Hi - I have a USB 3.0 Docking Station and am connecting to it with my Windows 8.1 Samsung i7 Ultrabook with DisplayLink_7.6M0 driver installed . I have some simple HP speakers hooked up the the plugable and they have worked in the past (with the plugable), as has the ability to just plug headphones in.
I don’t play music from them much so not sure when issue started but I am no longer getting sound through the headphone jack. The Sound | Playback settings indicate that it is using the plugable and sound going through (volume bar indicates activity when playing sound) - see attached.
I can plug speaker jack direct to computer but I do use several other computers for docking station and brag about my plugable all the time so would love to continue the one and done connection.
