I have these cool earphones, and the first time I got them, I plugged them into my PC. Worked perfectly, except they were called 'speakers' 2 or 3 months later, I take them out and plug them into my samsung tab2 tablet. They worked perfectly. I plug them into my PC again after a couple of hours. I hear them crackle a little, which is normal when I turn them and plug them in cause they're a little bit broken, but Yeah. I plugged them in and heard them crackle, so I KNOW my PC can receive sound through them. Buty... I play youtube. Nothing. I play VLC media player, nothing. I go into playback devices, and there's now speakers and 'headphones' I've tried settings headphones and speakers to default but no luck. Normal HDMI sound still works perfectly. I've heard all good things about this website, so I hope you can help.
