[DragonFlyBSD - Bug #2090] snd_hda does not support headphone automute

[matt martin via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2090 has been updated by matt martin.


pciconf:

pcm0@pci0:0:27:0:	class=0x040300 card=0x831a1043 chip=0x27d88086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'N10/ICH 7 Family High Definition Audio Controller'
    class      = multimedia
    subclass   = HDA

'card' is very different here. According to man: "The third column gives the contents of the subvendorid register, introduced in revision 2.1 of the PCI standard. Note that it will be 0 for older cards.  The field consists of the card ID in the upper half and the card vendor ID in the lower half of the value."

The hda sound driver does not notice jack insert/removal events.  Even when
booted verbosely, there's no action, so attaching headphones does not mute
speaker audio.

An update to FreeBSD's sound/pci/hda expressly mentions solving this problem:
