>Description:
	html5 sound output in firefox with the pulseaudio default eats a lot of CPU cycles and very often results in "audiostream underrun" and stuttering of the sound on my oldish Asus P4B533 with Pentium 4 @ 2.5GHz
>How-To-Repeat:
	use firefox with pulseaudio on a html5 video on my system
>Fix:
        yes, tuning pulseaudio is an option but that will take some time.
The quick fix/workaround is to use the code that's already available within
the patches of the package by adding a couple of lines to options.mk
In my /etc/mk.conf I have:
PKG_OPTIONS.firefox=-pulseaudio oss
And after compiling the firefox package I now have a somewhat
decent sound with html5 videos. No, not perfect because
sometimes when switching videos the new video plays without
sound.
