[Freeswitch-dev] choppy sound with .wav file played in the background

[Han Xin]

Hi Callum,

Thanks for the detailed reply first! My problem was simply solved by using another
function "switch_ivr_displace_session()" to play the indication sound file. 

Anyway it is very nice of you to provide this solution, other developers may get 
benefit from your contribution. :)

Regards,
Han
