Firefox on XO

T Gillett
Hi James

Thanks for the response.

I installed Firefox on the 32020 build two different ways to test:

1. Using 'yum install' to get it from the repo. This installs Ver 26 as per your email.
2. Using the download (firefox-50.1.0.tar.bz2) from the Firefox downloads site which gives Ver 50.

The behaviour of both versions with respect to the sound appears to be the same.

The browsers will play an mp3 file when it is simply linked within a web site, (by default using the VLC plug-in according to the FF Preferences/Application dialogue) but will not play an mp3 file within simple HTML5 sites (eg our vt-motoli site)
The Reading Eggs site works well visually (it won't work properly in Epiphany), but is absolutely silent. As far as I understand, this site is using Flash.

It seems from some postings I read that FF expects to have Pulse Audio support on Linux systems (and this is not included in the XO software).
So it is interesting that when you installed apulse, there is still an issue.

G'day Terry,

You didn't mention which version of Firefox.

With firefox-26.0-2 from the Fedora 18 repository your no-sound issue
with those sites reproduces.

Then I installed apulse, a PulseAudio emulation for ALSA, but the
problem persisted.  Looking at /proc/$(pidof firefox)/smaps the
libpulse libraries are not mapped.

Which Firefox are you trying, and how are you trying it?
