Ok so I've played with suspend. OSS4 does not support suspend/resume at all. Upstream comes with two scripts "soundoff" and "soundon" which help to handle shutting down and reinitializing it.
Bad part number 1 is that those are missing from the Debian packages; good part is I've solved that by taking the scripts from the source package and adapting them to Debian, anyone interested just ask me (I'll then put them up somewhere including git repo). Bad part number 2 is that applications that like to keep the sound device open, for example ossxmix, or Qemu, have to be killed over resume cycles. No solution for this. You can't have everything and eat it too. cpufreq and battery power tests left for another time. BTW I've tested sound with ALSA on another, ~9 year old, laptop (with Cirrus Logic CS 4614/22/24/30 [CrystalClear SoundFusion Audio Accelerator] (rev 01)); on this laptop there *is* low pass filtering with ALSA, but it sounds relatively bad in another sense: the input sound is quite heavily colored; my voice sounds a bit different there, almost like from another person. When I use the sox downsampling the voice sounds natural again. So I suspect that this hardware actually *does* have an analog low-pass filter (that is changed according to the used sample frequency), but it's quality is lacking compared with what sox (or supposedly OSS4) implements in software.
