** Description changed:
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.
