Will that disable gapless playback?

Sounds like faith-based mixer bypassing. :)  Any way to prevent the
volume slider from affecting the volume at all?  My ALSA silders don't
affect the volume with my USB DAC.

I recently learned that if you select ALSA or "default device" the
sound is going to hit dmix and be resampled to 16-bit/48khz.  If you
specify a hardware device like hw:0,0 then dmix is bypassed.

I've gotten rid of all that stuff.

For me there's a big difference between untouched and "as untouched as
you're going to get".  Is there no clear way to get the sound through
the system without molesting it when using rhythmbox?

I want the exact same digital information in the decoded FLAC file to
hit the DAC.  High-quality computer audio is really coming of age and
I think this type of thing will be requested more and more.

I switched from Rhythmbox to gmpc a couple weeks ago.  I do like the
server/client configuration with mpd, and it's very easy to disable
the software mixer and specify hw:0,0 right in /etc/mpd.conf.
However, Rhythmbox still has the best interface I've used.  I miss it.
