[~filmaj]yes I have a signed Apache ICLA. I got an e-mail from Craig L Russ=

So please ask the Cordova PMC (because I don't know who this is:-)

> I get =E2=80=9CFailed to initialize AVAudioRecorder: (null)=E2=80=9D in t=
he error callback of the startRecordingAudio() exec API.
> I see that the AVAudioPlayer settings in CDVAudio.m are
> {code}
> NSDictionary *audioSettings =3D @{AVFormatIDKey: @(kAudioFormatMPEG4AAC),
>                                             AVSampleRateKey: @(44100),
>                                             AVNumberOfChannelsKey: @(1),
>                                             AVEncoderAudioQualityKey: @(A=
VAudioQualityMedium)
>                                             };
> {code}
> This is IMHO the reason it doesn=E2=80=99t work. Either one uses the .m4a=
 extension with {{kAudioFormatMPEG4AAC}} or
> .wav with the {{kAudioFormatLinearPCM}} key (the IOS docs are very unclea=
r about which file extensions are actually supported)
> The plugin enforces =E2=80=9Cwav=E2=80=9D but the settings enforce the MP=
EG4AAC encoder.
> Using the attached simple patch and using .m4a at the JS side solves the =
problem and records on my iPod touch IOS 8.x.
> I stumbled also across https://github.com/remoorejr/cordova-plugin-media-=
with-compression where the exchange wav->m4a is done too.
> Strangely I can=E2=80=99t find much problems reported on stackoverflow, b=
ut this one seems to cover it
> http://stackoverflow.com/questions/12244111/failed-to-initialize-avaudior=
ecorder-null
> The last poster seem to indicate that the problem sneaked in in IOS 8 (pr=
eviously it was probably possible to record to a .wav file but with AAC con=
tent).
> Looking at the recordAudio() test for the plugin in tests/tests.js I can=
=E2=80=99t see that potential errors are actually causing the test to fail:=
 they are just logged with console.log , so this may explain why the proble=
m has not been detected by the tests.
