alsasrc can record from spdif and as Bhavna wrote v4l2src will support hdmi capture.

Bhana, you will need to write a small application (using python if you want). It
will be something like:
alsasrc ! audio-encoder ! muxer name=m ! filesink v4l2src ! video-encoder ! m.

You should consider encodebin as then in becomes:
alsasrc ! encodebin name=e ! filesink v4l2src ! e.
