no simultanious audio to built in and HDMI

English Multimedia
#1

I can have audio only on either built in speakers OR HDMI.
(OS 15.3, KDE / plasma)

in plasma -> system settings -> hardware -> audio -> advanced I activated “virtual outpput device for all local souncards”
available output options are then
“Internal audio analog stereo” and
“simultaneaous output to Internal audio analog stereo”
Having a simultaneous output to the same device doesn’t make sense to me.
(same if HDMI is selected as output: then the simultaneous output is as well HDMI)

how can I have audio on both built in speakers as well as on HDMI?

#2

… interesting:
when adding a bluetooth headset, then I can have simultaneous audio output to the headset and to EITHER HDMI or built in, but still no simultaneous output between HDMI and buit in

#3

In pipewire it is not possible.
If you are using pulseaudio it is possible by installing paprefs.
Enable simultaneous sound in paprefs.

#4

as you can see from my posts, simultaneous sounds is already activated. I set it via pavucontrol.
the problem is that no all sound devices can be simultaneous, ie. HDMI can not be simultaneous with the built in analog audio of the laptop.

#5

When you said pavucontrol. You activated the simultaneous sound using “paprefs” right?

#6

I activated to add a virtual output device for all local sound cards in KDE/plasma system settings.
in paprefs it was therefore already activated.
in (eg.) pavucontrol I select the simultaneous output that is available

I’m sorry about that. I don’t have the Leap 15.3 to try.
I am using tumbleweed with pulseaudio and the simultaneous output is
perfectly working here. I am using xfce and I use the pavucontrol for my audio.
