Hi all, I have had the exact setup & the same problem as described above since ages. But, today I finally fixed it, well at least on my NUC.
I installed GFX driver 10.18.10.3958:
This driver is meant for the D34010WYK but it works for the N2820 as well
When checking the supported audio types I saw:
DTS Audio
Dolby Digital Plus
DTS-HD
Dolby TrueHD
Dolby Digital
I immediately checked the Netflix Metro App, and indeed, FINALLY no more stutter and working 5.1 audio.
Unfortunately XBMC Gotham 13.2 did still not work. I tried everything but no success. So...I downgraded to Frodo 12.3, and it worked instantly with the WASAPI driver... Now playing a video with DTS-HD MA audio
I am very curious if I somebody can follow the same steps and confirm that it works?
