音频管理器蓝牙在SamsungS9，Note8上无法正常工作

这是我必须处理音频的代码：

fun setSpeakerValue(value: SIPManager.AUDIO) {
speaker = value
when (value) {
SIPManager.AUDIO.EAR_PIECE -> {
binding.callItemIconSpeaker.setImageResource(R.drawable.speaker_off)
if (Build.BRAND.toLowerCase(Locale.ROOT).contains("oneplus")) {
audioManager?.mode = AudioManager.MODE_IN_COMMUNICATION
} else audioManager?.mode = AudioManager.MODE_IN_CALL
audioManager?.stopBluetoothSco()
audioManager?.isBluetoothScoOn = false
audioManager?.isspeakerphOneon= false
speaker = SIPManager.AUDIO.EAR_PIECE
}
SIPManager.AUDIO.SPEAKER -> {
binding.callItemIconSpeaker.setImageResource(R.drawable.speaker_on)
audioManager?.mode = AudioManager.MODE_NORMAL
audioManager?.stopBluetoothSco()
audioManager?.isBluetoothScoOn = false
audioManager?.isspeakerphOneon= true
speaker = SIPManager.AUDIO.SPEAKER
}
SIPManager.AUDIO.BLUETOOTH -> {
binding.callItemIconSpeaker.setImageResource(android.R.drawable.stat_sys_data_bluetooth)
if (Build.BRAND.toLowerCase(Locale.ROOT).contains("huawei")) {
audioManager?.mode = AudioManager.MODE_IN_COMMUNICATION
} else audioManager?.mode = AudioManager.MODE_IN_CALL
audioManager?.startBluetoothSco()
audioManager?.isBluetoothScoOn = true
speaker = SIPManager.AUDIO.BLUETOOTH
}
}
}


现在，这对于我尝试过的所有手机都可以正常使用。但是对于Samsung S9和Note8，当我的SIP通话已连接时，它将首次选择蓝牙。

在那之后，更改为EAR_PIECE并没有任何作用，然后更改为Speaker，将其设置为扬声器，仅此而已。

无论我叫什么，它都会在Speaker上保持阻塞状态。

请帮助，其他人有这个问题吗？
