Hi, all
I'm an Nvidia engineer, I maintain the nvidia linux hdmi audio driver.

An end-user report a problem with his TV attached to an MCP89.
ALSA won't send audio to it, because
HDMI hot plug event: Pin=5 Presence_Detect=1 ELD_Valid=0
HDMI hot plug event: Pin=5 Presence_Detect=0 ELD_Valid=1

As you know, in linux driver patch_hdmi.c, it use (pind && eldv)
in unsolicited events. So the driver can't detect the monitor.
