My application uses AudioRecord to record streaming voice. On ANY OTHER Android device it initializes properly and works great, excluding Motorola Milestone, which force closes and the log shows:
01-17 14:08:41.124: DEBUG/AudioHardwareMot(1059): AudioMgr:AudioHardwareMot:penInputStream enter
01-17 14:08:41.124: DEBUG/AudioHardwareMot(1059): AudioMgr:AudioStreamInMot::set(0xaf00, 40000, 1, 10, 8000)

01-17 14:08:41.124: ERROR/AudioRecord-Java(2190): [ android.media.AudioRecord ] Error code -20 when initializing native AudioRecord object.
Sometimes it happens, sometimes it doesn't, and looking into the platform source code doesn't clarify it. It returns with BAD_VALUE error code. The code in AudioFlinger.cpp that does that:
The code that initializes AudioRecord:
Again, it works fine on any other device, including Droid.
Thanks for any help!

2931 recordTrack = new RecordThread::RecordTrack(thread, client, sampleRate,

2933 }
2934 if (recordTrack->getCblk() == NULL) {
2935 // remove local strong reference to Client before deleting the RecordTrack so that the Client
2936 // destructor is called by the TrackBase destructor with mLock held
2937 client.clear();
2938 recordTrack.clear();
2939 lStatus = NO_MEMORY;
2940 goto Exit;
2941 }
2942
2943 // return to handle to client
2944 recordHandle = new RecordHandle(recordTrack);

2947 Exit:
2948 if (status) {

The code that initializes AudioRecord:
Code:
record = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, AudioRecord.getMinBufferSize(8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT) * 4);
Again, it works fine on any other device, including Droid.
