React-native-sound: [Xcode10] ValidateRequiredFields Unknown selected data source for Port Speaker

[ya-watanabe]

Hi,

After upgrading xcode version, there are following log message every seconds.

 2018-09-20 11:58:09.622656+0400 MyApp[1027:137400] [avas] AVAudioSessionPortImpl.mm:56:ValidateRequiredFields: Unknown selected data source for Port Speaker (type: Speaker)

Does any one know the solutions? Thanks

@ya-watanabe Getting the same issue after upgrading xcode as well BUT it is only happening on iPhone XS models with iOS 12, not on any previous iPhone with older iOS versions. Not entirely sure if it is hardware induced (stereo speaker setup on XS models, perhaps?) or iOS 12 software level requirements (introduced recently?).

I saw it on my iPhone6 iOS 12 also。https://forums.developer.apple.com/thread/108785。
They say it has no way to finish off!

I have the same log message, and it is after I've added AdMob to my app.

@Starsky89 I'm experiencing the same case. After adding Admob, it appears.
