I think even higher end boards with Realtek ALC1150 chips don't come with DDL, even though the chip is more than capable of dealing with it and Realtek list it as an option for OEMs (but strangely not for end users as an upgrade). I'm in the same situation as you rxracer in that my last motherboard which was Intel branded (but far from 'high end'), came with DDL drivers but my new Z170 based board does not (even though both have SPDIF Optical outputs).
What's really required (and what would solve this issue once and for all) is if DDL equipped drivers and software were made available as an optional upgrade by either the motherboard manufacturers, Microsoft or Dolby/DTS. Motherboard manufacturers already provide hardware upgrades such as daughterboards and cables etc. available at extra cost so I can see no reason why this isn't possible. If they are worried about piracy then making the purchased drivers/software locked to a given board serial no should solve that matter. I very much doubt the cost of licencing such technology into the drivers is 'exorbitant' and irrespective of the actual cost, that doesn't let the OEMs off the hook as far as why they don't offer such drivers as an extra cost upgrade (where all stand to benefit financially and it means then end users can get what they want 'the proper way')! The current situation puts a bad name on all involved so the sooner they haggle out a deal which addresses the matter, the sooner their reputations can get back on track. Putting their heads in the sand and pretending the issue will go away, is not an option.
Agreed. The way it is now is silly. A hamstrung sound chip for the sake of greed just isn't right. As for Dolby, I can't presume to know their licensing fee, but it took nearly 4 years and all sorts of issues to have DDL on Creative's X-Fi cards. And when I looked in to getting a second hand one to get around this issue they'd put up a notice that the 'Dolby Digital Live and DTS Connect Pack' was no longer being sold as of 1st June this year. I saw it just a week or so before June, but had no card. It's still up. Guess the agreement (to add the fee in to the cost of the cards) ended. It's pathetic. I ended up finding an old C-Media card for AUD$20, paired with Daniel_K's unofficial drivers. Within days of getting it the page 37 fix worked again! (I use the unzip, replace file method described above, and by many others). Got a back up at least. Might have to use it if further builds continue to have broken DDL/DTS.
