How to set priority for Sound Output Devices in Gnome

  • 772

Using Ubuntu 19.10 I have 3 output devices in Settings -> Sound -> Output-Device:

  • HDMI (monitor)
  • S/PDIF (onboard)
  • Headphone (onboard)

AMD 2400G, Asus PRIME B450M-A

I need this priority:

  1. Headphones
  2. HDMI
  3. S/PDIF (unused)

So it should switch to headphones if plugged in, otherwise HDMI.

Now it starts with HDMI, no matter if headphones is plugged in. When I select headphone, and later unplug headphone, it falls back to S/PDIF which is not used at all.

Shouldn't the GUI offer a draggable list to order my preferences? I kinda like the simplicity of Gnome GUI, but sometimes it's too minimal.

How do I set priority?

  1. I don't know how you would set priority, but there is a way to shut off the S/PDIF. Open Pulse Audio Volume Control and turn off S/PDIF. It should disappear from the Volume Settings list. (found here - https://askubuntu.com/a/1186737/150363)

    As for the headphones bit, you may still have to manually choose them, but when you unplug (if you followed the above), it should go back to HDMI.
