thanks.

this stops the panic, but my alc(4) is dead in the water after
i've set any media it seems.  aah, after setting back to
"autoselect" it does eventually regain the link (though this
takes a good 20+ seconds.)

so, this patch helps the original PR.  please commit it and i
will file a PR on the new issues :)
