Well, I don't mean to activate cpufreq. Rather cpufreq may be sometimes the cause of output noises.
Does the noise also on the analog loopback, e.g. CD or line-in? If yes, it's likely a problem of hardware, either the broken h/w or the bad plug/cable. Or, it's an inproper mixer configuration. To check the mixer configuration, show the contents of /etc/asound.state (it's generated via "alsactl store"), and /proc/asound/card0/codec97#0/* files.
OTOH, if this happens only on PCM, it's often an interrupt problem (typically ACPI) or the influence of cpufreq...
