I've got my HP Pavilion Power - 15-cb041nr hooked up to a large monitor via HDMI cable. Any time I view a video, the audio and video get out of sync, with the audio playing ahead of the video.
When streaming, it takes about 5 minutes for the video to lag enough to become distracting. I similar loss of sync streaming videos from any source I've tried (Youtube, Netflix, Amazon Prime, Comcast Xfinitiy). My internet connection seems good; video doesn't stutter or pause for buffering, it just goes out of sync with the audio.
Locally stored video takes longer to get noticably out of sync, about 20 minutes, but eventually gets just as bad.
Pausing for 30 seconds or so usually brings audio and video back into sync for a while.
I see the loss of sync using two different HDMI-connected monitors.
In limited testing, the sync issue only seems to happen when I use an external monitor. If I unplug and just use the laptop display, audio and video seem to stay synced.
FWIW, video games don't seem to have the problem.
I updated the NVIDIA GeForce GTX 1050 driver, with no improvement.
I updated the Intel HD Graphics 630 driver, with no improvement.
I checked, but no update available for the Intel , NVIDIA or Realtek audio drivers.
I bought this model specifically because of the upgraded video adaptor. I'm very disappointed in the video playback peformance. Does anyone have suggestions for how to fix this?
