Thanks for the reply. Couple more questions
1. Is kcontrol "ELD" being read directly by application or there is
ALSA library API to parse the information.
2. Also, I see you submit this patch [PATCH 3/3] ELD proc interface for
HDMI sinks in 2008. I presume it's just for information purpose. You
still expect application to query for HDMI sink capability through
"ELD" kcontrol. Am I correct?
