View Full Version : No 5.1 Audio with DTS

09-29-2010, 08:03 PM
Dear Support,

When I play MKV files with DTS audio I do not hear any sound on my 46PFL9705H. And the DTS audio is also not forwarded over the digitale coax to my receiver.

When connect my laptop to the TV through the hdmi port I get the audio to my receiver but not 5.1 audi only sterio.

I have tried everything but withought succes. Hopfully there is a solution because I am currently very disappointed in the 46PFL9705H.

Kind regards,

Jan Willem

Same problem here with a 37pfl7605h . I called philips support line and they said that (according to the specs in the brochure) the tv only supports AAC audio, no DTS and no passthrough to surround receiver.

So I end up converting my MKV's with DTS soundtrack to AAC soundtrack. I use the free "PopCorn MKV AudioConverter" for that, fantastic tool.

Dear both,
See also this topic here (http://www.supportforum.philips.com/showthread.php?623-DTS-pass-through&highlight=audio). Maybe that clarifies the question?

Dear Lebeno,

I have installed the "PopCorn MKV AudioConverter" and tried to convert some MKV files to DD 5.1 but withought succes. Can you tell me what settings you used/changed?

Kind regards,

I found this info on the web, maybe it helps:

Some Matroska containers contain different audio tracks, and with some luck, your TV or hi-fi system can cope with one of the offered alternatives. If not, then you must convert the DTS audio track to stereo or Dolby Digital.

This can be done by "PopCorn MKV to Audio Converter", when you at least allow it, during installation, to install additional components. If you do not, then the conversion may fail.

The operation is very straightforward. You only have to select the movie - or even an entire folder of movie files - and indicate the output folder. Next, you select the tab DTS to set the options you want. For example, for older equipment you can downmix to Stereo.

It is also possible to retain the original DTS track, next to the track that is converted. With the Run button you start the conversion process - a process that can take considerable time.

Besides DTS, PopCorn MKV Audio Converter can convert Vorbis, AAC and FLAC. For each of these formats you will find corresponding tabs where you can store the necessary settings.

I have also the same problem. And despite the fact that Philips wants to present DTS-passthrough as the "lacking DTS support", it is not true. You don't need a DTS license to pass-through DTS to another output as SPDIF. Numerous devices do pass DTS to their digital outputs, even if they don't support DTS decoding.

What is really funny is that older Philips models (which didn't support DTS either) could pass-through DTS. I have an 9731 (2006 model) and DTS pass-through simply works!
It never passed the mind of Philips TV designers that customers who buy Philips products do know the features older models had? And they expect newer models to have more features, and not less?

Make sure you have not selected "Preserve DTS track" in PopCorn MKV AudioConverter. If you do select it, you will have two sound tracks in your MKV, and because you can not select the sound track on the Philips TV (duh!), it will play the first soundtrack (the DTS), hence no sound.
