I am using a Surface pro 6 that has one 3.5 mm head phone jack .
i want to use this jack for connecting external mic (Boya BYM1 Omnidirectional Lavalier ) and external Speaker (JBL GO)
Both mic and speaker has 3.5mm Jack. Both are working with 3.5 mm jack when connected independently. However i want to use both of them together.
I tried purchasing a audio splitter cable Splitter Link however found that speaker is working but mic is not.
What am i doing wrong ? Is there a specific device that i should purchase to make both the audio input and audio output work with Surface pro 3.5 mm jack.
