I recently got a new laptop, a fine piece of art actually, rather than a laptop, a Lenovo Yoga. It came with Windows 8 from the shop so I went and updated Windows 8 to Windows 8.1. After the update when playing videos, .avi and .mp4 from my phone, there is no audio. I installed K-Lite Codec Pack to be sure I have all the codecs, but no help from there.
Here’s how I solved no audio in Lenovo Yoga Windows 8.1 video playback:
1. Click on system tray sound icon
2. Select “Playback devices”
Now a message appeared, saying there is a problem with audio enhancements and asked whether I would like to Disable driver enhancements for the device.
3. I clicked “Yes”, then clicked “OK” on the following screen.
Voila! Playing a video with sound again (went for a Formula 3 car driving experience and sounds were much needed for me) 🙂
Hope this helps!
