    Connect a line level audio feed to laptop headset connector


    Am I right in thinking there is a microphone input available on the headset 3.5mm jack on a laptop?

    If so, I would like to feed in a line level signal which I understand is at a much higher level, so some adjustment would be needed.

    This link How To "Convert" A Laptop Microphone Port To Line In - YouTube suggests its possible but I am unconvinced.

    Also do I need a TRRS plug to go into the laptop in order to access the mic input?

    " Am I right in thinking there is a microphone input available on the headset 3.5mm jack on a laptop?"

    If it is a Combo jack, yes, some Laptops have a separate mic input 3.5 mm jack.

    There are potentially 2 types of TRRS Combo jack used by different manufacturers. OMTP and CTIA.

    The Mic input may detect the higher level of a line input and adjust accordingly. You would certainly put Mic Boost to zero and lower the Volume slider.

    That video is a bit confused, the Mic input is mono as it would be for a Line input as well. i.e. L and R would be the same.
    So if you wanted stereo line input it would not do. You would have to add a USB dongle thingy.
