--------------------------------------------

             Summary: wav16 format read file only by 320 - half of frame
                 Key: ASTERISK-26613
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26613
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Formats/format_wav
    Affects Versions: 13.7.0, 13.4.0
         Environment: Ubuntu 14.04.5 LTS 
Linux XXX 3.13.0-92-generic #139-Ubuntu SMP Tue Jun 28 20:42:32 UTC 2016 i686 i686 i686 GNU/Linux
            Reporter: Vitaly Khalmansky


format_wav.c in function wav_read() test fs-hz in line 
bytes = (fs->hz == 16000 ? (WAV_BUF_SIZE * 2) : WAV_BUF_SIZE);

but fs->hz never set and always 0 by default

This cause read only 1/2 of frame for wav16 files.
For outgoing channels cause send only 320 bytes of data.
For incoming channels send 640  maybe smoother in effect.

For repeat problem run from CLI something like 

 channel originate SIP/200 at SIP_HOST application  Playback               7bx.ru_armin_van_buuren_feat._cindy_alma_-_beautiful_life_radio_edit.riff.le

when 
a) 7bx.ru_armin_van_buuren_feat._cindy_alma_-_beautiful_life_radio_edit.riff.le.wav16 is 16000 Hz 1channel 16 bit RIFF file

b) only slin16 codec enabled for SIP_HOST by
disallow=all
allow=slin16


I think all version of asterisk minimum since 13.4.0 affected by this bug.
