No sound on my laptop internal speakers

I've been facing sound problem on my dell inspiron laptop since yesterday. It only plays sound when I plug in my headphone. I have 64-bit windows 7 installed.

I've already checked in sound, video and controllers driver's status which is showing "This device is working properly.". I tried restart, but that also not worked.

Does anyone know how can I solve this problem?

Solution 1:

This happened to my laptop few years ago and It still exist. What has happened to your laptop is that the headphone pin has broken [or hopefully just stuck] and when you unplug your headphones, the computer still thinks there's a headphone connected.

You should replace the headphone pin (It's quite cheap) to fix the issue completely.

There are several "hacks" to temporary/luckily get it to work:

2. You can edit registry settings to force disable headphone jack and output the sound through speaker.

   Press Start > Run > Type regedit > Choose My Computer > from menu select edit > find > Search for "ForceDisableJD" and press find. > once found change the value from 0 to 1. > restart

Please note that the above solution will disable your headphone jack and you'll have to change the value back to 0 in order to use it again. Good luck!

Solution 2:

I had a similar problem with my Macbook once, I solved it by plugging and unplugging the headphones multiple times, fairly rapidly (Of course, be careful not to break the socket or plug). There's a sensor inside which can get stuck, if it thinks there are headphones plugged in at all times then you will never get sound from your speakers.

It's not a particularly technical answer, but I think it might well be the solution you're looking for.
