I think the problem is only with the speaker amplifiers, not the sound adapter itself. So I think it's better to use Bluetooth speakers & headphones than to risk creating new problems by opening the laptop again. Jack E/NJ

>>>speakers are working fine but no sound >>>

What ACER model, number and current WinVer? Jack E/NJ

AdityaShinde

It's Acer aspire ES1 521 237Q

If Device Manager shows no issues and the volume controls are not muted in any way, then you must again disassemble the machine to re-seat the mainboard connector for the blue, white, brown & black wires coming from the left-side speaker. This connector was probably jarred loose. There should be a piece of tape holding the wires to the case so the connector stays put. If the tape is loose, you can use ordinary transparent or duct tape to secure it again. Jack E/NJ

Not the tape!!! Did you re-seat the SPEAKER CONNECTOR on the mainboard? The small red arrow in the picture points to this small SPEAKER CONNECTOR. Jack E/NJ

AdityaShinde

Yes sir I removed both speakers with battery and put it again

Are you certain that the speakers were working immediately before you opened the laptop? If yes, try turning them back on in the Fn+F8 toggle key combination. Jack E/NJ

AdityaShinde

No nothing worked for me ☹️ yea I have installed Windows 8.1 now but still no sound i brought my friend's Bluetooth headphones and connect them to laptop and they are working so why audio jack and speakers not giving any sound soo weird

JackE

Did you try the Fn+F8 toggle key combination to try to turn the speakers on? Jack E/NJ

AdityaShinde

Yes sir that mite button (f8) i have tried

AdityaShinde

Sir I have reinstall windows 10 first then installed Windows 8.1 so I don't think it's software issue

AdityaShinde

Hello JackE sir I think problem is something else when I was checking playback settings of SOUND i put my headphones in ear and started testing more sounds then I observed some sound like BEEP or some little sound coming from my headphones i don't understand what's happening (Bluetooth headphones working fine but wired headphones not)

JackE

>>>Yes sir that mite button (f8) i have tried >>>

No! To unmute, you must also press the Fn key at the same time you press the F8 key. Jack E/NJ

AdityaShinde

But sir I have tried that mute/invite button i have reinstalled my OS 2 times and 3rd time I changed it to windows 8.1 but still 😞

JackE

Please. You must push two (2) buttons. The FN button PLUS the F8 button. Did you push BOTH buttons? Jack E/NJ

AdityaShinde

Yes sir I have pressed both i already know my laptop 😃 but I installed new OS so how can it be a Software issue

JackE

Thank you. I must confirm that you pushed two buttons so that ***we both*** can come to the same conclusion of a hardware problem.

Open Device Manager. Click on sound, etc adapters. What sound adapter is listed? Jack E/NJ
