Cristian reported that these models have really bad sound above 6 dB
and proposed the original patch. I've updated the comment to reflect
this change.

This reverts commit f2624791.

Łukasz Wojniłowicz reported that the change causes both internal and
external mics not working any more.  The headphone jacking issue was
fixed by his previous patch, it's better to revert to acer-aspire-4930g
model.

CONFIG_SND_JACK needs to be selected explicitly only when INPUT=y or
INPUT_SND.  The current way, INPUT=SND_HDA_INTEL isn't strict enough.

Change the quirk for Acer Aspire 5930G from model=acer-aspire-4930g to
model=acer-aspre-6530g.  The tuba bass gets muted along with the other
built-in speakers upon headphones insertion, the internal mic works
perfectly etc.

The mute-LED isn't synchronized with the actual mute state on some
HP laptops with IDT 92HD83xxx codecs.  A similar hack using
check_power_status callback is added for this codec, too.
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The dual-headphone mode with STAC/IDT codecs is useful only for machines
that have two (or more) built-in headphones.

But, some HP laptops give multiple headphone pin configs, one for the
built-in and another for the separate (likely a docking station) one.
This results in a missing speaker volume control.

This patch adds more check for the dual-headphone mode to avoid this
problem.

We tracked down the first-0.5s-hdmi-audio-samples-lost problem to the
AC_VERB_SET_CHANNEL_STREAMID command. It is suspected that many HDMI
sinks need some time to adapt to the new state.

The workaround is to avoid changing stream id/format whenever possible.

The ALC262 has a quirk entry matching with all Sony Vaio laptops
to use model=sony-assamd as default.  But, model=auto works much better
for new models in the recent driver versions, thus it's safer to disable
that default quirk entry.

Disable beep-related codes when CONFIG_SND_HDA_INPUT_BEEP isn't set.
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The beep_mode option value was wrongly defined: it must be 0 = off and
1 = on.

Also, evaluate the beep_mode value at snd_hda_attach_beep_device()
properly so that no device is created when beep_mode=0 is given.

The beep_mode parameter for snd-hda-intel module allows to choose among
different digital beep device registation to the input layer.

0 = do not register to the input layer
1 = register to the input layer all time
2 = use "Beep Switch" control exported to user space mixer applications

Also, introduce CONFIG_SND_HDA_INPUT_BEEP_MODE for default value.

Original implementation was keeping registered input device for SND_BEEP
and SND_TONE events all time. This patch changes this behaviour:
If digital PC Beep is turned off using universal control switch,
the input device is unregistered.

Explanation: The kd_mksound() send SND_BEEP and SND_TONE only to last
registered device acceping those events. It means that the HDA Intel
audio driver blocks also the internal PC Speaker device (pcspkr.c
driver) even if the HDA Beep is muted. The user can easy disable
all beeps using 'setterm -blength 0' or 'xset b off' command.

CONFIG_SND_HDA_POWER_SAVE is independent from CONFIG_SND_HDA_HWDEP.
Thus snd_hda_hwdep_add_power_sysfs() needs the check of both kconfigs.
