>Description:

        I can't coax my MacBook into producing audio output --
        `audioplay -d /dev/audio foo' produces output neither in the
        internal speakers nor through the headphone jack.  I have also
        tried a NetBSD 5.1 kernel with azalia(4), to no avail.  (I may
        have needed to wire up mixerctl in some hairy way to make it
        work with azalia(4), and I didn't try very hard to do that.)

        Here's some relevant information from the -current kernel.  Let
        me know if you want more -- e.g., any kind of debugging output
        from the hdaudio(4) driver.

>How-To-Repeat:

        Install NetBSD on a MacBook1,1.  Attempt to make audio output.
        Watch the little red light in the headphone jack with chagrin.

>Fix:

        Yes, please!  Unfortunately, the solution to PR kern/44484
        doesn't solve my problem.
