Kernel Drivers missing to get DTS-HD and TrueHD passthrough working on Intel NUC6CAYH #876

Closed megapearl closed 5 years ago

megapearl commented 5 years ago

PMS Version: 1.16.2.1297 PMP Version: 2.37.2.994-5717f996 Platform: Embedded Intel NUC6CAYH

Steps to reproduce

  1. Install https://nightlies.plex.tv/public-test/plexmediaplayer/embedded-testing/latest-full/PlexMediaPlayer-2.37.2.994-5717f996.Generic-x86_64.img.gz on Intel NUC6CAYH Configure it to let audio all passthrough.

Current behavior

  1. No Dolby TrueHD playback and no DTS-HD playback (no audio, silence)

Expected behavior

  1. TrueHD and DTS-HD playback

I installed Windows 10 on this same NUC with PlexMediaPlayer on it, and DTS-HD and TrueHD passthrough is working as expected. Also Ubuntu Linux with PlexMediaPlayer on that same NUC is doing DTS-HD and TrueHD passthrough fine.

There are 2 firmware drivers missing to get it working on the embedded intel image:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915/bxt_guc_ver8_7.bin

and

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915/kbl_guc_ver9_14.bin

I tried to put them on the sdcard in ~/.config/firmware/i915 but they won't get loaded at boot.

What to do? How can I get the firmware loaded so TrueHD and DTS-HD passthrough are working?

Hope anyone can help me out.

Best Regards, Donald.

Are there any plans to build it with LE9? Is there anything I can do to in the meantime?

Hi @megapearl. No, no plans currently. I don't believe there is a workaround aside from the steps mentioned above.

I have plex media player running with audio passthrough and video hardware acceleration on Ubuntu Linux now.
