Solved Lenovo g50 no sound both speakers and earphone

[Ngzek]

Lenovo G50 sound lost suddenly. Both build in speakers also ear phones are not working. There is no exclamation mark with the sound device in device manager. And i tried to update driver from device manager but said I am having the latest driver. I disabled sound driver and enabled but still not working. I tried to reinstall the sound driver but I got a notification that sound driver cannot install because device not found. Please help me friends

Download and reinstall the Intel chipset driver. Then try the Conexant sound driver

fireberd I have reinstalled intel chipset driver but still getting installation failed: device not found notification when installing conexant sound driver for G50-80, windows 8.1 64bit.

Check the BIOS in case the sound accidentally got disabled. If its disabled in the BIOS, Windows will not find it.
Otherwise I would suspect a hardware failure.

 

[Ngzek]

Okay let me check BIOS settings

In BIOS I find only power beep options disable/enable. Still getting no beep no sound after enabling this. If it is hardware problems should i repair motherboard or buy a new usb sound card? please share. Thank you fireberd

One other thing to try. Uninstall the Conexant sound AND uninstall the driver (in the Device Manager). Then restart the PC and Windows should detect and install the generic, basic function, High Definition Audio Codec (driver) if it can find it. If that works, then the hardware is OK and there is another problem.

After you do that, post a screenshot of the Device Manager, Sound.... Section.

Here is my Sound section, for example. (Disregard the Tranzport entries, that if for my recording studio) The AMD High Definition Audio Device is for an AMD Video Card HDMI audio. The Realtek in my case is my sound "card".

Restarted pc device manager image after uninstall all the sound drivers . Still getting no sound

 

[fireberd]

Windows installed the High Definition Audio drivers, so the sound "card" is being recognized by Windows.
Go to the Sound Panel and verify "Speakers" are set as the default audio playback device.

I see an Unknown Device under Bluetooth. I wonder if that is causing the problem. Disable the Bluetooth device (unknown device) and see if that allows speaker sound.

Here is my Sound, Playback Panel.

I see a post on the Windows 7 forum with exact same screenshot as what you have posted????

Speakers are setting as default playback device and i 've disabled unknown bluetooth device but getting same result. also why can't we install conexant audio driver here in this laptop?

 

[Ngzek]

I am happy to know that sound card is detecting by windows. I think sound card and its circuit are working

 

[fireberd]

You should be able to install the Conexant driver from Lenovo (don't try other drivers). I linked you earlier to the drivers.

Installing the High Definition Audio was a test to see if the sound hardware is working, and it is. If the High Definition Audio did not install then I would say there is a hardware problem.

Okay I will try again conexant driver from the above link you show me.

 

[Ngzek]

In the Lenovo support page "severity" option when "recommended" is selected no driver is available for Lenovo G50-80 but when selected "optional", one conexant driver appear which give device not found error while installing.

 

[fireberd]

That appears to be the correct driver. I have to leave for a music playing job (I'm a musician) but I'll try to help more in the morning.

 

[Ngzek]

You are right conexant driver successfully installed but no sound again. Thank you very much fireberd. Have a great day

 

[fireberd]

Have you tried the headphones since reinstalling the Conexant driver?

 

[Ngzek]

Yes I have tried with some headphones and also system restored to oldest possible date

 

[fireberd]

My next thought (guess) is that something has happened to the headphone jack to cause no speaker or headphone sound. In many PC's the headphone jack controls speaker sound by an extra contact. This gets to the hardware inside, many PC's have a "Daughter" board with the I/O jacks on them. If there is a bad connection between the daughter board and the main motherboard that can cause no sound. It may not be your problem but one to consider. However, that involves disassembling the laptop to access the hardware, something you may not want to do. Best option, now, is to take it to a qualified laptop PC repair shop and have them check it. You will have to pay for the service but it will find out what the problem is (and maybe fix it).

On the other hand, since this is a discontinued "entry level" laptop with Win 8, it may be time for a new PC with Win 10. The cost to repair may exceed its worth.
