you can tell what codec chip you have by looking at alsamixer:
Card: HDA Intel
Chip: SigmaTel STAC9271D
View: [Playback] Capture  All
grep Codec /proc/asound/card0/codec#2
Codec: SigmaTel STAC9271D

(that grep is slow because the kernel takes a long time to generate the file, probably querying hardware settings, not because it's so big that grep has to chew it for a while.)

But an older AC97 on-board codec I had (some RealTek chip I think) was also only able to use 48k and up. So I guess it's not only add-in cards that resample 44.1->48.
Hmm, ok. My old via K7 mobos with AC97 I think had 44.1 kHz capable DACs.

I wonder if dmix can resample to 96kHz/24bit? That would probably avoid any audible distortion, at the expense of a lot more CPU.
