So, despite my best efforts to not have my main system update to the Creators Update (The "Defer feature updates" box is enabled), outside of my systems active hours it's installed it anyway. I could rant about that in itself all day, but perhaps for another topic.
I was wondering if anyone here since updating to it has lost the ability to use Dolby Digital and/or DTS over Optical, because mine has just stopped working despite previously working beforehand. I have my SteelSeries H Wireless headphones as the receiver, and they only support Dolby Digital. The Realtek driver on my motherboard was one that Gigabyte also licenced the Dolby Digital Live (DDL) features. Games that used 5.1 would be re-encoded to DDL on the fly and sounded great. Blu-Ray's played back in Cyberlink PowerDVD would pass-thru the pre-encoded Dolby 5.1 track.
Now however, while DDL says it is enabled in the Realtek HD Audio Manager, you only get stereo channels play back. When you open up Windows audio control panel and play a test tone, a message pops up saying "This format is not supported". When I play a Blu-ray, it's just total silence if I want to use multi-channel.
I'll take suggestions on how I get it to work again...
