setMicrophoneMute(boolean) doesn't work on some devices
<p>I couldn't find any related post here (but other small posts on the internet), so here it is: </p>

<p>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.</p>

<p>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.</p>

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

<p>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.</p>

<p>Thanks</p>
