The problem is now resolved, I had make several mistakes: I had forgot to release the recorded sound. (record.release();) I hadn't put the complete path for the sdcard which in fact prevented the emulator from loading one. audio-in is useless with windows, plug and play does the job. I didn't play the sound from the path I had recorded it in. The sdcard must be a *.img file and not a *.iso (*.iso doesn't work for me)
