It's a driver feature that is enabled as default, no matter whether
you use or not :)

Does it mean that you have no headphone, or does the machine have no
headphone jack?

That's why I'm asking to test.  Usually when such a noise occurs due
to the auto-mute feature, it's because the bogus unsolicited events
are fired up too much although no jack is plugged actually.  Thus
usually the auto-mute feature itself doesn't work in such a case
(either no hardware implementation or the hardware has its own
 switching mechanism.)

Thanks.  Yes, the attachment is OK.
