I just bought a UD-3900PDZ. The USB, Network and DisplayLink works fine. But when I connect my headphone, there is no audio. It is not a big issue, because I can connect it directly to my macbook m1, but I wonder if it is because my headphones does not have microphone or is it some other soft/firmware issue.
I did follow the recommendation in the knowledge base, to go on audio settings, select as output and make sure is not muted or low volume.
Is there something I am missing?
Thanks for reaching out to us, I am sorry this is not working as expected and I am happy to help!
The 3.5mm TRRS (headphone+micropohone) port should work just fine with a standard 3.5mm headphone without microphone. MacOS will not automatically select the docking station as the output device, but it should be easy to manually select the output, when you have a moment please try the following:
Connect the docking station to the computer using the provided USB-C cable, and connect the headphones to the docking station’s 3.5mm audio port
On the macOS desktop, click on the quick settings menu ( two horizontal toggle switches right next to the clock )
Thanks very odd behavior that is not at all expected.
If you don’t mind, I would like to get some additional information from your system to help look into why the docking station’s audio is not being added to the quick menu and not functional when selected.
If you would, please keep the dock connected to the computer with headphones connected and attach the output of our diagnostic utility PlugDebug ( http://plugable.com/support/plugdebug ) to an email to ‘support@plugable.com’ with the subject line ‘Ticket #328866 - Attention Pat’ as this will allow us to examine some log files from your system to help determine the next steps.
Additionally, in the body of the email, please let me know how many displays are connected to the docking station and which ports have a display connected ( each port should be labeled as “HDMI #” on the back of the dock.
Thanks for these additional details, I look forward to your email.
I think I figured it out, but I don’t know how to solve without a software for that.
My monitors have audio output. The dock is sending the audio to my monitors via HDMI instead of the 3.5mm audio jack. Is there some kind of software to route the audio to the desired port, either HDMI or audio jack, depending on the user need/will?
I did a last test. I plugged everything off, all HDMI, just connected the USB-C and the sound still did not work. I think it might be a problem with my dock only.
Thank you very much for the replacement, it works as intended with good audio. Totally recommend buying from Plugable. Thanks Pat for the nice experience for customer support.
Thank you for letting me know the replacement has arrived and is working as expected.
I will go ahead and close this thread.
