what happens when you run noatun from a terminal? I don't use it so
don't know that kind of output it produces... might help.
also, try using an output intensive program like mplayer or maybe xine
from a command line and see what kind of output you get...might point
you in the right direction.
i see you are using artsd which I think is the kde sound daemon, try
killing that to get a direct alsa connection without anything else
possibly interfering...
Artsd is nothing wrong, it's just used for KDE sounds.. none of
players tried was using it. For being sure, i just killed it before
next tests.
Just tried mplayer, surprisingly it played almost normal (lag every 5
or so seconds :D), i set verbosity to 5, and got some output at moment
of lag (see below).
From this i suspect it could be some kind of buffering problem. As i
understand, it's lagging when it cant play some larger chunk, so it's
trying smaller and smaller..
Anyone have any ideas what buffer i could check/increase?
Regards,
Atis.
