DTS-MA and Dolby TrueHD Issue (Generic/AMD GPU)

xizor81 · November 14, 2016 at 11:38 PM

I have a problem having no audio with DTS-MA and Dolby TrueHD files with passthrough enabled on my HTPC (my GPU is a Radeon HD 6450).

I'm using LibreELEC.Generic. I tried 7.0.2 and 7.90.008 ALPHA.

All files work fine with Kodi on Windows 10 with the exact same settings.

Here's my debug log: 18:06:51 T:140525176547392 NOTICE: special://profile/ is mapped to: special://m - Pastebin.com

You'll also find attached screenshots of my Audio settings (sorry if the screenshots are in French).

This is really the only thing that's preventing me from getting rid of Windows. Thanks in advance for your help.

You know that the file you played is in Dolby Atmos?

probably your gpu can't do that under linux. as amd and linux aren't the best friends.

Thanks for the super fast reply.

Yes, I tried all formats I had. Only regular DD and DTS work using passthrough. Anything above that, dead silence.

That's what I was afraid of but I wanted to validate if I had missed anything.

Any chance of an updated driver or something in a future update?

I'm not sure if that is true or not but I'll have to look it up

AMD can do DTS-HD and TrueHD just fine, but I think atmos is TrueHD + some extra channels.
