State-Changed-Why:
Patched. MFC within 3 days.
Take a look at http://people.freebsd.org/~ariff/test/eapd_inv/ , if
you want to try an experimental external amplifier switch (through
sysctl hw.snd.pcm<unit>.ac97_external_amplifier), sort of hardware
mute / unmute. You can use hint.pcm.<unit>.ac97_eapd_inv="1" to set
default inverted flags (which seems unnecessary since you can toggle
it using sysctl).
As I said, it's purely experimental.
Thanks for the patch/submission.
