I don't know what has happened to my Windows 7, but I am not able to hear any volume until I wear earphones. The hearing device is Speaker. Another thing is that when I don't wear earphones and open anything like YouTube then it shows like this
If I am not wrong this means that the sound is getting produced, but I am not able to hear it still. I have to wear an earphone to hear any sound from the laptop however the earphone is little damaged now, so I wanted to hear sound from the speaker only. The speaker of my computer is in-built. I have set the voice too at good level that I can hear.
So as you can see the amount of sound coming has been set high by me. Another thing is that like when I wear earphones and choose the sound giving speaker as Speakers/HP the sound can be heard without earphone too but sometimes the sound is loud sometimes mere however this voice is doesn't come now as my earphone are damaged. I don't want to buy a new earphone as already many earphones have been damaged by me. Maybe there might be some small mistake by me like once I was getting disturbed because of text cursor scrolling me down but then I realized that I had turned on the caret browsing so similarly maybe there might be a small mistake here too.
As you can see these all are speakers of my computer and I am not able to hear any until I wear a well working earphone. I also tried running the troubleshoot but it showed that there is no error the device is working fine. I tried uninstalling and then again installing the drivers but in vain.
These are the speakers device present in my device manager. And from the first image you can see that my sound is not muted.
Even I have tried also tried updating my BIOS system but in vain. So please can anyone help me resolve this problem? Let me specify you that this is some software problem according to me because if speakers weren't working then how would wearing working earphones made the speaker work but as soon as you plug off the earphones the speakers don't work. Pls don't suggest to buy me a speaker like These as I frequently take my laptop from one place to another so working with carrying speakers from one place to another would be quite difficult for me. Plus using external speakers at work doesn't seem a good idea. My laptop also gets connected to a Bluetooth but Bluetooth doesn't give any voice however the Bluetooth gives voice with other laptops and devices. So pls suggest me how to resolve this software issues? Or do you still think it is a hardware issue? I know this is a duplicate question like https://superuser.com/questions/1621106/not-able-to-receive-sound-from-my-laptop-unless-wearing-earphone but in that no one was answering and having less number of reputation I could not risk my reputation by starting bounties so that is why I asked a duplicate question. Apologies for grammar mistakes
