I have a Dell Inspiron N5050 and for some reason the audio stopped working properly. When I plug in headphones it should only play through headphones but instead it plays through BOTH headphones and speakers. How can I turn off the speaker so it just plays through headphones when headphones are plugged in?
Some systems have an Audio Control Panel that allows the option of having the speakers on when you plug in headphones, or to not have speakers on. Check the Control Panel/Hardware and Sound to see if you have this and the option.
For example, I have RealTek audio and in my Realtek HD Audio Manager, I have the option for how I want the headphone jack to operate.
You say you uninstalled and reinstalled the audio drivers, . Non-Vendor drivers in many cases may not work or work correctly.
install dell recommended drivers only....
Hello. There are a few things you can try with the audio driver. These are in no particular order.
> Perform a simple re-installation of your IDT audio driver. If there is a mis-configuration of the driver settings, doing this will correct it.
> Or download and install a fresh copy of your IDT audio driver from the Inspiron N5050 support page. If the files of your audio driver have become corrupted, doing this will fix it plus correct any misconfiguration as in the step above. Be sure to select your operating system in the menu before downloading the audio driver.
> If the issue still persists after the above steps, switch from the IDT audio driver to the Windows native audio driver.
1. Open the Device Manager (type devmgmt.msc in the search box and hit Enter).
2. Expand the "Sound, video & game controllers" and right click on "IDT High Definition Audio Codec".
3. Select to "Update Driver Software".
4. Click on "Browse my computer for driver software".
5. Click "Let me pick from a list of drivers on my computer".
6. Put a check in the box "Show compatible hardware" if not already checked.
7. In the list of devices, click "High Definition Audio" (the native driver).
8. Click "Next".
9. On the Update Driver Warning box, click "Yes" (install the driver).
10. Restart the laptop if prompted. If not prompted, then no need to restart.
[To get back to the IDT driver, do it again but reverse the names in steps 1 and 6.]
If the issue persists even with the native audio driver then it is probably a hardware failure.
Struggled with the same problem. Then noticed when I muted the "line-in mic" that the headphones also muted.
Fixed it by disabling the line-in mic.
How to: right click on the speakers icon (bottom right corner). Select "Recording Devices". Right click "Microphone/Line In" and select "disable".
