I just set up my new UD-3900, and everything seems to be working swimmingly but for the audio. Plugging my headphones into the headphone jack on the Dock, I get no sound - plugging the same headphones into my laptop’s audio jack works just fine, as normal. (I tested with Netflix and Youtube.)
For what it’s worth, I’m working on a Toshiba Satellite S855, Windows 10.
I looked into other similar problems on your forums here, and it looks like (at least part of) my problem might be that the Dock doesn’t show up in my list of Playback devices in the Sound Control Panel. It isn’t hidden or disabled - it just doesn’t show up:
Any ideas on what I might do to get my computer to recognize the Dock as a USB Playback Device / make the Dock realize it’s a USB Playback Device? Is there a driver or something I could install in addition to whatever was on the included CD?
Thanks very much!
