I have a Latitude E7470 and while my 3-ring headphones with built-in mic work just fine plugged directly into the laptop, the microphone function stops working when I connect them to the headphone/mic ports on an e-plus II docking station (using this adapter).
Prior to getting this setup, I had an older Optiplex desktop (Win7), and my headphones/splitter adapter had no issues - the headphone function worked and so did the mic.
System info: Windows 10 Enterprise, v1607 and Realtek Audio driver 188.8.131.5211
These are my current settings:
Any idea what's wrong? Again, the headphone functionality works (either when I use my headphones with splitter adapter, or plug them directly into the docking station headphone port), but the microphone doesn't - I can't record any sound even though, from the screenshot above, it appears to recognize a mic has been plugged in.
Thank you for your message.
This dock model has an individual headset & mic port & does not support headsets with a mic built in.
You will need to use a standalone mic connected to the mic port in order for this to work.
Yes, I know the docking station has an individual headset & mic port. I plug the headphones into a splitter adapter which in turn plugs into both the headset & mic ports like this:
Again, I used this same adapter on my old Optiplex desktop to split the headphones into separate headset/mic plugs, and it worked. Why doesn't the docking station recognize the adapter? Has anyone else successfully used a similar adapter...?
