<SOLVED> Sound Applet - Hide unused devices

[janlev]

Hi new Linux user here. How do you disable/hide unused sound devices from the sound applet? I change outputs quite often and don't like the way it's bloated with outputs I never use. I tried googling and asking on IRC channel, but haven't found a working hiding/disabling method.

I only need from outputs:

• Digital Output (S/PDIF) - Built-in Audio
• Line Out - Built-in Audio
• Analog Output - DigiHub USB Audio

Input: Only Microphone - Blue Snowball

64-bit Linux Mint 20.3 with Cinnamon 5.2.7 - 5.13 Kernel

Code: Select all

Solved it on my own. I modified the applet sourcecode to filter out unwanted devices.
The source is located @ /usr/share/cinnamon/applets/sound@cinnamon.org/applet.js

Added:

Code: Select all

	if(type == "output")
        {
            if(device.origin == "GP102 HDMI Audio Controller")
            {
                return;
            }
            else if(device.origin == "DigiHug USB Audio" && device.description == "Digital Output (S/PDIF)")
            {
                return;
            }
        }
        if(type == "input")
        {
            if(device.origin == "DigiHug USB Audio" && device.description == "Analog Input" || device.origin == "DigiHug USB Audio" && device.description == "Digital Input (S/PDIF)")
            {
                return;
            }
        }

Under:

Code: Select all

    
    _onDeviceAdded(control, id, type) {
        let device = this._control["lookup_" + type + "_id"](id);
