[alsa-devel] IEC61937/SPDIF

[ajay khandelwal]

Hi All,
 I have to develop driver for SPDIF output of my board connected to HDMI.

I'm not sure for following (specially IEC61937)
1) How should driver know if it is compressed audio or plain pcm
2) Is their any plugin available for IEC61937, I could see only for IEC958
3) Who should create burst preamble, some plug in or driver.

Thanks and Regards,
Ajay
