Out of sync video and audio


New Member
Ever since some driver/firmware update in the last quarter of 2017 (I cannot pinpoint which), I noticed that my SP4 tends to playback videos with audio out of sync (i.e. audio happens before the video) whenever I pull video data via the wireless network adapter.

It doesn't matter whether I am playing a video file off my NAS or other home computers, or streaming from Youtube. Eventually the audio will sound off earlier than the video. If I connect via my USB-Ethernet adapter, then video and audio stay in sync.

Has anybody else experience such odd behaviour? This wasn't a problem I noticed for the initial year of usage.
