Soundinterruptions in HD-Movies M2TS with DTS-Master HD-Sound
« on: December 03, 2018, 05:17:12 pm »
Hello dear specialists  :)  !

I'm a german fellow, so please excuse my spelling errors ;-).
 
In general I am very satisfied with my Med600X3D Mediaplayer.
It works wells since 4-5 Years with the actual firmware.
 
There is only one annoying problem with the sound in the following case:
I have often sound-interruptions during 1-3 seconds in M2TS movies  (with complete BD file structure) when the sound is DTS Master HD 5.1 or 7.1.
The video/image  is not affected: no interruptions there, but only in the sound.
Normal DTS (Core)  or DolbyDigital 5.1, or  Dolby HD or Dolby Plus are not affected by the sound interruptions.
 
My home cinema system is the following:
 
AV-Receiver: Onkyo TX-Nr 3009.
All HDMI inputs/outputs are linked with 1.4 HDMI Cables and soundsetting is 'Paththrough there
 
The Med600X3D sends the movies from the Router/Computer to the AV-Receiver and via ARC ist's send back to the Panasonic Plasma 50 inch Full-HD TV.
I Have a Computer with Windows 7, 64Bit, 8 GB RAM, Intell Core I7 processor, connected to an external 2 TB HDD (with all my movies) via USB 2.0.
The Mediaplayer Med600X3D ist connected via LAN to my fritzbox 7490 router, wich is itself connected to the computer also via LAN.
 
 
Could you please help me:
What settings should I choose in the Med600X3D  or in the Onkyo TX-Nr 3009 to avoid the sound interruptions .. or is the USB 2.0 Connection to the HDD the bottlenec, even if the image is coming fluently ?
 
I tried so many settings without finding a solution..
 
Kind regards and many thanks for your support,
Armin Pyroth,

Hello!

You could try the following on your MED600X3D:
- Check that the picture option "Deep Color" is set to OFF (8 Bit).

But unfortunately, it seems to be a compatibility issue with older Onkyo AVRs:

Dear APMichael,

thx for your quick reply.
I will try to put deep colour to "off" in the med600x3d.

What i also tried yesterday, is to play the same DTS HD Master movie but copied from the external HDD to my internal computer HDD.
There it seems i have no sound-interruptions than... but i only tried watching for 4-5 minutes... so its not really proven yet.
Is a usb 2.0 connection maybe to slow, must it be a usb 3.0 connection to the external HDD ?  Or does this not affect the problem described.

One further comprehension question: You wrote "...But unfortunately, it seems to be a compatibility issue with older Onkyo AVRs.." -> ....shouldn't I have in this case the same problems with my panasonic blueray-player playing the same DTS-HD Master movie (burned on a bd disc) and connected to the same Onkyo-AVR via HDMI?... because i have no sound interruptions with the bluray player... this confuses me  a little bit.


Greetz,
Armin

No, USB 2.0 is not too slow. I always use a USB 2.0 HDD with my MED600X3D and never had any audio dropouts.

You can read the previously linked thread from this post: http://www.mede8erforum.com/index.php/topic,16283.msg106058.html#msg106058.

The thread describes the same problem: DTS-HD works fine when using a PC, but not with the MED.

It seems that the HDMI chipset of the MED does not play well with the HDMI chipset of the Onkyo AVRs. But it could also be a problem with the bitstream outputted by the MED. I think there is not a big chance to find the culprit anymore. :(

The 1000x3d does not have hardware accelerated interfaces. It has simple interfaces driven by drivers in the puny 1186 CPU.
Your Smart  Tv is not going to be a mega fast i/o device either. 
So you system consists of linked bottlenecks, and the sound throughput is dropping.
