Hey guys, first let me say that I'm such a novice with computers I'm not entirely sure if this is the right section to post this question in but I think it is. Anyways, I own a HP Pavilion dm4 Notebook PC, 64 bit operating stemmed with Intel and windows seven. I'm not entirely sure what the sound card is or if that matters for this question but it's audio is built by beatsaudio. So I've had this computer for a few months now and it's been running great, including and especially the audio since I listen to a lot of music. But all the sudden when I plug my headphones into the headphone jack on the computer the sound is still coming out from the speakers. When I put the headphones in the headphone jack I still hear that brief staticy/ electricity sound that you do and some white noise emits from the headphones but all of the audio is coming out from the speakers. I checked and the headphone setting is not muted and under the sound settings on the control panel the headphone jack is turned on but still no sound. I've never had this problem before and I don't know what's causing it. Any help would be greatly appreciated.
