[Intel-gfx] Intel Sandy Bridge HDMI audio modes auto detection fails

Maybe i am at a wrong place with this. but could you please help where i
should turn to with this problem.

I already reported this bug at Alsa, but no reaction from them at all.

The main problem is that /proc/asound/card*/eld#* file gets wrongly filled
with autodetected available HDMI audio modes.

As i understand, alsa is just using this file, but the modes listed here,
should be detected by the gfx driver. Manually triggering the settings make
the unavailable sound modes work.

Everything is described in the alsa bug report, with tons of info.

Thanks for your help,

Alan
