[bug] Unable to switch between earpiece & speaker

[rahulraj-idt]

There is a critical issue where the audio is only coming through the speaker. Additionally, Hardware.instance.canSwitchSpeakerphone is always false, and Hardware.instance.setSpeakerphoneOn(false) has no effect on iOS.
Similarly, On Android, setting room.setAudioOutputDevice('earpiece') also has no effect.
This functionality used to work in version 2.1.3

To Reproduce
This issue is easy to reproduce by running the example app and attempting to switch to the earpiece on Android. On iOS, the button to switch to the speaker is disabled.

Expected behavior
Should be able to switch between earpiece & speaker.

Platform information
iOS - 17.6.1, Android - 13

• Flutter version:
  Flutter 3.24.3
• Plugin version:
  livekit_client: ^2.2.6

Hi @cloudwebrtc Are there any plans to fix this, as it's such a critical issue?

[cloudwebrtc]

Sorry, I just saw this, trying to fix it.

[cloudwebrtc]

@rahulraj-idt fixed it, tested and can switch the handset and speaker correctly.

@cloudwebrtc It fixes the issue on android. But this still doesn't work on iOS.

[rahulraj-idt]

@cloudwebrtc on iOS, the speaker is always on and Hardware.instance.canSwitchSpeakerphone is always false & await rtc.Helper.setSpeakerphoneOn(true/false) has no effect. Seems a bug with flutter_webrtc

[cloudwebrtc]

ah, okay, let me check it.

Hello @cloudwebrtc
I'm curious to know whether you had an opportunity to check this iOS speaker issue.

fixed #617

fixed #617

@cloudwebrtc In the fix here, you set the _preferSpeakerOutput value to true. Now, in the fix here, you changed it to false. Is there a possibility that this is an Airpods problem again? Can you test it?

[cloudwebrtc]

Yes, you are right, so I guess this is the final solution.

  void setSpeakerphoneOn(bool speakerOn) async {
    if (lkPlatformIs(PlatformType.iOS)) {
      if (!Hardware.instance.speakerOn && Hardware.instance.preferSpeakerOutput) {
        await Hardware.instance.setPreferSpeakerOutput(false);
      }
    }
    await Hardware.instance.setSpeakerphoneOn(speakerOn);
  }

Hi, your demo still has this problem on iOS.

[cloudwebrtc]
