As no one else is using it maybe Fons can convince his boss to donate it
to a worthy student recipient attending the LAC.

That person might not have much money but they might have the time to
figure out where the buzz comes from and do something productive. Who
knows they might even be able to provide useful feedback to Behringer that
improves their Linux solutions.

Sounds like everything else on the board was working ok so a little bit of
hum should be relatively easy to solve. Maybe it just needs some contact
spray.
