Hi There, Is ALSA sound data always from 0 to 255 ? not having negative value if I used Signed 16 bit little endian PCM format? Previously my buffer was unsigned char, and then I changed to short int. It does not make any difference. The following is my setting, I used Signed 16 bit little endian PCM format, and application buffer is short int type, the buffer size is 2(bytes per frame, since 16 bit)* channel_num. Thanks!
