How to delete an output audio device?

Support Sound
,
1

I am using Manjaro Gnome, and I have 2 output devices for audio, one is the HDMI but there is no audio in my monitor, and the other is the notebook speakers, and always when I unplug my headphone it selects the HDMI device, and my sound stops to work.
There is a way to disable or delete this output device?

Here is my inxi -Fazy

Hi @andutra,

AFAIK that module is responsible for HDMI audio. So let’s test if removing it works first:

sudo modprobe --remove snd_hda_codec_hdmi

And test. If it works, we make it permanent, if not we simply reboot.

Edit:

I realized my way might be a tad complicated, so see here:

https://www.addictivetips.com/ubuntu-linux-tips/how-to-turn-sound-devices-on-and-off-in-linux/

Specifically the Gnome section.

The module was in use, but I put it in the modprobe blacklist (I will restart to see if it will work).
I went to this link, but all I saw is how to select the output audio, I am doing that already, what I want to do is to remove this HDMI to avoid me forgetting to select the speakers back when I unplug my headphone.

If that is what you do already, and it’s not what you’re looking for, then don’t worry 'bout it.
