How to fix no sound in some video & audio files played in Google Chrome and Opera browsers?

Question

I am trying to fix an issue where there is no sound when I play some video & audio files in both Google Chrome and Opera browsers. It seems both Google Chrome and Opera have the same issue because the same exact files have no sound in both browsers. I am wondering what is common between Opera and Chrome browser where both are experiencing the same issue.

The same files play fine in Firefox, IE 11 and Edge browsers.

Some items that play with no sound in Chrome browser & Opera
Hangouts voice messages play with no sound.
Lynda.com training videos play with no sound.

Here is a YouTube video that plays with no sound.

Most YouTube videos play fine with sound, but there are many that play with no sound. I often have to switch to another browser just to hear the video.

I would really like to fix this issue so I don't have to keep switching browsers.

Does anyone have ideas of something I should try?
Is there some codec I need to re-install or fix?

Solution

Steps that fixed my issue:

• Open Creative Audio Control Panel
• In Speaker Configuration section, change 7.1 Speakers to 2/2.1 Speakers.

This immediately fixed my issue and I did not even need to reboot. All the previous video and audio files I was having an issue with play fine now in Google Chrome & Opera browser.

Reading this Reddit post helped me solve my problem.

The reddit post link you added led me to my solution. Thank you.

the underlying problem appears to invlolve creative settings carrying over in the win10 anniversary update process (at least in my case).

Thank you, not the same solution, but my audio for my suondblaster audigy fx card under the speaker/headphones tab didn't have anything selected. I selected headphones and resaved my profile and it finally fixed the issue.

Thank you. I hope the person you want to have your babies does, in fact, have them.

For me it was in Realtek HD Audio Manager, changing 5.1 audio to stereo. Thanks
