void
AudioManager::HandleAudioChannelProcessChanged()
{
  // Note: If the user answers a VoIP call (e.g. WebRTC calls) during the
  // telephony call (GSM/CDMA calls) the audio manager won't set the
  // PHONE_STATE_IN_COMMUNICATION audio state. Once the telephony call finishes
  // the RIL plumbing sets the PHONE_STATE_NORMAL audio state. This seems to be
  // an issue for the VoIP call but it is not. Once the RIL plumbing sets the
  // the PHONE_STATE_NORMAL audio state the AudioManager::mPhoneAudioAgent
  // member will call the StopPlaying() method causing that this function will
  // be called again and therefore the audio manager sets the
  // PHONE_STATE_IN_COMMUNICATION audio state.

  if ((mPhoneState == PHONE_STATE_IN_CALL) ||
      (mPhoneState == PHONE_STATE_RINGTONE)) {
    return;
