I've setup a conference bridge that has perpetual-sound set to a icecast stream.  When the first person connects, there is an ~7s delay before any audio is heard.  This is similar to a problem reported by Dan here and concluded with Tony adding the channel var "enable_file_write_buffering".  The list discussion ended here: http://lists.freeswitch.org/pipermail/freeswitch-users/2009-February/011104.html


I set this var in my dialplan:
        <action application="set" "enable_file_write_buffering=false"/>

prior to joining the conference.

The first person in still sees a 7s delay on audio the first time in.

Like dan, I have icecast setup with
burst_on_connect set to 1
but my burst_size is the default 64k so quite a bit of data.

Has anyone been able to get an on-demand shoutcast stream from an icecast server to start immediately (or at least within a second)?

Thanks.
