I'm using a lenovo thinkpad e440 laptop (I chose the discrete graphics card variation if that makes a difference to the audio input) and currently all I can use is the internal mic which is 'below average' in terms of quality. I looked around the laptops outside and only found a headphones slot, I tried putting my mic into that slot but had no success. Can my laptop use an external mic as of now? if it can't, is there an adapter or something I can get?
