OK, your device seems to work if there is a switch of infoframe,
ie. coupled with the "HDMI: updating infoframe" message.

Note that the message only happens if the audio infoframe don't match
up with previous one, _or_ the previous one has been wiped out by some
reset operation:

        Data Island Packet Data
        -----------------------
        The contents of this buffer are cleared during function reset
        or HD audio link reset.

Could you try dumping the audio infoframe data at the beginning of
hdmi_switch_infoframe() or hdmi_stop_infoframe_trans(), to check if
the previous content have been reset to 0?

Thanks,
Fengguang
