Hi Lois H. Thank you for your reply!
I followed the instructions as listed here and my results were mixed.
- I no longer have to reboot the NUC (model DC53427HYE) to get sound to come back, but I do have to right click the speaker icon in the notification area (lower right of the screen in the Desktop) and open Playback Devices. When I do that, it seems to re-scan and find my receiver (Denon AVR-789). Strangely enough, every time I do this, another instance of the Denon shows up. Since your post I have tested the issue 2 times, and I now have 3 "Denon AVR" devices listed in Playback Devices. It doesn't seem to affect playback, however, since audio works fine. If I reboot with my receiver turned on, it's detected normally and shows up in only one instance.
- A dealbreaker is that I am currently using my NUC with XBMC. The current drivers have a known graphical corruption issue as discussed here: https://communities.intel.com/thread/38686?start=0&tstart=0
- The graphical corruption issue can be resolved by installing the latest beta drivers, but that's what I was running when I had this audio device problem in the first place. It's like I have to pick my poison: graphical corruption in XBMC or having to reboot to get sound after the receiver is put into standby.
- I also see sound output, even from stereo sources like MP3 files, played out as 7.1 sound.
Thank you again for your reply. I will keep tinkering and trying different settings to see if I can get this problem fixed. Of course, a new driver release is also welcome.
