Hi

You get the list from "aplay -l" which you have given above. Seeing all files from the commandline "ls -a". Editing the file (as root) with "nano /etc/modprobe.d/alsa-base.conf" and add the two lines suggested in the previous post. Save and reboot. The numbers could as well be 0,0,1,0 or 0,0,0,1 depanding on the hdmi port you are using for your display. Hope this help. And as stated above, my advice could prove to be wrong. I am just suggesting what I would try myself ;-))

Hi

From what I see the problem is not related to multiple sound devices as you have only one. What we need it to do is to let you get sound via hdmi, and not through the builtin speakers.

The file I think you wan to edit is /etc/modprbe.d/alsa-base.conf (or call it something else with *.conf in that directory) Assuming your screen is on hdmi0

# Disable the HDMI card which shows up first, but enable PCH
options snd-hda-intel enable=0,1,0,0

If your screen is plugged into another port adjust the 1 accordingly.

I hope this is to some help. I do not have this problem myself. But if aint broken dont fix it.

Hi

You might have created a monster devuandebian. with parts from different distributions and versions. If you did get installed something from debian buster, you have at least upgraded some of the main parts of your system (libc among others). As I see it you have three options:

1) You might try to downgrade by using apt-get -t ascii dist-upgrade. Look carefully what it want to do. It might fail because downgrading is not supported

2)You might try to upgrade by changing your sources to beowulf. Run apt update, and then apt-get -t beowulf dist-upgrade. Look carefully what it want to do. It might have problems due to different packages between debian and devuan

3) Reinstall. That I am sure will do it.

Hi

And as professionel I am using jack for most of this when it really matters. It reduces latency together with alsa, which in that situation is the most important thing. I also think using pulseaudio is much simpler for the programmer, because he does not need to take care of a lot of small details. But on high end gear I can hear a difference between pulseadio and alsa because of the higher latency.

Hi

It looks like you get sound working ;-)

I am a professional musician myself using my setup for everything. And I have removed all of pulseaudio. Using firefox, vlc, mpv, audacity, musescore with just alsa. And for professional work I use jack as audioserver.

Make sure your /etc/pulse/client.conf.d/00-disable-autospawn.conf looks like this:

# On linux systems, disable autospawn by default
# If you are not using systemd, comment out this line
autospawn=no

Then you should be safe that pulseaudio is not working. If you find any problems then try uninstall and purge pulseaudio with apt purge pulseaudio. Then apt will also remove pulseaudio configuration files (that might be your problem)

Hi

Do you have multiple soundcards ??. Take a look with "alsamixer" in a terminal. F6 will allow you to choose and set your default soundcard. You can also choose soundcard in volumicon by right clicking and choose preferences. Hopefully this is your problem. If not we have to look a littel deeper. But the simple things first ;-))

What about

"Devuan workaround wiki"

It could over time contain quite a lot of stuff. Systemd related. How to avoid unneeded services. Upgrade solutions. And many others.

Hi

You may be right about that one. But it can be solved by enviroment variables ;-)). For serious sound I am using jack anyway. Pulseaudio  and jack are no good to  use at the same time. But that is offcourse my special case.

Hi

Or use volumicon-alsa if you want a graphical application

Hi

Will just mention that instead of enabling pulseaudio. Witch is software only and adding overhead and latency to your system, you can install volumeicon-alsa instead and add it to your desktop startup.

Hi

Use btrfs. As long you do what the debian wiki suggest you should be very safe https://wiki.debian.org/Btrfs . Snapshots takes very little space (and time). I hav been using btrfs for a long time. I have used compression but today I am using it without. It makes it a lot faster and avoids trouble.
