On an Iphone (IOS15), We cannot hear others using the Wechat and Safria browsers

Local and remote microphones and cameras are working fine. I can be heard remotely, but I (IOS15) can’t hear the other person.
Occasionally, very rarely, I can hear it. Infinitesimal case.

I tried VP8, VP9, and 264, all with the same result.

This was only available in recent versions of Docker, but I found that going back to previous versions, there was no sound either. So I feel like it’s IOS. Ask the Jitsi if there is a way around this problem

We have similiar issue, users from desktop can be heard, but not from iphones with iOS 15.

In the current version, we still have this problem.
The problem stems from the need to trigger a sound play first. It’s been solved.

Have you tried enabling the welcome page?
