Comment 5 for bug 211698

Another update:

It looks like I was wrong, regarding Epiphany and the sound with the PA backend.
In the past I had stuttering sound in Epiphany while using the PA backend.
Without being even aware of that, it disappeared thanks to a workaround suggested in some forum topic;
It might be this:

In the file ~/.pulse/daemon.conf (possibly based on /etc/pulse/daemon.conf), I've added the following lines:

default-fragments = 8
default-fragment-size-msec = 5

More lines can be added. For instance, as mentioned in the above topic (and without the fragments params):

high-priority = yes
nice-level = -11
realtime-scheduling = yes
realtime-priority = 5
resample-method = speex-float-0
