Running Windows 10Pro 64bit Fall Creator's update connected with an HDMI cable to a DENON receiver. I can't get the NUC7i5BNK to output audio at 44.1/16 using WASAPI.
Things that I already tried:
- Updating BIOS to ver 0054
- Updating HDMI Firmware to 1.72
- Updating Graphic driver to 15.60.0.4849_BN
- Install software guard extensions 1.8.106.40803
- Currently using JRiver Media Center 64bit. Updated to latest version
- Tried using TIDAL
- Tried to output sound through Windows own audio device properties (advance tab). Selected 16 bit 44100 CD quality
Basically the problem is such: The NUC7i5BNK is not outputting any sound for 2 channels audio at 44.1/16 when using WASAPI. It will output 48/16, 96/24 or even 192/24 (2 channels) but not 44.1. Strangely enough the applications do not detect any fault, even JRiver displays the audio graphs in main window top and the DSP analyzer window.
Switching the output in JRiver to direct sound will return the audio, but then I guess it's because it's being routed through the system audio mixer and probably re-sampled to another frequency.
I have no problems with multi channel PCM audio decoded by JRiver or even DD AC3 pass through. It's just 44.1/16 2 channel audio that refuse to play through HDMI.
I also tried to output the sound through an external USB DAC and it works flawlessly, so obviously it's not an application problem and is clearly restricted to the WASAPI implementation of the HDMI audio driver.
TIA
