Do you need to run "jackd" using "sudo" ?
This is normal when your sound card does not support hardware mixing
however both alsa-jack and alsa-pulse plugin are I/O plug
if web browser can use alsa "default" device through "alsa-pulse" plugin to
in theory the web browser can also use alsa "default" device through
"alsa-jack" plugin to jack server
assume that you don't use any OSS aplication any more
