluez-alsa

aplay -D bluealsa test.wav 

alsamixer -D bluealsa 

 $ bluealsa-aplay -l
**** List of PLAYBACK Bluetooth Devices ****
hci0: EC:66:D1:BF:02:05 [Godess of Wisdom], trusted audio-headphones
  A2DP (SBC): S16_LE 2 channels 48000 Hz
**** List of CAPTURE Bluetooth Devices **** 

It can be configured as default playback device, e.g. ~/.asoundrc.

The question is how to configure a dmix for it.

EDIT:

Unfortunately dmix works as a front-end only with hardware (ie "hw" type) devices, and not with any other plugin types such as BlueALSA.

So it is not possible to configure BlueALSA as a backend device for dmix. We are forced to find an indirect method; that is, use a "hw" device that can forward the mixed stream on to a BlueALSA PCM. Fortunately, ALSA provides just such a device, the "Loopback" device, which is a kernel driver that implements a virtual sound card.

This wiki article describes one way that BlueALSA can be used with the ALSA Loopback device and the dmix plugin to achieve mixing of multiple audio streams into a single BlueALSA playback PCM.
_https://github-wiki-see.page/m/Arkq/bluez-alsa/wiki/Using-bluealsa-with-dmix

A very simple ALSA config for Bluetooth Headphones:

$ cat ~/.asoundrc
# -------------------------------------------
#		Bluetooth Headphones
#
#	Configuration for default audio device
#--------------------------------------------

# Perform plug device
pcm.!default
{
	type	plug
	slave.pcm	"bluealsa"
	hint.description	"Default device"
}

bluealsa is a Linux daemon to give applications access to Bluetooth audio streams using the Bluetooth A2DP, HFP, HSP and/or BLE-MIDI profiles. It provides a D-Bus API to applications, and can be used by ALSA applications via libasound plugins (see bluealsa-plugins(7) for details).
_https://manpages.debian.org/unstable/bluez-alsa-utils/bluealsa.8.en.html

$ apt-file find /usr/bin/bluealsa
bluez-alsa-utils: /usr/bin/bluealsa       
bluez-alsa-utils: /usr/bin/bluealsa-aplay
