[android-developers] Problem with AudioRecord on Samsung Moment

We have been getting reports of audio recording not working on Samsung
Moment phones on 2.1-update1.

int bufferSize = AudioRecord.getMinBufferSize(sampleRate,
AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT);
this.audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC,
sampleRate,
AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT, bufferSize);

generates these logs:

I/AudioPolicyManager( 1889): getInput() inputSource 1, samplingRate
16000, format 1, channels 10, acoustics 0
W/AudioHardwareALSA( 1889): openInputStream : mInput already exists!!
E/AudioRecord( 2618): Could not get audio input for record source 1
E/AudioRecord-JNI( 2618): Error creating AudioRecord instance:
initialization check failed.
E/AudioRecord-Java( 2618): [ android.media.AudioRecord ] Error code
-20 when initializing native AudioRecord object.

I can't find the "mInput already exists" anywhere in the source base,
could this perhaps be an error message included by the OEM?

Thanks!
