Missing audio when headphones is plugged out in iPad2/iOS9

[alexiss03]

Hi,

I am encountering missing audio when headphones is plugged out during an ongoing video call. To replicate, connect two devices of which one was iOS 9 running on an iPad2. Then, connect the headphones to the iPad 2. The audio is successfully rerouted to the headphones but when the headphones is plugged out, the audio is not redirected to the device's built-in speaker. I have replicated the same issue with your demo app. I have also inspected the routing of the AVAudioSession and it gives the AVAudioSessionRouteChangeReasonNoSuitableRouteForCategory which probably caused the error. Hoping for your immediate response. Thanks!

Cheers,
Lexi

Hi @alexiss03,

Thank you for the report, we will try to reproduce and get back to you. Do you use a particular TVIAudioOutput setting when the AVAudioSessionRouteChangeReasonNoSuitableRouteForCategory occurs? Can you share logs of the time leading up to the error?

@ptankTwilio this looks pretty similar to twilio/video-quickstart-ios#93, assigning it to you.

Best,
Chris Eagleston

Hi Chris,

I've tried using TVIAudioOutputVideoChatDefault and TVIAudioOutputVideoChatSpeaker for the TVAudioOutput. Both produced the same scenario.

Thanks,
Lexi

@alexiss03 We are able to reproduce this problem on iPad 2 running iOS 9.3.5. At present we are working on media APIs and GA release, so we won't have this fixed in beta15. We are planning to fix this immediately after GA. I will let you know when the defect is fixed. Thanks.
