Audio out of sync

Question

When streaming by RTMP, watching WebRTC, under some load on server audio can go out of sync for viewers. In worst case scenarios it can be up to a second. What can that be caused by?  HLS is fine at the same time.

Also, some recordings of live streams have out of sync audio. Any way to prevent that from happening?

I have some recordings that have out-of sync audio, may be caused by video and audio. 
Most recordings are ok, but delays are caused by WebRTC server or client overload, possibly.

Hi Mark,

Sorry for my late response. Can you try recording the stream to check the recording is not out of sync?

Hi Asim,
We have sync issues only on mp4 recorded videos, the audio have 3 seconds delay, on live we don't have this issue. 
The problem still on recorded mp4.
Thanks in advance

Hi Mike Aguilar,

how do you publish the streams? do you use WebRTC or RTMP? If RTMP can you send the settings you use?

Best Regards,
Can
