Kodi 17.1 audio passthrough issue

Hi Justin:

If it helps, here's a bit more info. BTW, I'm using a 495Pro (Build MyGicaS905V1.30), Kodi 17.3 and an Onkyo Receiver.

When the 495Pro has a fresh restart, my Onkyo's front display shows "PL II Movie" (Pro Logic II) and I can hear system sounds as I navigate around the main MyGica menu.

When I start Kodi for the first time, the Onkyo switches to "All Ch St" (All Channel Stereo). I can hear the Kodi menu sounds and the MyGica system sounds continue working as well. At this point, I can successfully play (and hear) any 2.0 or 5.1 video. As long as I stick to 2.0 videos, the Onkyo keeps showing "All Ch St" and all menu/system sounds keep working. As soon as I play a 5.1 video, the Onkyo switches to "Dolby D". The 5.1 movie sounds great but all menu/system sounds stop working. I can continue playing 5.1 videos perfectly but 2.0 videos are now silent and the Onkyo remains at "Dolby D".

Like Bucks_Fizz mentions, the only way to play a 2.0 video (with sound) after playing a 5.1 video requires the 495Pro to be restarted.

Thanks for the explanation

We were able to reproduce this all here

So now trying to fix this issue.

Hi all,

I am having the same issue. When watching a video with 2 channel audio, all is fine. Thereafter i select a movie with DTS sound. It plays fine, but when i go back to the 2 channel audio file, there is no audio. Have to reboot the box.

Passthrough is allowed, AC3 is on, connecting to Yamaha Receiver via HDMI.

Further "googling" found:

Android Firmware that meets the IEC61937 Audio standard used in SPMC 16.6.0 / Kodi Krypton v17 currently includes the Xiaomi Mi Box, MINIX U9-H, nVIDIA Shield, WeTek Hub and the soon to be released WeTek Play2 MM Firmware update.

Any other Android Kodi boxes not implementing the IEC standard in Firmware will have DTS, DTS-HD and TrueHD Audio Passthrough issues with Kodi Krypton. These devices must use Kodi Jarvis for DTS & HD Audio passthrough (usually only AML S905 MINIX and WeTek) - OR Transcode the Audio to AC3, using the following Kodi Audio settings:

NOTE: In Kodi Settings > Player > Video > Sync playback to Display ...must be disabled to get any working Passthrough Audio

Number of Channels: 2.0
Passthrough: On
AC3: Yes
AC3 Transcoding: Yes
DTS: No

Basically my question is: Does the 495 Pro meet the above requirements (IEC standard) - or is a rolback to Kodi Jarvis my next step

 

That's very interesting information. Explains the issues with a majority of the boxes I've had. I too wonder if the 495Pro meets these requirements.

Hi Guys

It really does not seem like we are getting any further in this matter.

And to update on the 5.1 audio problem. It is not only in Kodi that I do not get 5.1 audio out - playing a 5.1 source video in the MyGica ATV 495Pro's default player I also do not get any 5.1 audio out. I am not even thinking about DTS............................

Tried it both on the Marantz and Denon receiver - only show stereo PCM coming in.

So please......can you do something about this or not?

Must we sell this unit as a STEREO Audio unit only? If so, bring the price down please.

Thank you

Hey guys

Sorry I have not been on the forum for the last month.

I keep pushing for this to be fixed, and have been met with no viable solution yet.
I will push even harder this week to finally get this resolved

 

I understand all of your frustrations with this, and I want to get it resolved as this has gone on way too long

So after pushing even harder, I was able to get an answer that Amlogic must help us with this issue

As the issue comes from their chipset and the Android OS SDK they have provided us.
We use the S905-B chipset, which has Dolby Hardware decoding.

So we are getting somewhere with this
I will continue to update you guys

 

Thanks

I just wonder why this was not vetted prior to product release. Now many of us are stuck with boxes that we have to hope and pray you an fix a key functional component.

This will get fixed
But yes you are right it should have been vetted prior to release.

I apologize for that, but I will get this taken care of

My point is - the problem has nothing to do with KODI - it is the My Gica box/software combination that is the problem.

I can get 5.1 though on Kodi on My Gica495Pro.....but nothing on the on the default MyGica playback software. And like mentioned before in the posts, once you do get 5.1 to work through Kodi, going back to MyGica default player, no sound at all and the box has to be restarted.

It also does not support AC3 playback.

Sort out the MyGica box default software and drivers and I am sure the rest will be fine.

Wish I saw this thread before buying this device. Would have looked elsewhere for something that supports working pass-through HDMI audio.

Yes Kripstoe, its actually sad. The MyGica495Pro could be one of the best media boxes out there if they sort out the audio multi-channel problem.

Still no updates:

 

What really irks me is i like to watch music videos on the box. Some videos are 5.1 while others are 2.0. 

So as a result, i cannot play in party mode because the moment it plays a 5.1 video, all the rest (2.0) have no audio.

 

I am in the market for a new box... And won't be recommending the Mygica to anyone going forward.

 

7 months - no resolution!!
