I use a windows 7 HP laptop, and although trying numerous inline mics, none seem to work anymore. they were working fine, and then one night after using stereo mix to show a video over skype, the mic refused to work. after thinking the mix was broken, I purchased a new one. The apple earpods were 4-pin, and worked previously, so it doesn't seem that my laptop has any problems supporting 4-pin headsets? I've been trying for months to find a way to fix it to no avail. I've tried updating the drivers, uninstalling and re-installing, replugging in, and it is in the headset/mic port that worked from before. I've looked it up, and this is my last resort. Any help would be greatly appreciated - Note, I have no idea the specifics on the make or model, as I'm not an expert on this.
