My speakers/headphones wont disable for hdmi

[Keithard]

I use to be able to disable my speakers/headphones so I could listen through my hdmi through my tv. Now when I go to disable speakers they won't disable and I can't play sound through my LCD tv until I can disable them.

Additionally I know my hdmi works, because when I test it it will play through the tv.
