Right. I've got one in use at home (I'll bring that, no need for network
when I'm not there), I'm not 100% sure what I did with the other. If I
find it, I'll bring it; otherwise you'll need to search for some other
solution (it's not that it's bad or anything; it's just that I once lost
the 3Com one, apparently with the recent move I now lost the other...
but I haven't looked for it very thoroughly yet))

The one at home is a 3Com 3CGSU08 (warning: evil blue LEDs), the other a
dlink thing.

That might indeed be an issue, depending on how the various applications
(the SIP client and dvsource-alsa) select their audio source. There are
two ways of selecting an ALSA audio source; by name or by number. The
latter is non-deterministic and would therefore be problematic, but the
former shouldn't be. There are several SIP clients (ekiga, for one, but
I believe that console thing that I can't remember the name of right now
can do so too) that select the audio device by name, so that side of the
equation should not be a problem; I don't know about dvsource-alsa
(never used it, tbh). Anyone?

Worst case, I suppose this should be possible to fix with a little
.asoundrc hackery, but I'd rather not go down that route if we can avoid

The volume of a pizza of thickness a and radius z can be described by
the following formula:

pi zz a
