The footage recorded by Live Gamer Ultra in OBS has A/V (audio & video) out of sync issue, what to do?
At OBS you can set the audio delay shift value to ensure that you get fully synchronized recorded file.
In addition, if you set the output waveout, you do not need to change any settings, the recorded file will be synchronized.
1. OBS setting “Output desktop audio (waveout)” => Audio select “Stream Engine”
2. OBS setting “capture audio only” => Audio select “HDMI (Live Gamer Ultra-Audio)”.
*If Stream Engine is selected, the file's audio will be faster, in this case if you shift the audio back for 100ms the recorded footage will be synchronized.
