<pre>Freshly booted machines shows:
$ cat /proc/asound/pcm
00-03: HDMI 0 : HDMI 0 : playback 1

Upload reloading i915 module (w/ drv_module_reload) I get:
$ ls -1 /proc/asound/HDMI/
codec#0
eld#0.0
eld#0.1
eld#0.2
id
pcm3p
pcm7p
pcm8p
The following remains the same:
$ cat /proc/asound/cards
0 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xf7e14000 irq 36
1 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7e10000 irq 35
$ ls -1 /proc/asound/card0/
codec#0
eld#0.0
eld#0.1
eld#0.2
id
pcm3p
pcm7p
pcm8p
pcm7p and pcm8p and their ELDs are bogus.
If I try to override the EDID, I could check EID-ELD conversion working by
looking at /proc/asound/HDMI/eld#0.0. Upon reloading it seems that
/proc/asound/HDMI/eld#0.1 gets filled with ELD information.
Just reloading snd_hda_intel doesn't trigger it.
