Description JiaLi 2023-06-20 04:00:12 PDT

Hi,

We are using WebRTC to talk to each other.

We found that there will be some broken or spotty audio from time to time in speech process on iOS 16.
However there is less broken or spotty audio on iOS 15 with the same device and network.

Do you know the reason?
Could you tell me how to decrease broken or spotty audio on iOS 16?

Thanks,
JiaLi

Hi Jiali, what does speech process mean? Is it speech audio rendered through WebRTC?

If you can reproduce broken/spotty audio, would you be able to provide a repro case or a sysdiagnose?

Hi,

Thank you for your reply.

Yes, "speech process" means "speech audio rendered through WebRTC".

Recently, we added the number of packets to buffer before sending speech audio,
then the broken or spotty audio disappears (although a little delay).

It works well now.

So we won't need your help with the investigation.
Thank you very much!

I will change this issue's status to "RESOLVED".

Thanks,
JiaLi
