I downloaded recordPad and recorded a wav file and tried playback on asterisk got the same error as before -- WARNING [1225991360] Format.wav.c:132 check_header:unexpected header size 18--

when I recorded in gsm format on my laptop asterisk did playback well

I used sox to resample the recorded wav file on the asterisk machine into wav again and asterisk playback worked well.

The sound property of the recorded wav file is as follows

Bit Rate                128kbps
Audio sample size   16 bit
Channels               1(mono)
Audio sample rate   8 kHz
Audio Format         PCM

Is there any reason for this behaviour?
