@ -153,6 +153,16 @@ card*/codec#*
Shows the general codec information and the attribute of each
widget node.
card*/eld#*
Available for HDMI or DisplayPort interfaces.
Shows ELD(EDID Like Data) info retrieved from the attached HDMI sink,
and describes its audio capabilities and configurations.
Some ELD fields may be modified by doing `echo name hex_value > eld#*`.
Only do this if you are sure the HDMI sink provided value is wrong.
And if that makes your HDMI audio work, please report to us so that we
can fix it in future kernel releases.
