Sometimes HDMI audio fails while fast switching between HDMI and Speaker due to codec Get Power state verb read failure.
Verb is codec driver to access codec HW. Since issue scenario involves fast switching between HDMI and speaker, there might be chance to fail read from HW and same happened in the error scenario.
Based on Display/Graphics architect suggestion, added a retry mechanism for failure on first attempt.

Does this still happen with the latest 5.3-rc kernel? The recent fix to add the write-sync for Intel platforms should already cover this kind of errors.
thanks,
