Hi James<br>
<br>
Thanks for the response.<br>
<br>
I installed Firefox on the 32020 build two different ways to test:<br>
<br>
1. Using 'yum install' to get it from the repo. This installs Ver 26 as per<br>
your email.<br>
2. Using the download (firefox-50.1.0.tar.bz2) from the Firefox downloads<br>
site which gives Ver 50.<br>
<br>
The behaviour of both versions with respect to the sound appears to be the<br>
same.<br>
<br>
The browsers will play an mp3 file when it is simply linked within a web<br>
site, (by default using the VLC plug-in according to the FF<br>
Preferences/Application dialogue) but will not play an mp3 file within<br>
simple HTML5 sites (eg our vt-motoli site)<br>
The Reading Eggs site works well visually (it won't work properly in<br>
Epiphany), but is absolutely silent. As far as I understand, this site is<br>
using Flash.<br>
<br>
It seems from some postings I read that FF expects to have Pulse Audio<br>
support on Linux systems (and this is not included in the XO software).<br>
So it is interesting that when you installed apulse, there is still an<br>
issue.<br>
<br>
