Windows 10: Windows 10 - January 2018: Videos don't play or only play audio

I've updated my computer, and since that when I try to watch a video, online or opening a file, either it shows a green rectangle instead of the video but plays the audio (Mp4 file), or the video doesn't even start (YouTube, Twitch).

Is there a known solution? Maybe changing something in the control panel.

No sound while playing audio and video files.

Hi,

I appreciate if you could answer to a few questions to narrow down to the issue.

• Which is the application that you are using to play the files?
• Did you try the same on a different player?
• Did you perform any troubleshooting steps?

As an initial troubleshooting step, I suggest you to check if the volume is set low or in mute state in Volume Mixer.

• Right click on sound icon.
• Open Volume Mixer check for the application that you are playing the files with and increase the volume and check.

If the issue still persists, I would suggest you to run “Playing audio” troubleshooter to diagnose and fix the issue.

Follow these Steps to run Playing Audio Troubleshooter in Windows 10.

1. Type troubleshooting in the search bar.

2. Select Troubleshooting.

3. Select View all on the top left corner.

Activate Sound in Video by playing audio first

Hey guys,

I bought a Lenovo Yoga 910 recently.

I'm happy with the design and build quality.

But I'm experiencing an annoying issue with video playing.

Here's the situation:

If I play videos, whether it's online like YouTube or local file like movies downloaded,

There would be no sound from the video at all while the sound from the system work normally.

Here's what I've been doing to "activate" the sound of the video - I play an audio file!

Even for just 1 second, I can switch back to the video and the sound would work right!

It's like, I need to play audio first to activate the sound playing then I can play video.

Once I play the audio, I can play any video with normal sound until the next time I turn on the laptop.

Notes:

1. I don' t think it's the driver issue. If the hardware is not working right with driver correctly installed,

the system sound and the audio shouldn't play at all. In a word, it should be a dumb computer

2. It's not about the app setting. It happens to 4 different video apps: Movie&TV, Windows Media Player, KMplayer, Thunder Video Player. It also happens to YouTube and other online videos.

3. The video files are not corrupted or packed without sound because after playing the audio all of them are playing right.

Does anyone have any idea what cause the problem and how to fix it?

P.S. Lenovo Tech support suggested that I should reset the BIOS and see what happen.

Later I will try reinstall the driver and reset the BIOS then I will update the result.
