I have a Dell Vostro 3500 with Windows 10 20H2. At some point, my laptop just stopped detecting headphones when I plugged them in. I have seen many other people facing this issue but not a single solution I have found anywhere applies to me. Either it doesn't work or that solution isn't applicable to my system as I don't have the same system or drivers or software. And I don't know if it's related but MaxxAudioPro does not work on my system. Every time I try to open it, it says that the Waves audio driver is not supported by my audio codec. And today, my the speaker icon on the system tray also stopped responding to any clicks. When I left or right click on it, nothing happens. This is despite multiple restarts.
