[Intel-gfx] [Alsa-user] intel-hda: sound via HDMI only when using interlaced modes

[Jasper Smet]

I managed do this quickly before i got off to work:

Dmesg output with directly connected to the tv: http://sprunge.us/EhJD

Neither the VSX-928 nor the TV (passtrough) pick up sound when
connected to the AV receiver.

I noticed that when i set the resolution to 1080i at 30 sound works on
the receiver but not on the TV, everything lower works fine in both
passtrough and with the receiver powered on.

Only when using 1080p24 or lower everything then works fine on both devices..

Hope this helps.
