Help with OSS4 and HDMI sound with AMD/ATI 4850 card, is possible?

Hello, I have a TV connected through a dvi-to-hdmi cable. With alsa or alsa + pulseaudio the image and sound works but with I prefer OSS because is easier to configure and the sound quality is better among other things, the only problem is it does not recognize the hdmi sound output.

I followed the wiki to install OSS.

MODULES=(!soundcore ...

I want to know if is only possible with alsa/pulseaudio or if there is a way with OSS.
Help appreciated.
