Hi,
Thought I would start a new thread as noone seemed to post a definitive answer to the issue the poster was having regarding their headphones. I was having a similar problem while trying to watch Youtube, the speakers on my HP 625 were playing the sound even though I had my headphones plugged in. Not quite sure how I resolved it for myself, but when I opened up the IDT audio control panel within the 'hardware and sound' section of windows control panel, the speakers needed to be set to both default communication and default playback device. As well as making sure within this control panel that the headphones were selected for the appropriate jack, this solved the problem for me. I'm not sure if any of this stuff was different before I opened up the IDT control panel since I'd never opened it up before, but like I say the problem was solved so hopefully this may be of some help to anyone having the same problem. :)
