I haden't noticed up to now but the headset's volume control actually
sends VolumeUp and VolumeDown events to the X server, which my window
manager acts upon for sound card #1 (headset being #2). So no need for a
separate daemon here, a simple reconfiguration of my wm will suffice.
What I'd like to understand is why these events are visible to the X
server (using xev)? My /etc/X11/xorg.conf has no particular section for
the headset.

Same here on debian.

I'd rather try to direct the volume knob events towards X and capture
them at the wm level, but they don't appear in xev. I tried making a new
section in xorg.conf with /dev/input/event2 and Driver "mouse" and the
events do appear but interfere with the pointer (no surprise there ;).
It boggles me that headset volume events appear in xev(1) and not
keyboard volume knob ones... but that is off-topic to alsa.
