Today, my set of external speakers for my laptop (HP ENVY m6) stopped working suddenly after I unplugged them to move the laptop and then plugged them back in.
The speakers will play audio from other devices (so they're not defective), and now I can't hear audio from anything else plugged into that jack, like headphones.
I have a dual boot of Windows 8.1 and Ubuntu 14.04 on this laptop, and the jack doesn't work on either OS.
Is the jack faulty? If so, what can I do to get external audio working again?
