No, the artifacts are still present.

The artifacts appear only with some applications, for example VLC and
Skype have them but KDE's startup sound and music played in Amarok
don't. The artifacts also go away after around 10 - 30 seconds of
playback and happen again for some tens of seconds after restarting
the application.

The alsa-info output is available at [1] for the working case and [2]
for the broken case.

Does this help? Thanks,
