Title:
Crackling Sound on PCI card
Status in The Linux Kernel:
Fix Released
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
On my CyberpowerPC Gamer Xtreme 1030 desktop running up-to-date Natty
Narwhal 64bit on fresh install, there is a variable crackling
overlaying the sound on my card when any sound is playing. It is
invariable to the output, as looping the same clip does not cause
crackling to loop. The output of sudo aplay -l is:
card 0: M1010LT [M Audio Delta 1010LT], device 0: ICE1712 multi [ICE1712 multi]
Subdevices: 1/1
Subdevice #0: subdevice #0
Any idea's on what this is? Occurs with pulseaudio on or off (even
with speaker-test), and only on my Delta 1010LT sound card. Jaunty
livecd plays audio without crackles, while Natty livecd produces
crackles.
WORKAROUND: nohz=off
