Fedora 35 Workstation withoud HDMI audio with pipewire

Dear colleagues, I’m starting to use fedora, and I faced an issue with HDMI audio here. It simply does not work. Internal audio goes OK.

I tried to follow some commands from another thread, however withoud success:

The command
rpm -qa|grep -iE ‘pulse|wireplumber|pipewire’|sort

Returns the following:
gvncpulse-1.3.0-1.fc35.x86_64
pipewire-0.3.48-1.fc35.x86_64
pipewire-alsa-0.3.48-1.fc35.x86_64
pipewire-gstreamer-0.3.48-1.fc35.x86_64
pipewire-jack-audio-connection-kit-0.3.48-1.fc35.x86_64
pipewire-libs-0.3.48-1.fc35.x86_64
pipewire-pulseaudio-0.3.48-1.fc35.x86_64
pipewire-utils-0.3.48-1.fc35.x86_64
pulseaudio-libs-15.0-2.fc35.x86_64
pulseaudio-libs-glib2-15.0-2.fc35.x86_64
wireplumber-0.4.8-2.fc35.x86_64
wireplumber-libs-0.4.8-2.fc35.x86_64

and

sudo systemctl --user --now enable wireplumber

returns an error:

Failed to connect to bus: $DBUS_SESSION_BUS_ADDRESS and $XDG_RUNTIME_DIR not defined (consider using --machine=@.host --user to connect to bus of other user)

If I change to my user in this computer:

[gisseh@fedora ~]$ sudo systemctl --machine=gisseh@fedora --user --now enable wireplumber

Failed to connect to bus: Host is down
Failed to enable unit: Ponto final de transporte não está conectado

Is there a way to change from pipewire to pulseaudio for instance? This laptop uses to work fine with HDMI audio with Ubuntu.

Thank you all in advance.

PS: This machine is a DELL Laptop with NVIDIA MX130 graphics, where I tried both using the 510 NVIDIA driver and also with the INTEL 620 integrated card, no difference to the external audio though.

Dear all, searching around I found someone telling about the package “pavucontrol”.

I just installed it and on Settings selected Built Audio as Stereo output HDMI and then everything just worked!

Thank you all.
