It's a laptop (dual booting Win10[recently upgraded from win7 64bit] and Elementary OS Freya)
It's nothing to do with hardware issues
Earphones worked fine on my Elementary OS so my audio jack is definitely not broken or anything like that. Earphones work on my phone as well so i'm quite positive it's to do with windows 10 only.
No sound coming out of earphones
There's no sound coming out of the earphones, and I'm sure it's nothing to do with them because they work fine when I plug them into my phone. Also, I've tried another pair of earphones which resulted the same. However, the sound works perfectly without the earphones plugged into my laptop, the speakers are fine.
unsure if it's to do with drivers
I've tried uninstalling the Realtek HD audio drivers, reinstalling and nothing works.
However, I have Windows 10 but could only find drivers for Windows 7/8
settings
I've googled a bit and most would suggest something like checking the playback devices but the only one on my list is 'Speakers'.
Realtek detected my earphones
When I plug in my earphones, Realtek detected them and even popped up the notification saying 'you just plugged a device into the audio jack'
