LibreELEC-Generic.x86_64-9.95.1.img.gz on Intel NUC and hdmi video/audio

cartman74 · March 25, 2021 at 2:57 PM

Hello !

I tried the new beta LibreELEC with Kodi 19 on a spare SSD before definitely migrating my NUC.

I managed to setup my own add-ons with python3 but i still have some audio issue with this Intel NUC Audio driver and linux kernel.

I have a Sonos Arc soundbar with TrueHD Dolby Atmos capabilities.

When i launch a sample video with 3 audio tracks, it does not work with the TrueHD sound track but it works with the Dolby Atmos track and the "simple" AC3 5.1.

If you want to try the file : sample Dolby Atmos

My logs : (i cut it)

My audio device :

Are you actually using a displayport connector or is that symptom of LSPCON? If so can you try an HDMI port?

It's the problem with Intel NUC device and the driver for Audio and Video.

I only have a HDMI port but the driver emulates a DisplayPort.

My model : NUC7i3BNH

I tried to re-apply this update under Windows and replace my SSD with the Kodi one. Something strange :

Under Kodi 19 the device was recognized like this : PVT MATRIX 8*8 on DisplayPort #0 and i lost my Dolby Atmos capabilities.

Code

Device 3
    m_deviceName      : hdmi:CARD=PCH,DEV=0
    m_displayName     : HDA Intel PCH
    m_displayNameExtra: PVT MATRIX 8*8 on DisplayPort #0
    m_deviceType      : AE_DEVTYPE_HDMI
    m_channels        : FL, FR, LFE, FC, BC, BL, BR, FLOC, FROC, BLOC, BROC, TFC, TC, TFL, TFR, UNKNOWN1
    m_sampleRates     : 32000,44100,48000
    m_dataFormats     : AE_FMT_RAW,AE_FMT_S32NE,AE_FMT_S16NE,AE_FMT_S16LE,AE_FMT_RAW
    m_streamTypes     : STREAM_TYPE_AC3,STREAM_TYPE_DTSHD,STREAM_TYPE_DTSHD_MA,STREAM_TYPE_DTSHD_CORE,STREAM_TYPE_DTS_1024,STREAM_TYPE_DTS_2048,STREAM_TYPE_DTS_512,STREAM_TYPE_EAC3,STREAM_TYPE_TRUEH

Then i reboot one more time and my device was GSM LG TV on DisplayPort #0 like before my upgrade.

Very strange.

But i still have my Dolby Atmos problem under Kodi 19 ( and 18 too ...)
