Q: No audio thru HDMI cable post-upgrade to 10.8.5

Used App Store yesterday to update OS X, Mtn Lion to 10.8.5 on my 2012 MBP.  Since then I cannot get audio to play on my TV connected via HDMI cable thru the Thunderbolt/mini display port.  It worked fine under 10.8.4.  Have tried it on two different TVs, both relatively new w/o success.  Checked Sound panel of System Extensions, of course.  Using latest VLC update to play .mp4 and .avi files, and Firefox for USTVnow.com programming. (I live in México.) Any suggestions?

MacBook Pro, Mac OS X (10.6.8)
