I was going to say the same thing yesterday but my recollections on
this are so very vague I kept my mouth shut for once. ;-)

If I remember correctly Thomas removed them on purpose as the HDSP
family has so many outputs and there's no way to know what a given
user is using to get to his mains. (I use 23/24 & 25/26 as my main
outputs for instance) IIRC we had conversations about letting Alsa
control volumes but worried that maybe it would drive levels on an
output that could hurt some piece of equipment. If Alsa tried to
manage the router then it would have to recreate most everything in
hdspmixer therefore just use hdspmixer.

In the end it was Thomas that decided what to do.

In my case I use the on-board sound chip as the device that Alsa uses
by default. I take that physical output and route it back into an HDSP
input and then mix its level in hdspmixer. I only really use the HDSP
software ins and outs for Jack audio. All system audio just comes into
the HDSP, is routed and then back out to my mains.
