To resolve the issue, the first step is to ensure that the default audio playback device in Windows is set to 'Displaylink Audio'. To check and modify this setting, simply click on the small 'speaker' icon located in the taskbar at the bottom right-hand corner of your desktop (next to the date and time).
Upon clicking the speaker icon, a small window will appear displaying the current default audio playback device. If multiple audio options are available, click on the upward facing arrow on the right-hand side of the list to view all available choices.
Select the 'Displaylink Audio' option from the list of choices and set it as the default audio playback device.
