Surface Pro 7 external Micro doenst work

Question

There is a known issue with the 3.5 plug, in general. For other devices I have a audio manager to switch the socket from 4 to 3 pole between headset or just Microphone usage

Some devices can auto detect which kind is pluged in.

My surface pro 7 doenst detect the pluged micro correct. If i plug a headset external Microphone is used, If i plug a Microphone mit 3 pole on 3.5 plug, still internal micro is used.

Question: can Surface Pro 7 auto detect 3.5 plugged devices, is there any settings, addon tool ?

Answer 1

I'm having the same issue. 

Trying to use a mixing board to send audio output from a mic to the Surface. Using a 3.5" 3-pole jack to connect the mixing board to the surface, but because it's a 3-pole jack, the Surface thinks it's regular headphones (shows up in Device Manager) but won't recognize it as audio input.

Is there any way to force the Surface to treat a 3-pole jack as audio in?

Answer 2

Hi HannesPreishuber,

Thank you for reaching out Microsoft Community. We apologize for the inconvenience this may have caused.

I am quite confused with what you have posted and to clarify, are you trying utilize the USB- A port of a Surface Pro 7 to use an external microphone or headphone with the use of a 3.5 mm audio adapter?

The Surface Pro 7 has a 3.5 mm headphone jack and that's where you'll connect an audio device to get it to work. Please let us know clear details so we can further assist you on this since the Microsoft Surface Pro 7 has input and output ports that has its own purpose and this is something I can discuss to you.

Kind Regards,

Answer 3

regarding your tipp, I did some tests.

1. plug in a headset 4 pole - Sound settings have a new device Headset and Microphone Array
2. just plug the Mic from same headset 3 pole- ( use a adapter from 2x 3.5 to 1) - single Microphone Array
3. plug in Rode Wireless go -3 pole - single Microphone Array

4 plug in rode with adapter and let the loudspeaker free - Sound settings 2 devices- Headset +Microphone array

summit- detection doenst work for 2 types of 3pole microphone on that surface pro 7

Answer 4

Hi HannesPreishuber,

Thank you for your response. 

It should auto detect a 3.5 mm audio device but some audio devices to be connected on the host device should have an app associated to it that helps in updating the firmware of an audio device. Can you tell me what's the brand and model of this audio devices so I can further check relevant information about it? 

Kind Regards,

Answer 5

I have with no word written USB NO- NO USB

the "headphone" jack

repeating -there are devices (headset, micro) using 3 pole and 4 pole. Most modern Notebooks make a detection on Impedanz of device and auto switch.

Other vendors are shipping tools like realtek HD audio manager to let the user switch.

this is a common issue

Question: does surface pro 7 support that, is there any tool? 

btw I am quite sure that former surface pro devices did this job sucessfully

btw2: Im not a enduser - Enterprise admin knowledge level - as you suggest next to do some update
