Icecast Streaming Media Server

[JUS News]

Hello!

I have an interesting (and rather frustrating) issue relating to fallback.
We are using the following within the icecast.xml file:

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

<mount>
<mount-name>/bed.ogg</mount-name>
<hidden>0</hidden>
</mount>

<mount>
<mount-name>/news.ogg</mount-name>
<fallback-mount>/bed.ogg</fallback-mount>
<fallback-override>1</fallback-override>
<hidden>0</hidden>
</mount>

<mount>
<mount-name>/stream.ogg</mount-name>
<fallback-mount>/news.ogg</fallback-mount>
<fallback-override>1</fallback-override>
<hidden>0</hidden>
</mount>

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

Each stream plays fine in it's own right, however once "news.ogg" stops streaming, in theory this should fallback to bed.ogg.
However, using either a HTML5 audio tag (in Firefox) or JPlayer, the stream (stream.ogg) appears to stop or freeze (attempts to load indefinitely) until you refresh the page before the listener can hear bed.ogg.

This problem also occurs the other way round, during handover from bed.ogg to news.ogg.


Any ideas as to why this may be? Further info below:

icecast running on Virtual Box (Ubuntu server) within a Mac Server.
news.ogg & bed.ogg are broadcast through separate instances of Edcast with identical settings on two different standalone PC's on a different network to that of the Icecast server.


Thanks in advance!
