any idea why Linaro doesn't have any of these problems? Out-of-the-box Chromium on Linaro works perfectly and as expected.

kweb doesn't play sound either. kweb gtk3 doesn't seem to even work with javascript.
Basically the web page is php/javascript playing an mp3.
Epiphahy works, but crashes alot.
I don't understand why chromium and iceweasel won't play sound, but will through pepperflash.

I'm having sound issues in Chromium and Iceweasel. I get sound in flash, but when I try to play an mp3 in chromium there is no sound. Mp3 works in epiphany. I thought chromium was smart enough to play mp3 but I guess not? Googling led me to a chromium ffmpeg that does not exist in raspian. Any ideas?
