[asterisk-dev] Not able to play wav files in asterisk

[shalu dhamija]

Hello all, 



I am trying to play .wav file using asterisk 1.8.7.1.  I tried playing the wav files having different properties. 

The properties of the file can be seen using 'file' command or 'ffmpeg -i <filename>' 



1.  Filname: miss_audio.wav 



[root at localhost en]# file miss_audio.wav 

miss_audio.wav: RIFF (little-endian) data, WAVE audio, ITU G.711 mu-law, mono 8000 Hz 



[root at localhost en]# ffmpeg -i miss_audio.wav 

Stream #0:0: Audio: pcm_mulaw ([7][0][0][0] / 0x0007), 8000 Hz, 1 channels, s16, 64 kb/s 



I am getting the following warning in this case. 



[Dec 24 15:08:47] WARNING[26513]: format_wav.c:92 check_header_fmt: Not a wav file 7 
[Dec 24 15:08:47] WARNING[26513]: file.c:376 fn_wrapper: Unable to open format wav 



2. Filename: msg0000.wav 



[root at localhost en]# file msg0000.wav 
msg0000.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz 



[root at localhost en]# ffmpeg -i msg0000.wav 

Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 8000 Hz, 1 channels, s16, 128 kb/s 


And in this case  asterisk is trying to play the file in slin format. 



  -- <SIP/phone1-00000000> Playing 'msg0000.slin' (language 'en') 
[Dec 24 15:14:10] WARNING[26566]: app_playback.c:475 playback_exec: ast_streamfile failed on SIP/phone1-00000000 for msg0000 
    -- Auto fallthrough, channel 'SIP/phone1-00000000' status is 'UNKNOWN' 

[Dec 24 15:14:10] DEBUG[26566]: channel.c:2679 ast_softhangup_nolock: Soft-Hanging up channel 'SIP/phone1-00000000' 

Why does asterisk start playing the file in slin format. 



I would be thankful if someone can guide me to the steps for playing the wav file in asterisk. 



Regards, 

Shalu
