Yep, I can confirm this though it only happens on my netbook which has
the same soundcard your notebook does. It seems to be a resampling issue
in Pulseaudio, changing Pulseaudio's resample method from speex-float-1
to speex-float-3 cleared it up for me. I suspect it's some sort of
resampling bug in the latest Pulseaudio when resampling quality is set
too low, or a perhaps a combination of resampling and buffering.
Interestingly, I do not get this behavior on my desktop with the
integrated audio card on that machine. The card is:
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS]
AC'97 Sound Controller (rev a0)
