There might not be a fine-grained hardware mixer available, but there's
a software one that can be enabled by configuring ALSA. I've done that
on my NanoNote because I felt all the available hardware volume levels
were rather too loud.
It shows up as a second volume control slider in the same mixer panel (I
named mine PCM because that's what programs tend to look for), and is
much more fine-grained than the master hardware one, so I just leave the
hardware slider alone and use the software slider instead.
The first version I posted here of this configuration broke recording
(and was therefore pulled back out of the default distro), but I've
since fixed that. I sent the final version to this list too, so it can
be found in the list archives, but I don't think it got picked up (yet?)
by the distro maintainers.
That configuration also allows multiple programs to play (and record)
sound at the same time, though I haven't found much use for that yet,
beyond playing a bit with feedback (arecord|aplay, then aplay again)...
If you want it, I can send you the config file so you can use it on your
NanoNote - it shouldn't care what distro it's used on.
