expo-av: [Error: Prepare encountered an error: recorder not provided.]

Summary

At first, it works so I could record but after that, I could not record again because of the below error.

[Error: Prepare encountered an error: recorder not provided.]

Thank you.

Managed or bare workflow? If you have ios/ or android/ directories in your project, the answer is bare!

SDK Version (managed workflow only)

Environment

I tested it on iphone 6s 15.4.1.

Reproducible demo

This is my code base.

const startRecording = async () => {
    try {
      await Audio.requestPermissionsAsync();
      await Audio.setAudioModeAsync({
        allowsRecordingIOS: true,
        playsInSilentModeIOS: true,
        staysActiveInBackground: false,
      });

      const { recording, status } = await Audio.Recording.createAsync(
        Audio.RECORDING_OPTIONS_PRESET_HIGH_QUALITY
      );

    } catch (error) {
      console.log("Failed to start Recording", error);
    }
  };

  const stopRecording = async () => {
    await recording.stopAndUnloadAsync();
    const uri = recording.getURI();
    return uri;
  };

Thanks @devbalmuda! That’s right, it’s one of the limitations of an iOS simulator. See: https://docs.expo.dev/workflow/ios-simulator/#limitations

Expo team said the iOS simulator does not support the recording… so you need to test with the real phone i think. You can see the details on below link. https://docs.expo.dev/versions/v45.0.0/sdk/audio/
