channels 4/6 which are not supported by some older
NVIDIA GPUs.

The dynamic PCM restriction based on ELD information may lead to the
problem in some cases, e.g. when the receiver is turned off.  Then it
may send a TV HDMI default such as channels = 2.  Since it's still
plugged, the driver doesn't know whether it's the right configuration
for future use.  Now, when an app opens the device at this moment,
then turn on the receiver, the app still sends channels=2.

The right solution is to implement some kind of notification and
automatic re-open mechanism.  But, this is a goal far ahead.

This patch provides a workaround for such a case by providing a new
module option static_hdmi_pcm for snd-hda-codec-hdmi module.  When
this is set to true, the driver doesn't change PCM parameters per
ELD information.  For users who need the static configuration like
the scenario above, set this to true.

The parameter can be changed dynamically via sysfs, too.

So far, Realtek auto-parser assumed that the multiple pins are only for
line-outs, and assigned the channel names like Front, Surround, etc for
the multiple outputs.  But, there are devices that have multiple
headphones, and these can be better controlled with the corresponding
control-name like "Headphone" with indicies.

When multiple headphone pins are defined without line-out pins, the
driver takes them as primary outputs.  But it forgot to set line_out_type
to HP by assuming there is some rest of HP pins.  This results in some
mis-handling of these pins for Realtek codec parser.  It takes as if
these are pure line-out jacks.

If the "Volume" suffix is not given, alsa-lib gets confused and
loses the dB information at the simple element level.

Boosts generally affects both playback and capture, as they are
applied early in the chain. Hence no "Playback" or "Capture" in

The load_mixer_volumes() function, which can be triggered by
unprivileged users via the SOUND_MIXER_SETLEVELS ioctl, is vulnerable to
a buffer overflow.  Because the provided "name" argument isn't
guaranteed to be NULL terminated at the expected 32 bytes, it's possible
to overflow past the end of the last element in the mixer_vols array.
Further exploitation can result in an arbitrary kernel write (via
subsequent calls to load_mixer_volumes()) leading to privilege
escalation, or arbitrary kernel reads via get_mixer_levels().  In
addition, the strcmp() may leak bytes beyond the mixer_vols array.

the bias is put down immediately after stopping the first stream.
