setMicrophoneMute（布尔）不会在某些设备上工作 [英] setMicrophoneMute(boolean) doesn't work on some devices

问题描述

我找不到任何这里有关的职位（但在互联网上的其他小职位），所以这里是：

I couldn't find any related post here (but other small posts on the internet), so here it is:

AudioManager.setMicrophoneMute（布尔）不会做，我用测试了一些特殊的设备什么：谷歌Nexus S，三星Galaxy S和摩托罗拉里程碑。 在任何其他设备效果很好。

AudioManager.setMicrophoneMute(boolean) doesn't do anything on some particular devices that I tested with: Google Nexus S, Samsung Galaxy S and Motorola Milestone. On any other device it works well.

它甚至保持其状态，并返回一个布尔值，如果它得到了静音\静音，但它没有静音 - 麦克风继续记录 - 无论是在GSM通话和AudioRecord计划录制。 没有指示日志消息。

It even maintains its "state" and returns a boolean as if it got muted\unmuted, but it doesn't mute - microphone continues to record - both in GSM call and in AudioRecord programmatic recording. There is no indicative log message.

我也搞砸权限（android.permission.MODIFY_AUDIO_SETTINGS，android.permission.RECORD_AUDIO），没有什么新意。

I also messed with permissions (android.permission.MODIFY_AUDIO_SETTINGS, android.permission.RECORD_AUDIO), nothing new here.

有没有其他人遇到？有没有人有一种变通方法或神奇的解决方案？ 如果我使用AudioRecord我只是实现自己的静音这些设备 - 我不会把所记录的缓冲区。但它不能帮我带静音麦克风在GSM通话，这是我所需要的。

Did anyone else encounter that? Does anyone have a workaround or a magic solution? If I use AudioRecord I just implement my own "mute" for these devices - I don't pass on the recorded buffers. But it can't help me with muting the mic in a GSM call, which I need.

感谢
