Public bug reported:
On my Lenovo V560 notebook both on Natty and Oneiric I'm experiencing crackling
sound.
Executing this line fixes problem for me:
sudo bash -c "echo 'default-sample-rate = 48000' >> /etc/pulse/daemon.conf" &&
killall pulseaudio
So changing default sample rate from 44100 to 48000 fixes problem.
Not sure if it's entirely PA's problem or some sort of ALSA-PA misconfiguration.
