Okay, so I am having an annoying problem involving the sound from my HP Pavilion dv7-4087cl laptop. Yesterday, I noticed this happened after I had gotten a third-party replacement laptop battery charger for it. That is probably unrelated information for this particular problem, but I mentioned it just in case.
So anyways, I turned my computer on and put my external computer speakers in the headphone jack to listen to audio from a video. I got no sound coming from the external speakers, but from the computer's built-in speakers instead. I then tried plugging my headphones in to see if it would give a different result, but it did not. Just in case, I plugged the external speakers to my phone and found that they played without a problem. So then I checked to see if my headphones were hooked up to the computer. They were. I even performed a sound test on them which fed sound straight into the headphones as normal. But when trying to use my computer's applications for sound, I would only get sound coming from the computer's built-in speakers.
I saw tips on restarting and thought that would it fix the problem. Good news and bad news for this:
Good: Sound fed through the headphone jack again, when testing it using my headphones and external speakers
Bad News: W I simply closed the computer, which simply puts it on standby/off position, last night. I opened up the laptop tonight just now and found that it has returned to this faulty situation.
I need help getting my computer sound to work consistently again, without any forms of interference or the worry of it going out on me again. I looked on the web about a problem like this, but I saw mixed results and situations not quite like mine. Here, I feel that I can get that specific attention to this particular problem. Hope to here from someone soon. Thanks.
**update** Restarting seems to offset or resolve the problem. But I used to be able to simply close my computer shut to turn it off and be able to lift it open and resume from standby mode of what I was doing without the sound not losing its feed to the headphone jack.
**update 2** Right now when coming off of standby mode, the sound is feeding through the headphone jack and into both the external speakers and the headphones. It has done so successfully the last 2 times today. I will keep a watch over how it does ito the next day.
