This bug is affecting the X2Go Client for Windows.
(X2Go bug 363. Our "fix" is to bundle X2Go Client win32 with the
unaffected pulseaudio win32 0.9.6 in addition to the affected
pulseaudio win32 1.1.)
It appears to only affect PulseAudio when it is running on Windows. In
X2Go terminology, the PulseAudio server runs on the X2Go Client. We
always use a "Direct Connection" as listed here with X2Go:
Anyway, I did some testing of this patch.
In summary: The patch fixes the bug when firefox + flash_plugin is
running on Ubuntu 12.04. Firefox's HTML5 audio works fine with or
without the patch on Ubuntu 12.04. However, when the apps are running
on Fedora 20, applying this patch to the win32 pulseaudio causes audio
to stop working altogether!
Note that I have not applied either this win32 patch:
nor this set of win32 patches:
I am thinking of applying both of them on the win32 client and then
retesting Fedora 20.
Note that with X2Go, the windows client is using a config file like
this (the port numbers are randomly generated):
load-module module-native-protocol-tcp port=4713
load-module module-esound-protocol-tcp port=4714
And the linux server is using a PULSE_CLIENTCONFIG file like this:
Note that we are using SSH port forwarding by default. However, when I
disabled X2Go's SSH port forwarding for pulseaudio in the past, it did
not fix this flash audio bug.
