What sound backend are you using? PulseAudio?
PulseAudio yes.
Also, setting bdl_pos_adj=0 option makes any difference?
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, Catalin
