As promised, Amazon has started rolling out a sotware update for the 2nd-gen Fire TV that fixes the missing surround sound issue in third-party apps. The new software version number is 22.214.171.124 (531006420) and has appeared on Amazon’s source code page. Reddit user charveyunm has received the update and says it restored surround sound in Netflix, HBO GO, and Kodi. Remember, the update rolls out slowly at first, so it may be a few days before your specific Fire TV receives the update. Let me know in the comments if you notice any other bug fixes or improvements once you receive this update.
10/11 3:40am Amazon is telling customers that this update fixes Dolby Digital Plus issues, and that an update for Dolby Digital will arrive on November 30th.
“By this coming Monday, October 12th, you will receive an automatic software update that enables Dolby Digital Plus for customers who have a Dolby Digital Plus system (including support for Netflix and Amazon Video). An update for older Dolby Digital systems (not Dolby Digital Plus) will be distributed on November 30th.” -Amazon
