From time to time, my audio keeps cutting out randomly while I'm in the middle of something I ought to be hearing. In the Volume Control window on the Playback tab, I found that when this happens the setting has been changed from Starship/Matisse HD Audio Controller Analog Stereo (my speakers) to Navi 21/23 HDMI/DP Audio Controller Digital Stereo HDMI 5 (my monitor and its built-in speakers) for all the windows. I have already set the volume of the monitor to 0 both in directly in the monitor through the physical buttons and in the Output Devices tab of Volume Control AND hit the Mute Audio icon. Despite this, several times within a day has my audio cut out because Garuda, through no provocation, switched to using the monitor as the playback device for all my active windows.
