Public bug reported:
Binary package hint: pulseaudio
After fresh install and update of Ubuntu on my Lenovo V560 laptop i've noticed,
that sound crackles on low-to-mid frequences i think. However apptort-bug's two
sound checks seems to produce same tone, but first is played normally and
second crackles.
Switching between speakers and headphones works fine.
