Speakers Not Working!

Hi all,
It seems like I’m having a similar problem as some others, but external speakers are not working when using the UD-3900 Plugable device when connected via USB, but will work just fine when I plug the headphone jack into the laptop directly. In the Playback devices menu the external speakers don’t even show up when using the plugable, but do when I directly plug in. I’m using Windows 10. This has worked previously, but all of sudden stopped!

Please assist!

I will follow up with a direct email asking for logs.
