Dolby Digital HDMI Pass Through

Unread postby virusalert » Thu Jan 02, 2014 4:58 pm

Hi, I have an Odroid-U2 with Android Pocket Rocket and the only issue is it can't decode the dolby signal. I tried to use also Ubuntu and all other linux versions, but XBMC can't play correctly 1080p files.
If I'll buy a Odroid-U3 it can decode correctly Dolby signal, using Android or Linux?

We don't have any firm schedule to implement the pass-through feature.
Sorry!

When playing dts-audio files, xbmc switches automaticly to audio passthrough. So I guess it's not the hardware? When playing an mkv with dts audio, it doesn't work.

Hi,
Just bought U3 to run XBMC connected via HDMI with my av-receiver 1080p movies works perfectly on android XBMC (Gotham stable android arm release) but without passthrough i cannot use it for replacing my Raspberry Pi as an HTPC. I'm quite disappointed as i spend so much money (shippment plus customs to Germany). A lot of friends are awaiting my comments/ experience with U3. They have as well Raspberry as MediaCenter and want to replace this slow machine. Are there any plans to get passthrough running? Is this a problem because of hardware limitations?

Hopefully I get a positive answer and I can replace the RPi soon. -.-

thanks RapidSummer

+1 (Same request here - I hope this will be resolved soon, I don't see any point of having XBMC box capable of stereo playback in HDMI age :( )

Just to clarify...I'm also interested in being able to play back videos with DTS sound. What does this mean exactly? I won't get any sound - or I will get sound but only a plain stereo signal through HDMI? I assume "passthrough" means sending the unaltered DTS signal over HDMI to the TV (or receiver) to be decoded externally. Correct?

DTS is decoded on ODROID and down-mixed to stereo.

Unfortunately, there is no plan to support the pass-through because we have limited knowledge on that.

And this is the same for all of the "HD" sounds? I mean AC3 or True HD or so, what XBMC supports? I've tried yesterday the sound playback on my Philips HTL9100 soundbar, but in XBMC in "Passthrough output device" field, there was some error/failed text only. This means, the XU does not support any passthrough options? Really disappointed :cry:

You might have success with some external sound card (USB) -- if they are supported in Linux (have drivers that support passthrough).

Hi,

I could manage an external sound card (Xonar U7), and it seems to be working. When I'm turning the volume knob on xonar, Android feedback to the screen the actual level of volume. However, all of the sound I can hear on the TV's speakers (I assume, due to the HDMI connection between the XU and the TV). I've installed the USBaudioTester app, and it shows, there are a lot of sound device, and one of the is the Xonar. How can I setup the Xonar as the default/primary sound device?

With XBMC 13 for android and hdmi pass through, odroid would be the ultimate HTPC.
You guys should serious think about supporting It. Maybe some crowdfunding to make It available.

Maybe Odroid dev should ask for help to openelec developpers,
with the specs of a odroid u-3 there really is not reason not to be able to support 1080p and audio and everything

In my opinion it would be a wise business move to get those things working perfectly. Like many people i bought a u3 hoping to replace the slower but better media player (rpi) and waiting to buy 7-8 more for family and friends but that will not happen in the current situation.

These are developer boards; so there is a bit of assumption the buyer knows what they're getting into before hitting the checkout button. If HK's market was entertainment, diddling with 1080p 50/60 Hz (or whatever else they use in the rest of non-civil, non-NTSC world) wouldn't even even an issue I'm sure.

That said, I haven't seen really any ARM SoC truly suitable for a HTPC. Yeah, the Raspi gets there with video, but blech, you can't do anything else with it.

You can't ask a $59 board to do what your $2k desktop/laptop does.
Sadly what people don't even know is that 99% of their desktops doesn't have hardware acceleration for video decode.
Its just a .. fuck.. do it on CPU.

My i7 Desktop with nVidia gpu using the closed drivers does software decoding of all videos. including youtube and all the crap.

In theory ARM hardware can do almost the same but requires you to fully customize all the userland drivers.

For example take the huge effort Google had to make in order to get Flash working on the ARM Chromebook. All their work is even closed.

ARM has showed a design for a standard video decoder block, if manufacturer's adopt that block instead of this current custom madness everyone will benefit for that.

That odroid is a developer platform and costs only $59, everybody knows that. But what supports hardkernel, isn't odroid sales ?
The HTPC community would be thrilled with the possibility. Myself would buy one unit for each TV the I own.

Putting 2 and 2 together (Developer Board + Media Center), this is a great opportunity for you to learn how HDMI passthrough works, and delve into what modifications might be needed to do so. All kernel code is Open Source: https://github.com/hardkernel

Its unrelated to the topic of course..
But a new Ubuntu image, due for this week will have XBMC working 1080p videos just fine.
The major issue is now fixed and there's only a single issue to be fixed now on hardware decoding that affect only a very small portion of videos on the webs.

Again, its a dev board that is capable of far more than just crunching videos. To dismiss the entire platform because of HDMI passthrough means that youre better off with an out-of-the-box solution.

Hi,

I understand a good audio and video performance/capability are important for many people. Me too. My goal on mid term to use my XU as a full featured desktop PC replacement and media player. Currently a good news, that I could get audio passthrough from my XU via my USB attached Xonar U7 sound card. I'm using that xbmc image http://forum.odroid.com/viewtopic.php?f=61&t=2589, any in XBMC I can see the Xonar as USB SPDIF device, and can passtrough DTS/Dolby sounds. It works well!
I will post a note with detailed setup in the above mentioned thread.

Philips Fidelio HTL9100/12.

XU connects via HDMI to my Samsung TV, and via the USB Xonar U7 to Philips Fidelio. Between the Philips and Xonar U7 I have optical SPDIF cable. XBMX running on XU recognizes my sound card as SPDIF capable audio passtrough device.

Just an offtopic question: how can I create screenshots from my xbmc running on XU? I would like to attach them into the post.

Thank you for the answer. I'm heavily considering to buy a audio receiver. ;)

There should be a screenshot application which has the adjustable timer even I didn't try.
Set the timer to 10 or 20 seconds and run the XBMC.

Hi,
I could not manage to get installed any screenshot apps, so I taken a photo of my screen :-)
Unfortunately the settings seems to be correct, but I could not hear anything from my soundbar. These are the settings in xbmc audio panel:
CAM00067.jpg


So it seems, everything are correct, the XU can recognize my Xonar correctly, but still, there are no output from the soundbar. How can I check, whether the output is redirected well to the spdif output? I've checked the Xonar, the SPDIF cable on another PC, and it works well. When plug the soundbar via the 3,5mm jack connector to the xonar, I can hear the sound (choosing the analogue output). The strange thing is that on Monday I could manage to get the sound out via spdif of xonar, but I can not recall the exact settings.

Any idea how can I monitor whether the sound goes well to spdif or not? I assume something is wrong with the default sound output or so...

I'm trying the passthrough feature with Creative USB sound card which has the optical SPDIF output on mdrjr's latest XBMC/Lubunut image on my U3.
But I have the same issue with you.

It seems to be related to the hard-coded configuration in Pulseaudio.
But I have very limited knowledge on this new area and even I have no AC3/DTS receiver yet. :oops:

s_20140409_170933.jpg


Can you hear any sound from analog output of USB sound card?
I can't even I adjust several options :cry:

I will try alsamixer later.

Hi.

I'll double check today evening the exact settings, but when I've connect the soundbar with RCA cable to Xonar (from yonar's headphone jack output via jack/rca cable), I can hear the sound from my soundbar. As I recall, in audio output device, there was several option: Xonar SPDIF, Xonar Analogue, Odroid's MAX0xxxx chip, and maybe some other.

I think somewhere in the background should have the same configuration items. I mean, in CLI using ssh, I can see somehow the Xonar itself (ie. cat /proc/dev/) and mabe it is mandatory to change the default sound card/interface in the system. It is a good sign, that XBMC already recognizes well the Xonar, but somehow the output is going to a wrong direction :-)

For passthrough, I think it's better trying with ALSA directly and uninstall pulseaudio.

try running:

For instance the Freescale's i.MX6 SOCs have working HDMI pass through in Linux (also under xbmc). so if anyone is up to the challenge it could be worth looking into how it's implemented there.
