Brilliant! ... but when I tried connecting a pair of dumb little
speakers (no keys; no mic), I still hear static, even after:
g1-254(10.1-S)[18] foreach n (`jot 4 0`)
foreach? echo " mixer ${n}:"
foreach? mixer -f /dev/mixer$n
foreach? echo ""
foreach? end

I appreciate the rather clever insight, though! :-}
