HP ENVY All-in-One - 27-b170na

I fixed this problem once before by uninstalling a driver. Unfortuantley I didn't take anote of it.  After an upgrade (I assume) the problem has returned and can't be fixed even with a jacked-in microphone (which did fix it once before after the problem first occurred).  Every single audio setting (including the B&O ones) or troubleshooting says the mic is muted, and it unable to be unmuted. Please tell me how I can fix this again.

 

Thanks

Hi @LL2022xyz.

 

Welcome to the HP Support Community. 

 

I'd like to help!

 

Follow the advanced troubleshooting steps to resolve audio issues on your desktop computer.

 

Understand desktop sound devices and connections

Most desktop computers do not come with built-in speakers. You must connect headphones or speakers to the ports on the front or rear of the computer to hear audio.

NOTE:

If your computer came with a discrete graphics card, there might be a plastic cover blocking the HDMI port attached to the system board. Most computers can use video from the graphics card or the system board, but not both at the same time. If you remove the plastic cover and connect a monitor to the port, video and sound cannot work unless you remove the graphics card.

Use the following graphics to identify the ports for connecting various audio devices:

(4)

(5)

(6)

Line-in

Check your headphones

Check the computer sound from your headphones.

 

Types of headphones

HP computers support three types of headphone connectors. One supports only sound to the headphones, while the other two support both sound to the headphones and microphone. Symbols mark each type of connector.

Connectors on the computer marked with a USB icon support both sound and microphone.

Example of a USB cable connector

Connectors on the computer marked with a headset-only icon support output sound only and work with either a standard three-pin headphone or a four-pin headphone for sound.

Standard three-pin jack

Connectors on the computer marked with a headset-with-a-microphone icon support sound and a microphone when used with a headset with a four-pin plug and a microphone.

Four-pin jack

Test the computer sound with headphones

To hear sound, the three-pin plug and four-pin plug can be used with either a headphone or headset connector. Using a four-pin plug that is capable of supporting a microphone in a three-pin connector allows sound to be heard, but the microphone does not work because the computer's three-pin connector does not support a microphone.

Find and unplug all audio cables from the rear of the computer.

Plug headphones directly into the speaker out connector on the rear of the computer. The speaker out connector might have a symbol of a speaker or a circle with an arrow pointing out, or it might be labeled as OUT.

Line-in or Rear speaker Out

In Windows, right-click the speaker icon in the taskbar, and then select Open Volume mixer.

Move the volume control slider to test for sound. Each time you click the master volume slide bar, you should hear a chime through the headphones.

If you hear sound through the headphones, the sound hardware on the computer is working, and the issue is probably related to the speakers or speaker cables. Disconnect the headphones and reconnect the speakers.

When done, test again for sound using the previos steps with the volume control slider. If sound still does not work correctly after reconnecting the speakers, try replacing the speaker cable (if possible) and test again.

If you cannot hear sound through the headphones, make sure that you are plugging the headphones into the correct connector, and try again. If there is still no sound, go to Set the default speakers and test the audio.

 

Click here for the remaining steps and see how it goes.
