Onkyo NR-636 Audio issue

[Gaigebacca]

Hey, nice to hear and good for you :woohoo: ...but thats really not THE solution. Anybody can upgrade HTPC gear/buy supported machine. I want it to run on my PC, which has the ability to play such sound format, and on my AVR which is also TRUE-HD x DTS-HD capable :S

That kind of came across like a jerky statement, just fyi, as I asked him to report back if he made any progress by changing out the GPU. This gives us a good insight into that it is in fact, an issue with AMD APUs and Onkyo receivers. Something in the linux driver for the AMD units is not talking with the audio over hdmi output being sent to these receivers.

The issue that I believe the poster above me is trying to make, is that with the integrated units some of us are running, we cannot switch out the GPU for a different manufacturer, so this has to be resolved on the driver level most likely.

I'm still here to help if I can. I have the AMD card sitting next to the HTPC, and will monitor this thread. Is there a particular bug tracker, here for OE or maybe over a Kodi to submit?

I can do some comparison/contrasts of debug files for the AMD v. nVIdia if needed.

I want all my OE brethren to have DTS-HD or TrueHD no matter the GPU/receivercombo! :laugh:

That would be great Thanks for your time.

Ok, I have no problems with audio.

I think this is not specific to the Onkyo reciever. I've an identical issue with DTS-HD and Dolby True HD.

I've a Yamaha RXV375 and a Gigabyte Brix A8-5545M.

Scenarios;

Video @ 60 Hz - TrueHD and DTS-HD both passthrough but with lots of skipping and stuttering.
Video @ 24 Hz - Both TrueHD and DTS-HD do not passthrough and the receiver acts as if it's receiving no sound.

I turn passthrough off on both HD types and it'll work fine at any refresh rate. Really frustrating.

Is it an issue with the AMD drivers? Is it likely to be fixed any time soon?

Same thing I have experienced, although I have not tried the 60Hz vs 24Hz for playback, but everything else, the same. Must be an issue with AMD drivers for some reason. Has someone posted this to the bug board? I am not really sure what to post or where to make sure this is widely known by the dev team.

It was @ 24Hz I originally discovered the issue. Changed to 60Hz and it seemed to be fixed (lights go on on the receiver) but it starts stuttering and dropping out (along with some painful on ear drum pops if the volume is up!).

From the googling I've done it seems to be an issue with the AMD driver or an out of date linux driver. It may be solved by updating the linux build openelec is using (or not and be a much bigger issue, I'm no dev!).

I´m on Yamaha AVR too and ION2 graphics, so it´s not AMD problem only. There are maybe just new AMD/nVidia drivers in Openelec 5+ releases. ...and we need there some older ones? Just guessing.

Found these with some quirky searches.

This does look to be a specific driver/kernel issue for AMD platforms when trying to output HD audio @ 24fps.

I submitted another post to the bug report, indicating that it is still an issue, and linked to this forum post.

I also have an Onkyo 636, but am running OE5.0 on a Cubox i4-pro and have a lot of problems aswell:
- passthrough enabled for all types: audio dropouts all of the time on all formats (so bad the indicaors on the AVR go out).
- passthrough enabled exept DTS-HD and DTS-MA: audio works like a charm but no HD formats..
- passthrough disabled: random static noise on all audio formats. reduced it a bit by disabling "sync audio to video" and "sync refresh to display"
