problem with audio codecs

[joselcv]

Flutter Sound Version :

• Flutter 3.13.9 • channel stable •?

• Important: Result of the command : flutter pub deps | grep flutter_sound
  ├── flutter_sound 9.2.13
  │ ├── flutter_sound_platform_interface 9.2.13
  │ ├── flutter_sound_web 9.2.13
  │ │ ├── flutter_sound_platform_interface...

Severity

• Crash ?

---

Platforms you faced the error

• iOS
• Real device iphone 11 (ios 17.0.3)

---

Describe the bug
When I try to record audio with:
FlutterSoundRecorder recordAudio = FlutterSoundRecorder();

playFunction()async{
await recordAudio.openRecorder();
await recordAudio.startRecorder(toFile: '${folder.path}/myFile');
}

and do not specify the codec parameter, it returns an apparently empty .bin file, if I try to specify any of the codec (Codec.aacMP4,
Codec.pcm8) etc. an error appears saying that these codecs are not compatible with the platform

Valid codecs can be foud here

Do you run on Web Dart or native iOS?

[joselcv]

I'm running it on iOS, of the codecs it supports, none of them work bro 😕😰

[radvansky-tomas]

Same here, I am trying to run startPlayerFromStream and every combination of codecs crash the simulator. And in xcode it says that there is invalid format/number of channels.

[UmairSaqibBhutta]

same issue

same issue

[github-actions]

This issue is stale because it has been open 365 days with no activity. Leave a comment or this will be closed in 7 days.

[etekumoses]

This issue is still coming up not sure why

[RitchieP]

Yes, the issue persists as of now. @joselcv do you have a workaround this?

[Larpoux]

@RitchieP , @joselcv

I think that there is a big problem with Play from Stream and Record to Stream on iOS.
It used to work fine, but it doesn’t anymore in the last versions.

This is really bad because I think Sound with Streams is a very important feature.
I spent several days fighting to debug this issue, but was not successful.
I don’t have time to work further on Flutter Sound maintenance and someone one else should work on this issue.

I am very sorry for that.

[RitchieP]

Hmmm, guess the problem also exists in Android. I forgot to mention I faced a similar issue in Android
