I recently purchased a ThinkPad P50 that came with Windows 10 pre-installed. The video and audio work fine. When streaming videos from the internet, however, the audio slowly becomes out of sync with the video. I have tested this with YouTube, Netflix, and Amazon Prime in the latest versions of Chrome, Internet Explorer, Edge, and FireFox.
Things I have tried:
- Recently updated to Windows 10 Creators Edition and ran Windows Update
- Updated BIOS to latest version
- Set the graphics mode to "Discrete graphics" within BIOS
- Uninstalled / Reinstalled audio and video drivers
- Updated to latest version of NVidia Video Drivers
- Updated to latest version of RealTek Audio Drivers
- Disabled Enhancements in audio applet
- Turned off Dolby Audio
- Turned off Exclusive Mode (Allow applications to take exclusive control of this device)
- Tried different audio formats (41000Hz and 48000Hz in both 16 and 24 bit)
- Ran Windows Audio Troubleshooter
- Ran Lenovo diagnostics on Audio, Video, and Wifi
- Ran System File Checker tool to repair missing or corrupted system files
- Posted to Lenovo forums but did not receive an answer that worked
We have several other computers in the house and they do not have any audio / video sync issues with Windows 10. Any help with this issue would be appreciated.
