Hardware: PC with Intel Core i7-8550U 64 Bit CPU 1,8GHz, 16 GB RAM I'm using DaVinci Resolve 15.2.2.007 with Windows 10 Home Version 1803 Build 17134.523. Release video I/O hardware when not in focus: not enabledĮnable Fairlight Audio Accelerator: not enabledĭevice: Speakers (Realtek High Definition Audio) Under 'DaVinci Resolve - Preferences - Video and Audio I/O' the settings are:įor capture and playback use: none (default setting) I changed the sound card settings for the speakers from 24 bit to 16 bit 44.100 Hz, with no difference.ĭoes anyone have an idea what might help to get the sound within DaVinci Resolve? I already downloaded the k-lite_codec_pack_1465_basic.exe and installed it (with a restart of the computer), but that didn't help. It's just the mp4 files that came from Facebook which have no sound only in video editing programs.

In the timeline the audio track shows no signal vizualization at all.Īll other mp4 files I tried (from different sources like YouTube, television media libraries or own camera recordings) work properly with sound. Using three online download and converting service websites I received the mp4 files from these three sources.Īll mp4 files show the same problem: They have sound in Facebook and within the VLC audio player and the windows media player, but not within DaVinci Resolve, and not in a different video editing program I tested (Magix video deluxe). I downloaded two videos of a Facebook live stream (that are saved in Facebook) from an event I hosted.
