Hi Thomas,
Sorry to dig up this oldish discussion and if I missed some of the
ideas.. but it's actually quite interesting.

The whole setup will be mounted at a remote location inside a larger
machinery for audio surveillance of said machinery (fault detection
etc.). The larger machinery of course may not be running while opened to
install our setup, thus setting the gain has to be done remotely.
The PC in this setup has an x86_64 CPU running Ubuntu 12.04 LTS, but the
case is too small for PCI(e) solutions, doesn't have firewire, so the
only option is USB.
Does the audio interface *have* to be inside the machine as well? What I
mean is Couldn't you just have the mics in the machine and the audio
interface outside (and accessible) so as to possible set the gain, fine
tune, turn on/off etc.?
Maybe I totally misunderstood the set-up but if what I wrote above were
somewhat feasible you might drop altogether the software-controlled gain
requirement?
Lorenzo.
