How to set the audio device mode ZegoAudioDeviceMode?

Precautions

1. On Android and iOS platforms:

   1. Call volume means enabling system 3A, Media volume means disabling system 3A.

   2. Android platform: Switching the volume mode will cause the device to restart.

      • If local audio playback is already in progress before switching, there will be a stutter during the switching process.
      • If streaming is already in progress before switching, the receiving end will also hear a stutter.

   3. iOS platform: Switching the volume mode or turning the microphone on/off will cause the device to restart.

      • If local audio playback is already in progress before switching, there will be a stutter during the switching process.
      • If streaming is already in progress before switching, the receiving end will also hear a stutter.

2. When enableHeadphoneAEC is set to false, after connecting external devices (such as headphones, external sound cards, etc.), "media volume" is always used, and the audio device mode (audio_device_mode) setting will not take effect.

3. On macOS platform: Currently the microphone is always occupied. Call volume uses system preprocessing, and non-call volume uses software 3A processing. The method to distinguish call volume on macOS platform is: first play a piece of music. If it is call volume, when starting our Demo, the music playback will be noticeably quieter; if it is media volume player, when starting our Demo, the music will not have obvious changes. For machines with Apple silicon chips, due to adaptation issues, please be sure to use General media volume mode.

4. On Windows platform: There is no distinction of audio device mode (audio_device_mode), the microphone is always occupied, and software echo cancellation is used. Windows platform has no distinction between call volume and media volume.
