Where do I find 'Sound Preferences'?

So I'm trying to get HDMI audio working per the wiki instructions.  Everything is fine until this part:

Code: [Select]

Then select 'HDA NVidia NVIDIA HDMI (ALSA)' as output for all items in 'Sound Prefrences' and select 'HDA NVidia (Alsa mixer)' as the mixer.

That would be in the KDE control panel. But that sounds like old instructions. These days, you run the AV wizard and select the relevant ports and be good to go.
