Takashi Iwai 0ebaa24c6b ALSA: hda - Add static_hdmi_pcm option to HDMI codec parser 
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.
