[*]# play test.wav


Input File : 'test.wav'
Sample Size : 16-bit (2 bytes)
Sample Encoding: signed (2's complement)
Channels : 2
Sample Rate : 16000




1) is it the default behavior that uuid_record record with 2 channels
2) is it reasonable that FS can record to 2 channels but cannot playback?
3) do I need to set RECORD_STEREO=false before uuid_record?




Thanks for help.
