Hi @spacedesker,
The settings we were talking about can be found in the spacedesk Viewer app in your phone.
about the audio, are you using Native USB connection or Wi-Fi connection?
if it’s Wi-Fi, while Android device is connected to your PC display, you will see a floating menu with three lines on it, please tap that menu and check the audio option to enable it.
if its already checked, and still has no audio, the issue could be in your windows audio settings. just choose “spacedesk virtual speaker” as your speaker output.
