Long delays in audio on a call are typically due to latency in the connection itself. There are many things that can cause this issue.
Delayed audio can be caused by many different factors. We put together this guide to walk through the possible reasons you're experiencing delayed call audio:
The most common reason for delayed audio is jitter. Jitter indicates a connection issue occurred on the call. Jitter affects your call's packets of audio data transmitted to-and-from. This can result in packet loss, which can cause latency issues. Thankfully, there are a few steps that may alleviate these issues.
Your internet connection
While your internet connection may have lightning-fast speeds most of the time, if your speeds are temporarily throttled, you may experience call quality issues. Here are some steps that may resolve jitter:
If you're using WiFi, reset your router
Switch to a different internet source (e.g. WiFi to data or vice versa)
While the strength of the internet is the most likely culprit, it's also possible that the issue is due to the device itself. Here are a few things you can do on your device to help improve your call quality:
If you're running any CPU intensive programs in the background, try closing those programs
Try switching between mobile and desktop (e.g. you may find that your laptop works better with a weaker internet connection than your mobile)
Try completely powering down then restarting your device
While these steps typically solve the problem, if they do not, then we'll need to dig into them a little more.
If this issue is only occurring with one contact, it's likely that the issue is coming from their end.
