The libsamplerate resampling method is pretty CPU intensive, check http://blog.ivitera.com/pavel/linux-audio/...ing-libsoxr-lsr (http://blog.ivitera.com/pavel/linux-audio/pulseaudio-with-ld_preloading-libsoxr-lsr)
Alsa - if your apps use PA exclusively, no need to change anything there. In PA-enabled distributions the default alsa device is configured to be just a bridge to PA.

I know. I've edited my pulseaudio config file to refect that, but it still downsamples

So I really can't figure it out. Banshee/Audacious is outputting bit-perfect to pulse, which should be sampling the material at 24/96, which ALSA should accept at the native resolution. But something is broken in that chain.
If the listing is your current setup, I see the corresponding options commented out, i.e. inactive.
Wow. I can't believe I missed that.
Sorry, that fixed the problem.
