hi, have you a asound.conf? if you have not, please try it.
and your problem seems opposite to me :( i can't get the audio recorder work for such a long time. would you like to share you solution with me? question-1: when recording, what is the number of channelCount, 1 maybe an invalid argument, right? question-2: from the log, your capture bufferSize is 3072, how did you decide it properly? question-3: my problem is that in AudioFlinger.cpp record::threadLoop() because of the 'buffer.frameCount != inFrameCount', it is always being the overflow situation, someone suggested commending that sentense, but after that, the recorder is still without any voice. would you like to tell me something about it? Thanks a lot.
