[alsa-devel] [PATCH 2/2] ALSA: hda - detect jacks on VT1708 even when no streams are active

[David Henningsson]

These days, GUIs such as Gnome sound settings want to be able to
show the correct jack status even when no streams are currently
running. I doubt this gives any measurable difference in power,
but if it does, the "Jack Detect" control can still be used to
turn polling off.
