I have an Intel Mac mini, with azalia audio, which has never worked.  I just
recently upgraded the kernel, still no luck.

"Never worked" means "probes fine, thinks it's doing something, but there is
never any signal output".  I did a couple of rounds of dmesg and debugging,
and never got anything conclusive.  Anyone else?  Did someone find a
workaround which I missed in the last couple of months?
