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
