No Output on right channel from Realtek High Def Audio

[JohnH12]

Until recently the sound output worked normally, i.e. separate left and right sound channels. Something has caused the right channel to disappear. The sound card now functions like a mono, single channel device. The most recent change to the system was the Windows 10 feature update. I've tried all the built in diagnostics, the HP diagnostic tool and searching for updated drivers. I've just about reached the limit of my abilities and would appreciate some advice or alternative approaches.

@JohnH12, Welcome to the HP Support Community!

Let’s try the steps mentioned below to change your audio output to stereo.

• From the bottom-right corner, click on the Speaker icon > right-click on “Sounds” icon and choose “Playback devices” option.
• Select your headphones/speakers. Click the "Configure" button, which pulls up the Speaker Setup dialog box.
• Select "Stereo" from the "Audio Channels" menu and test the current settings.
• Also, click on “Properties” after selecting the “Speakers / Headphones” and navigate to “Advanced” tab.
• Try changing the “Default format” to appropriate studio qualities if it makes it better.
• If the issue persists, proceed to the next step.

Install updates using HP Support Assistant

1. In the search box, type and open HP Support Assistant. 
2. Check for updates.

Hi Kumar,

Thanks for the update. I completed the initial steps, When you test the individual speakers the right hand speaker graphic acts as though sound should be coming out, but nothing is heard. 

I moved onto the support assistant, and it reports no updates are available and that no bios updates are required.

Regards

John

Have you tried connecting these speakers to a different PC and check if it works?

Let us also perform a test on the sound card. 

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press Esc repeatedly, about once every second.
3. When the menu appears, press the F2 key.
4. On the main menu, click Component Tests > Audio.

Share the results. Keep me posted.

Hi Kumar,

I was following you suggestion to try the speakers on another PC when I noticed that the left speaker had been moved and the connection to the right speaker had been dislodged. Its all a bit embarrassing really. 

The Audio test was fine, except there was no sound from the right speaker, which on reflection was logical.

Still, all working fine now,
