Problems with HD Audio [Dell Optiplex 3070 Micro - Intel UHD 630 with Denon AVC-X4700H]

Hello guys,

i've installed the current version of libreelec and having problems with all HD audio formats. DTS Digital Master and Dolby TrueHD do not work.

In the run-up to this I have already read through a number of posts and adjusted my settings accordingly. Unfortunately the error still occurs.

About my setup:

Dell Optiplex 3070 Micro with Intel UHD 630

HDMI 2.0a extension.

Denon AVC-X4700H with 5.1 setup.

The PC is connected directly to the amplifier with a high-quality HDMI cable.

4k@60hz with HDR works very well.

Settings in Kodi:

TrueHD and DTS HD Master are enabled in Kodi. Sync playback to display is disabled.

I've tried pretty much everything and can't get any further. I would be happy if you would take a look at the log.

Many Thanks

I discovered that it works on the Optiplex with an HDMI 1.4 port. Apparently there are compatibility issues between the Denon and the Optiplex HDMI 2.0a extension.

Unfortunately, there is no bios update for this HDMI port.

Libreelec's HD audio can be passthrough, the hdmi must be origin from intel.

DELL 3070 origin HDMI is 1.4. The HDMI 2.0 is from DP.

In Libreelec 10.0.1 you can video from hdmi 2.0; audio from hdmi 1.4.

Unfortunately the Nightly can't do this.
