--- Comment #22 from Mika Kahola <mika.kahola at intel.com> ---
The tests tries to check if we have valid eld in sound systems
/proc/asound/HDMI. Some monitors doesn't support audio so the test first reads
EDID from the monitors and then forces audio support on that EDID and computes
a new checksum. Finally, this EDID is forced to use. 

The display connector is forced on and the test checks afterwards if we have
valid eld on /proc/asound/HDMI/eld#0.0.

This test seems to fail because we are not able to register pins such as

snd_hda_codec_hdmi hdaudioC0D2: HDMI: pin nid 5 not registered
