> 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.
