After a brief look at the documentation it does not look like the 
OMAP4/5 HDMI module could support anything else but PCM audio. It could 
of course be that the documents I have only describe the use for PCM 
audio, but in any case it would be an uphill battle as even the 
documents I have are under NDA and I am not aware of any better 
documents about the subject.

Best regards,
Jyri
