There was no sound when I answered the call via Callkit.

[shuxiongwei]

Hello, my application integrates with CallKit and I'm encountering a problem: sometimes when I receive a VoIP audio call push notification, there's an occasional issue where there's no sound after answering. During my troubleshooting, I found that it might be due to a problem with the audio engine settings. The logs show that the following methods are not executed:

engineWillConnectOutput

engineWillConnectInput

Only this method is executed:

engineDidCreate

I see that the methods are executed during normal calls. How should I configure it in this situation? Are there any reliable tutorials? Thank you!

Yes we have an example app, have you tried it ?

[shuxiongwei]

Okay, I just saw it, I'll try it now.

Hello, does the code in the screenshot need any further configuration? I didn't see it in your example code.

@shuxiongwei I don't think I wrote this document, where did you find this one ? For the Swift SDK, this is not necessary.

Yes, that's where I saw it: https://github.com/livekit/client-sdk-swift#integration-with-callkit
Are you sure it's not needed?

@shuxiongwei Yes it's not required, please follow this example https://github.com/livekit-examples/swift-example-collection/tree/main/callkit
