Output audio problem since last update

Hi there,
Until a few days ago all was ok on my devuan + xfce desktop. Then I did a system update.
After the update the default audio card is selected on each system boot.
Before the output selected was 'hdmi 2' and now it's 'IEC 958 Output' wich should be the computer sound card wich is the first working device (IE not unplugged).
If I run the audio selector and select back 'hdmi 2' all is ok but this is dropped on each reboot and I have to select it again sad Real pain for an HTPC.
I've done my homework and tried to add set-default-sink and set-default-source in pulse audio config file and then remove all ~/.config/pulse directory but it did not solve the problem.
It seems to me that pulse audio is utterly complex so I need your help there.
Some hints ?
This is latest Devuan version 2.0 updated.

Please post your configuration files.

pactl only list the active sink but in the graphical tool I can see more than 15 sinks and at least 5 or 6 not tagged 'unplugged'.
So there, the correct sink :

pactl list short sinks
2       alsa_output.pci-0000_00_1b.0.hdmi-stereo-extra1 module-alsa-card.c      s16le 2ch 48000Hz       SUSPENDED

But just after boot it's set to the wrong output despite the set-default-sink 2 in the config file :

pactl list short sinks
0       auto_null       module-null-sink.c      s16le 2ch 44100Hz       IDLE

Re: Output audio problem since last update

That is strange, the configuration file should work (I think).

Is there anything in the logs?

It may be worth trying pavucontrol to see if changes made by that program "stick" for the next boot.

Or add the relevant pactl commands to your desktop startup file(s).

EDIT: try putting your configuration in ~/.config/pulse/daemon instead (if that's not where it already is).

Re: Output audio problem since last update

pavucontrol is the default tool on XFCE so that's the tool I use to set the sound each and every boot now.
Wich command should I use to configure the sound in command line ?
Nothing much in the logs but :

May  5 08:21:23 ht-PC pulseaudio[3226]: [pulseaudio] main.c: Sink 2 does not exist.
May  5 08:21:23 ht-PC pulseaudio[3226]: [pulseaudio] main.c: Source 2 does not exist.

since I try to set the good sink @boot.

Re: Output audio problem since last update

Well, I gave up the fight against pulseaudio and reinstalled the HTPC.
This time I installed MX Linux.
Another distro based on Debian.
That takes me the day but all is ok now.

PS: I nearly broke the computer while preventing the cpu fan to spin but after a hard reset and some times for the cpu to cool from 105 to 30 it's ok now.
