I copied the Implementation of your microphone button and added a few debug logs and got this

flutter: Local participant change microfone with success
flutter: Local participant change microfone - enabled: true
flutter: Local participant change microfone - enabled: false
flutter: Local participant change microfone - enabled: true
flutter: Local participant change microfone - enabled: false

using this prints:

import 'package:alto_flutter/features/meeting/presentation/videoCall/widgets/call_controls/call_control_option.dart';
import 'package:flutter/material.dart';
import 'package:stream_video_flutter/stream_video_flutter.dart'
    hide CallControlOption;

/// A widget that represents a call control option to toggle if the microphone
/// is on or off.
class ToggleMicrophoneOption extends StatelessWidget {
  /// Creates a new instance of [ToggleMicrophoneOption].
  const ToggleMicrophoneOption({
    super.key,
    required this.call,
    this.enabledMicrophoneIcon = Icons.mic_rounded,
    this.disabledMicrophoneIcon = Icons.mic_off_rounded,
    this.enabledMicrophoneIconColor,
    this.disabledMicrophoneIconColor,
    this.enabledMicrophoneBackgroundColor,
    this.disabledMicrophoneBackgroundColor,
  });

  /// Represents a call.
  final Call call;

  /// Color of the icon when microphone is disabled

  @override

    Widget buildContent(bool enabled) {
      return CallControlOption(
        icon: enabled
            ? Icon(enabledMicrophoneIcon)
            : Icon(disabledMicrophoneIcon),
        iconColor: enabled
            ? enabledMicrophoneIconColor
            : disabledMicrophoneIconColor,
        backgroundColor: enabled
            ? enabledMicrophoneBackgroundColor
            : disabledMicrophoneBackgroundColor,
        onPressed: () async {
          final response = await call.setMicrophoneEnabled(enabled: !enabled);
          response.fold(
            success: (success) {
              print('Local participant change microfone with success');
            },
            failure: (failure) {
              print('Local participant microfone error: ${failure.error}');
            },
          );
        },
      );
    }

    return PartialCallStateBuilder(
      call: call,
      selector: (state) => state.localParticipant?.isAudioEnabled ?? false,
      builder: (_, enabled) {
        print('Local participant change microfone - enabled: $enabled');
        return buildContent(enabled);
      },
    );
  }
}

@RazvanTamazlicariu, is it correct that when it goes to microfone - enabled: true that's because you press the button and it goes automatically back to microfone - enabled: false?

Can you set the log levels in the StreamVideo options to verbose? https://github.com/GetStream/stream-video-flutter/blob/main/packages/stream_video/lib/src/stream_video.dart#L1403

Maybe something is wrong with the permissions.

@renefloor yes, thats correct. microphone is on, I press on it to mutes it, and then it begins to toggle between states
